Denji Sentai Megaranger

The International Network of Excel-Science and Technology (世界科学者連邦, Sekai Kagakusha Renpō, INET) is the company responsible for the Megaranger video game used to identify five people to become the Megarangers.

The Megarangers.

Five high school students chosen by INET become the titular Denji Sentai Megaranger, with one additional member who is an INET agent. Their base of operations is the Digital Research Club at Moroboshi High School.

Kenta Date/Mega Red (伊達 健太/メガレッド, Date Kenta/Mega Reddo): 18 years old, Kenta is a slacker and knucklehead who likes yakiniku (to a point where he will ask Dr. Kubota to treat him to a yakiniku lunch for every mission accomplished), but is also friendly, playful, and has a good heart. He becomes an ideal candidate to become a Megaranger after beating a skilled opponent on INET's Megaranger arcade game, which was actually a tool used to recruit Megarangers.

Mega Red's forehead symbol is a Personal computer; ironically, Kenta is the only member who does not like computers. This symbol allows him to upload data and program skills into his mind, making him an adaptable warrior.

Kouichirou Endo/Mega Black (遠藤 耕一郎/メガブラック, Endō Kōichirō/Mega Burakku): 18 years old, Kouichirou is the functioning leader and overachiever of the team. Aside from being a keen soccer player, he is a member of the class committee and is concerned about his schoolwork. He balances his duties as a Megaranger and a student. He has a younger brother, Koujiro, who also plays soccer. A natural leader but extremely bossy, he once created an hour by hour schedule for all the Megarangers to follow but they ignored it. During his stay at the Epinard Nasu hotel in Tochigi, Kouichirou encounters a mysterious boy who is a spiritual representation of the forest that is not only in danger of Kinoko Nejire's attack on it but INET's Relay Base. He eventually gains the forest spirit's trust as he uses up all his power to help the Megarangers as Kouichirou promises to have INET relocate the relay base.

Mega Black's forehead symbol is a digital satellite, which enables him to trace communication sources and transmissions.

• Special attacks: Satellite Search, Satellite Scan, Miracle Shoot (ミラクルシュート, Mirakuru Shūto) (soccer ball kicking attack).

Shun Namiki/Mega Blue (並樹 瞬/メガブルー, Namiki Shun/Mega Burū): 18 years old, Shun is a loner who aspires to become a computer-graphics artist and initially refuses to become a Megaranger. After seeing Kenta attempt to keep the Kune Kune from interfering in his lifelong dreams, Shun reconsiders and becomes good friends with Kenta. He plays the flute, as his late mother was a world-renowned flautist. Shun is adept at creating battle strategies, such as confusing the Nejirangers by making the other Megaranger suits look like his. Shun is a Virgo, according to Miku.

Mega Blue's forehead symbol is a Digital TV, which allows him to create CG images and trap enemies in a movie dimension where characters from that dimension attack the enemy.

• Special attacks: Virtual Vision, Virtual Holograph.

Chisato Jougasaki/Mega Yellow (城ヶ崎 千里/メガイエロー): 18 years old, Chisato dreams of becoming a professional photographer. Aside from photography, she is also into singing. She is attracted to Kouichirou. Compared to the rest of her teammates, she gets the least amount of focus (sans from the episode previews).

Mega Yellow's forehead symbol is a Digital camera, which can telescopically search for people and things – even allowing her to see through walls. This symbol also allows her to record and playback anything she sees.

• Special attacks: Digicam Search, Galaxy Search, Blade Arm (ブレードアーム, Burēdo Āmu).

Miku Imamura/Mega Pink (今村 みく/メガピンク, Imamura Miku/Mega Pinku): 18 years old, Miku eats a lot, but is very self-conscious about her weight. She dislikes schoolwork just as much as Kenta, and because of this, the two of them are very good friends. She is attracted to Shun. During the Megarangers' encounter with Bibidebi on episode 17, Miku is accidentally hit by an evolution beam and becomes "Super Mega Pink" (超メガピンク, Chō Mega Pinku, 17), which makes the colored squares on her costume turn gold. As Super Mega Pink, Miku gains super strength and can wield the other Megarangers' weapons. Additionally, her intelligence increases to an IQ of 800, along with a change in her personality. However, after suffering painful side effects, Miku manages to return to her normal self. In Gaoranger vs. Super Sentai, she lectures Sae Taiga (Gao White) on the Super Sentai franchise's many female warriors and their shared skill at changing their clothes in the blink of an eye, something that Sae had never done before.

Mega Pink's forehead symbol is a Cell phone, which can track and analyze sound waves.

• Special attacks: Telephone Search.

Yuusaku Hayakawa/Mega Silver (早川 裕作/メガシルバー, Hayakawa Yūsaku/Mega Shirubā, 24–29, 32, 33, 35–38, 40–43, 46, 48–51 & Megaranger vs. Carranger): The 25-year-old chief of INET's Special Development Division, Yuusaku is one of the scientists under Kubota who created the Mega Suits, including Mega Silver which was the prototype Mega Suit. Though he is placed in charge of the Super Mega Project, Yuusaku secretly took the Mega Silver powers for his own use in helping the Megarangers despite Kubota's insistence that he gets back to work. Initially, Yuusaku's transformation into Mega Silver lasts for 2.5 minutes due to how powerful it was, but he was able to repair it by the time Nejirejia discovers this. When the main Megarangers alter their costumes to look like Shun's to trick the Nejirangers, Yuusaku confuses them even further by disguising himself as Neji Silver (ネジシルバー, Neji Shirubā, 41), armed with a twisted version of his Silver Blazer (weapon). Yuusaku also pilots his own mecha, Mega Winger. He has also demonstrated his culinary skills by preparing a lavish meal to distract a Nezire Beast before Mega Pink defeats it. In the final battle, he is able to assist the Megarangers by using his damaged Mega Winger to free the Voyager Machines from the rubble of the INET Moonbase to give the Megarangers a chance of defeating Death Nejiro and attend their high school graduation ceremony.

Mega Silver's forehead symbol is a microchip.

• Degitaizer (デジタイザー, Dejitaizā): The main Megarangers' special tool. By dialing certain number codes into the Degitaizer (worn on the wrist), they can activate their Digital Suits (デジタルスーツ, Degitaru Sutsu), call their Cyber Sliders, and launch their mecha.

This weapon can also be attached to the Mega Weapons (メガウエポン, Mega Uepon) to increase the Mega Sniper's power and the enhanced Mega Snipers can be fired together for the Final Shoot (ファイナルシュート, Fainaru Shūto) finisher.
• Drill Saber (ドリルセイバー, Doriru Seibā): Mega Red's Mega Weapon with which he can perform the Saber Slash (セイバースラッシュ, Seibā Surasshu) and Screw Drill Saber (スクリュードリルセイバー, Sukuryū Doriru Seibā) attacks. When combined with the Mega Sniper, it becomes the Drill Sniper (ドリルスナイパー, Doriru Sunaipā). The Drill Saber is broken by Yugande but soon repaired with a new capability, becoming the Drill Sniper Custom (ドリルスナイパーカスタム, Doriru Sunaipā Kasutamu) – formed when the Drill Sniper is combined with a small screw. Most of the time, this weapon is used alongside the Multi Attack Rifle. It can also be powered into the Super Drill Sniper Custom by pressing "03" on the Battle Riser to transfer its energy into the Drill Saber.
• Mega Rod (メガロッド, Mega Roddo): Mega Black's Mega Weapon with which he can perform the Rod Break (ロッドブレいき, Roddo Bureiki) attack. When combined with the Mega Sniper, it becomes the Rod Sniper (ロッドスナイパー, Roddo Sunaipā).
• Mega Tomahawk (メガトマホーク, Mega Tomahōku): Mega Blue's Mega Weapon with which he can perform the Tomahawk Hurricane (トマホークハリケーン, Tomahōku Harikēn) attack. When combined with the Mega Sniper, it becomes the Tomahawk Sniper (トマホークスナイパー, Tomahōku Sunaipā).

  • Cyber Slider 5 (サイバースライダー５, Saibā Suraidā Faibu): Mega Pink's Cyber Slider.
• Digitank (デジタンク, Dejitanku): A highly durable armored vehicle used by the Megarangers for transportation, as well as Prof. Kubota whenever he enters the battlefield on occasion. Created as the ultimate rescue tool. Can be used to enter dangerous areas or to burrow underground and has a scanner called the MultiView Searcher to scan through walls and a fire extinguishing spray. Its armaments consist of a long claw called the Digihand (デジハンド, Dejihando) and a small turret located on top called the Digital Particle Cannon (メガバーティカルキャノン, Dejitaru Pātikuru Kyanon). The Digitank was destroyed when Prof. Kubota tried to fight off Shibolena and Yugande near the finale.
• Multi Attack Rifle (マルチアタックライフル, Maruchi Atakku Raifuru): Combination of the Mega Rod, Mega Tomahawk, Mega Sling, and Mega Capture wielded by Mega Black. Most of the time, this weapon is used alongside the Drill Sniper Custom.
• Battle Riser (バトルライザー, Batoru Raizā): A special wrist-worn device given to Kenta by Prof. Kubota. It allows for powered-up chop, punch, and shooting attacks. It is also used to summon and control the Delta Mega, and to activate the Super Galaxy Mega formation. In the two final battles against the Nejirangers, Mega Silver receives his own Battle Riser to control the Delta Mega and to help fight with Mega Winger. Near the finale, Mega Black and Mega Yellow receive their own Battle Risers. In Episode 29 and Gaoranger vs. Super Sentai, Mega Pink has a Battle Riser. It is uncertain if Mega Blue received his own Battle Riser device, though Prof. Kubota once used the Battle Riser to command the Delta Mega in Episode 50 during the defense of the INET Moonbase.
  • 01: Enables a Megaranger to perform the Riser Punch (ライザーパンチ, Raizā Panchi) and Riser Chop (ライザーチョップ, Raizā Choppu) attacks, and Super Galaxy Mega to perform the Super Galaxy Knuckle (スーパーギャラクシーナックル, Sūpā Gyarakushī Nakkuru) finisher.

  • 03: Enhances the Mega Sniper's firepower by 15 times (mostly on the Super Drill Sniper Custom for the Full Power (フルパワー, Furu Pawā) finisher). This ability was originally non-functional until it was uploaded in Episode 33.
• Keitaizer (ケイタイザー, Keitaizā): Mega Silver's transformation device. It uses many of the same features as the Degitaizer (but with Mega Silver's own unique vehicle) and is also used as an actual cellphone. The device's name is actually a play-off of "Keitai Denwa", or "cellular phone".
  • 2580 – MEGA: Ranger transformation. (Transformation call is "Keitaizer, install!" (「ケイタイザー、インストール ！」, "Keitaizā, insutōru!"))
  • 259: Calls the Auto Slider.
• Silver Blazer (シルバーブレイザー, Shirubā Bureizā): Mega Silver's arm-mounted weapon that can switch between Gun Mode (ガンモード, Gan Mōdo) and Sword Mode (ソードモード, Sōdo Mōdo). His finisher is the Blazer Impact (ブレイザーインパクト, Bureizā Inpakuto) – a barrage of blasts in Gun Mode, followed by a close blade slash in Sword Mode. A variation of the Blazer Impact can be performed with just the sword slash alone.
• Auto Slider (オートスライダー, Ōto Suraidā): Mega Silver has his own Cyber Slider which is capable of transforming into Bike Auto and can fire the Slider Beam (スライダービーム, Suraidā Bīmu).
• Mega Tector (メガテクター, Mega Tekutā): An upgrade armor that the Megarangers receive in Megaranger vs. Carranger. Their finisher, Rainbow Impulse (レインボーインパルス, Reinbō Inparusu), involves them turning into balls of light and destroying their enemies not unlike the Lights of Ginga. The armor was a movie exclusive and was never used in the actual TV series.

The mecha used by the Megaranger were made by INET.

Electromagnetic Fusion Galaxy Mega (電磁合体ギャラクシーメガ, Denji Gattai Gyarakushī Mega): Combination of Mega Ship and Mega Shuttle. Initially, INET thought the Megarangers did not fully use the robot's potential and had their tactics programmer, Professor Toyokawa, install a program that allows Galaxy Mega to fight without a human pilot. But the Shrimp Nezire incident helped Toyokama to understand the negative potential and he allows the robot to remain in Kubota's control. The Galaxy Mega's last appearance in the series was when it was rendered inoperable by Burning Yugande, but was repaired and used again in Gingaman vs. Megaranger. Galaxy Mega's power helped to power up GaoKing in Gaoranger vs. Super Sentai. The Galaxy Mega's weapons are the MegaSaber (メガサーベル, Mega Sāberu), a sword which the Galaxy Mega can use to perform a wide variety of attacks; Mega Side Cutter (メガサイドカッター, Mega Saido Kattā) – a horizontal slash, Mega Flying Cutter (メガフライングカッター, Mega Furaingu Kattā) – a jumping slash, Saber Electromagnetic Whip (サーベル電磁ムチ, Sāberu Denji Muchi) – an energy whip that is used to weaken an opponent, Mega Dash Cutter (メガダッシュカッター, Mega Dasshu Kattā) – a dashing horizontal slash, Mega Cross Cutter (メガクロスカッター, Mega Kurosu Kattā) – a double diagonal slash attack that forms an X, Galaxy Lance (ギャラクシーランス, Gyarakushī Ransu) – a sword extension attack that destroys its target from a distance, Mega Flash Arrow (メガフラッシュアロー, Mega Furasshu Arō) – the saber is thrown like an arrow/spear to impale its enemy, Mega Straight Cutter (メガストレートカッター, Mega Sutorēto Katta) and Saber Electromagnetic Snake (サーベル電磁ヘビ, Sāberu Denji Hebi) – used against Toad Nejire, where Mega Pink took advantage of a toad's natural fear of snakes, by transforming the tip of the sword into a projection of a snake; Mega Shield (メガシールド, Mega Shīrudo), which can protect the Galaxy Mega and enable it to safely enter Earth's atmosphere; and Booster Rifle (ブースターライフル, Būsutā Raifuru), a gun created from the Shuttle Booster which originally enabled the Mega Shuttle to make it into space. The Booster Rifle can fire energy blasts or freezing gas to freeze opponents.

• Mega Ship (メガシップ, Mega Shippu): Orbital space station for Megarangers and Prof. Kubota. The sides and nose form Galaxy Mega's legs, and the undercarriage forms the arms while the underbelly becomes the shield. Armed with the Mega Particle Cannon. There are a hundred people who work inside Mega Ship. Following the near destruction of the Galaxy Mega by Mad Guirail and the debut of the Mega Voyager, Prof. Kubota sets up command at the INET Moonbase instead, and the Mega Ship was usually stored there in the docking bay unless if it was needed.
• Mega Shuttle (メガシャトル, Mega Shatoru): The orbiter forms Galaxy Mega's head (the engine becomes the "mullet", and the cockpit becomes the cranium). The Shuttle Booster forms the Booster Rifle (with the fuel tank holding the handle and muzzle). The orbiter docks in the nose. The Shuttle Booster can be docked to the underside of the Mega Ship. On the toy, the Shuttle Booster can also add weapons to the Mega Ship by separating into three pieces with the fuel tank becoming a cannon on the underbelly and the rocket boosters on the sides. This function is never seen in the series.

Delta Mega (デルタメガ, Deruta Mega): An additional mecha created by Prof. Kubota that is activated and controlled by either Mega Red or Mega Silver using the Battle Riser. Its program was developed by Prof. Kawasaki. One panel in the central control room was for the program to start it with another to start a self-destruct program. It made its debut in Episode 20. Comes by the command "DeltaMega Install!". Its armaments consist of two small guns known as the Delta Laser (デルタレーザー, Deruta Rēzā) and two Gatling Blaster (ガトリングブラスター, Gatoringu Burasutā) arms. However, there is a flaw in the control system which Guirail takes advantage of and uses against the Megarangers. But after Galaxy Mega sent out a wave circuit to Delta Mega its Fusion System activated, later combining into Super Galaxy Mega. When the Battle Riser is placed into the Galaxy Mega's controls it allows for the Delta Mega to combine with it to form the Super Galaxy Mega. Much like the Mega Ship, the Delta Mega was also moved and stored in the INET Moonbase's docking bay unless if it was needed following the debut of the Mega Voyager. The Delta Mega was destroyed near the finale by a powered-up Yugande, but rebuilt and reappeared in Gaoranger vs. Super Sentai.

Super Electromagnetic Fusion Super Galaxy Mega (超電磁合体スーパーギャラクシーメガ, Chō Denji Gattai Sūpā Gyarakushī Mega): Combination of Galaxy Mega and Delta Mega. First appeared in Episode 21. In this mode the Delta Mega's Gatling Blasters are positioned on the shoulders of the Super Galaxy Mega and three times stronger than normal. The Super Galaxy Mega's finisher is called the Super Galaxy Knuckle (スーパーギャラクシーナックル, Sūpā Gyarakushī Nakkuru) where it fires both fist like rockets to destroy the enemy. When the Super Galaxy Knuckle proved useless against Mad Guirail, a new attack was used; the Big Bang Attack (ビッグバンアタック, Biggu Ban Atakku). The Super Galaxy Mega spins around at high speeds, flies up into the air, and finally shots down like a comet and blasts through the Mad Guirail. Mad Guirail survived the attack.

Voyager Machines (ボイジャーマシン, Boijā Mashin): A series of mecha created by INET's Special Development Division in the Super Mega Project which Yuusaku oversees. When Mad Guirail overpowered the Super Galaxy Mega, the Megarangers obtain use of the Voyager Machines, which are launched from the INET Moonbase. The five Voyager Machines were combined into Galaxy Fusion Mega Voyager (銀河合体メガボイジャー, Ginga Gattai Mega Boijā). Mega Voyager used the top section of Rocket Voyager 3 as its main weapon for the Voyager Spartan (ボイジャースパルタン, Boijā Suparutan) finisher. When Mega Winger donates its Mega Wing, Mega Voyager becomes Wing Mega Voyager (ウイグメガボイジャー, Uingu Mega Boijā), which could use the Winger Spartan (ウインガースパルタン, Uingā Suparutan) (the Voyager Spartan shot in midair). A more powered-up version, used to destroy the last three Nejiranger, was the Mega Spartan (メガスパルタン, Mega Suparutan). Other attacks include the Voyager Kick (ボイジャーキック, Boijā Kikku), Voyager Punch (ボイジャーパンチ, Boijā Panchi), and Voyager Pulsar (ボイジャーパルサー, Boijā Parusā). Aside from using Rocket Voyager 3 as a weapon, Mega Voyager has also used Galaxy Mega's Mega Saber. It continued to be the Megarangers' primary mecha until it was destroyed in the final battle with Hinelar and Death Nejiros in the series finale.

• Rovoyager 1 (ロボイジャー１, Roboijā Wan): Piloted by Mega Red, Rovoyager 1 is a humanoid robot (based on an astronaut's spacesuit) with two large missile batteries on its shoulders. Forms the waist and upper legs of Mega Voyager.
• Shuttle Voyager-2 (シャトルボウジャー２, Shatoru Boijā Tsū): Piloted by Mega Black, Shuttle Voyager 2 is a space shuttle that can fire an energy blast from its nose. Forms Mega Voyager's head and shield.
• Rocket Voyager 3 (ロケットボイジャー３, Roketto Boijā Surī): Piloted by Mega Blue, Rocket Voyager 3 is a large rocket ship that becomes the Voyager Spartan weapon for Mega Voyager, and also becomes Mega Voyager's lower legs and abdominal area. Kenta often used it as a surfboard for Rovoyager 1.
• Saucer Voyager 4 (ソーサーボイジャー４, Sōsā Boijā Fō): Piloted by Mega Yellow, Saucer Voyager 4 is a UFO-like spaceship that can fire energy blasts from its wings. Forms Mega Voyager's body and arms, and the blasters on both sides of its thrusters attach to Mega Voyager's head. The jet engines also serve as the firing apparatus for the Mega Voyager's Voyager Pulsar.
• Tank Voyager 5 (タンクボイジャー５, Tanku Boijā Faibu): Piloted by Mega Pink, Tank Voyager 5 is a covered tank with two large cannons on top. Forms Mega Voyager's feet.

Mega Winger (メガウインガー, Mega Uingā): Personal mecha of Mega Silver, created by Yuusaku, allows him to operate as Mega Silver, as part of the Mega Space Project. It could change from Flyer Mode (フライヤーモード, Furaiyā Mōdo) to Fighter Mode (ファイターモード, Faitā Mōdo) at phenomenal speed with the command "Blitzkrieg Transformation" (電撃変形, Dengeki Henkei). It could donate its Mega Wing (メガウイング, Mega Uingu) to Mega Voyager, transforming it into Wing Mega Voyager. Mega Winger's main weapon was the Winger Cannon (ウインガーキャノン, Uingā Kyanon), which required both hands to operate. The undercarriage forms the lower legs and the "nose" becomes the arms (the inside parts spinning to become the forearms), revealing the head. The Mega Winger's final battle was in Episode 50, where it was crippled in battle against Burning Yugande while defending the INET Moonbase. But Yuusaku was able to use the damaged Mega Winger to free the Voyager Machines from the rubble of the INET Moonbase before it finally collapsed due to the earlier damage.

The following are known members of INET:

Prof. Eikichi Kubota (久保田 衛吉博士, Kubota Eikichi-hakase): He is in charge of the Megaranger program – specifically the Megaranger video game. During a surprise attack on the NASADA base by the Nezirejia, he is forced to give the Degitaizers to five students – turning them into Megarangers.

Each of the team's classmates and teachers ended up being involved in a Nejirejian scheme and they become enraged when they learned the identities of the Megarangers to which almost everyone turns against them. It was only in the final battle with Dr. Hinelar that the school realized the error of their stand and started to support the Megarangers.

Gen Ooiwa (大岩 厳 Ōiwa Gen): The class' lazy Homeroom/Science teacher. Despite his laziness, he manages to find ways to motivate his students – especially the well-disciplined Kouichirou. In episode 12, while the Megarangers battle Mole Nezire Mr. Ooiwa stumbles upon a meteorite fragment and keeps it in his possession, making him a target of the Nejirejia. When he and Mega Black are captured by Mole Nezire, he tells the overachiever to never give up. As a result, Mr. Ooiwa inspires Mega Black to break free and foil the Nezirejian plans. During the finale, despite the Megarangers being expelled, he is the only staff member not to turn his back on the Megaranger and together with Jirou and Erina start the pep rally to cheer the Megarangers on.

Gen Ooiwa is portrayed by Yoshihiro Nozoe.

Shintarou Wada (和田 シンタロウ Wada Shintarō, 6, 45 & 49–51): An overweight shy boy who has a crush on Miku. He threatened to reveal some secret photos of Miku to the school unless she would go on a date with him. Miku agrees as she thought the photos were of her transforming into Mega Pink. The photos are of her sleeping in class and the nurse's office. Shintarou was placed under the control of the Thorn Nejilar to do Dr. Hinelar's bidding until he is freed by the Megarangers. Later after the Megaranger's secret identities are exposed and Jirou is injured during the Nejilars attack, Shintarou blames the Megarangers and turns his back on them. He comes around during the final battle and cheers his friends on. Afterwards, he graduates with his classmates.

Jirou Iwamoto is portrayed by Takumi Hashimoto.

Erina (恵理奈, 37 & 49–51): A classmate of the Megarangers. After the Megaranger's secret identities are exposed, she is among the few people in the school who still supports the Megarangers and tried unsuccessfully to convince the school staff not to expel them. It is heavily implied she is attracted to Kenta. Ultimately with Jirou and Mr. Ooiwa she started the pep rally to cheer the Megarangers on, which would be instrumental in restoring the Megaranger's fighting spirit, contributing to their final victory against Dr. Hinelar and the Death Neziros. Afterwards, she graduates with her classmates.

Space Fairy Picot (宇宙妖精ピコット Uchū Yosei Pikotto): Known as the "Light of Hope", Picot is a dragon-like fairy who assumes a clam-like form while traveling to a planet where he can only grant five wishes. After fulfilling the wishes, Picot leaves the planet and would eventually return to the visited planet 100,004,000 years later. Though originally chased by Helmedor, Picot becomes targeted by the Nejireians as well. While on Earth, Picot granted Miku's giant cake wish, Kyosuke's wish for katsudon, Helmedor's planet destroying laser cannon, and Kani Nejilar's wish to bring dead Psycho Nejilars back to life. After granting Kenta's wish for the Megarangers to have for energy to keep fighting, giving them their Mega Tector armor and aiding the Carrangers, Picot leaves for the next planet.

Space Fairy Picot is voiced by Fushigi Yamada (山田 ふしぎ Yamada Fushigi).

The Evil Electric Kingdom Nezirejia (邪電王国ネジレジア, Jaden Ōkoku Nejirejia) are invaders from another dimension ruled by an entity called Javious. Their names and appearances are all twisted and distorted. They have stationed in the Death Neziros (デスネジロ, Desu Nejiro) fortress which transforms into the giant robot Grand Neziros (グランネジロス, Guran Nejirosu, 51) in the series finale. This robot can regenerate severed limbs as well as bind and electrocute his victims with cables and was finally destroyed along with the Mega Voyager in the finale. Hinelar self-destructed the Death Neziros from the inside in an attempt to blow up the Megarangers, the people in their high school and the Mega Voyager. The Megarangers nearly sacrifice themselves to carry Death Neziros with the Mega Voyager into the sky to prevent any further damage to their high school.

• Evil Electro-King Javious the First (邪電王ジャビウス１世, Jadenō Jabiusu Issei, 2–43)[Note 1] is the ruler of Nezirejia. He appears only as a giant eye on the screen of the Death Neziros. Very little is known about him and he is killed when the last of the Nejirangers, whose life forces are connected to his, are destroyed by the Megarangers. Upon his death, Javious was revealed to be the nucleus of Nejirejia which fades away upon his death. Only Javious' heart remained which Hinelar used to power his Hinelar City. Javious' heart was later destroyed along with Hinelar City. Javious the First is voiced by Ryūzaburō Ōtomo.
• Dr. Hinelar (Ｄｒ．ヒネラー, Dokutā Hinerā)[Note 2] is the leader of the Nezirejia invasion party. He was originally a cybernetics scientist named Dr. Samejima (鮫島博士, Samejima-hakase), who studied space exploring suits and lost his beloved daughter in one of his experiments, destroying his reputation and scarring him. He later worked with Kubota on an interdimensional project, being the first to discover the existence of Nezirejia. A year later, Samejima decides to enter the dimension to prove its existence in spite of Kubota's pleas not to be reckless and ends up becoming Javious', right-hand man. Kubota later realized that Dr. Hinelar and Samejima are one and the same when he recognizes that the suits of the Nejirangers are similar to the Power Suits Samejima had developed. Hinelar later plots and successfully kills Javious through the Nejirangers, to become the new high leader of the Nejirejians. After the destruction of Javious, the Nezire Dimension closes making Hinelar build Hinelar City (ヒネラーシティ, Hinerā Shiti) in which he intended to concentrate all mankind as data cards. Soon after the destruction of his city, Hinelar began his personal attack on the Megarangers after learning their identities and making sure that they become outcasts to society. But Yugande's and Shibolena's demises drove Hinelar over the edge gained a monster form to battle the Megarangers himself. However, the device that kept his body from warping on itself (a side effect from being in Nezirejia) was damaged and he retreated into the Death Neziros and turning it into Grand Neziros. When GrandNeziros exploded during the Mega Voyager's sacrifice, Hinelar dies, still inside while trying to will his body from collapsing onto itself. Dr. Hinelar is portrayed by Tetsuo Morishita.
• Shibolena (シボレナ, Shiborena, 1–50)[Note 3] is a cybernetic gynoid modeled after Hinelar's long dead daughter, Shizuka. Considers herself the masterpiece of Dr. Hinelar's work. She was second-in-command to Hinelar on the Death Neziros, a mistress of disguise and illusions. Armed with a rapier, she was also the smart one, often initiating plans for conquest. Creating Rose Nezire through her own DNA, Shibolena poses as a nun to give her offshoot's roses to children, turning them into slaves and subject them to Demon Therapy to create "Little Rose Nezire". But with one of the children being her new friend Ruri, Chisato arrives and nearly exposes herself as Mega Yellow (whom Shibolena establishes a rivalry with) to wound Shibolena with her Blade Arm. Fortunately, Mega Blue creates a holographic duplicate of Chisato to confuse Shibolena. She was critically wounded near the finale, by Mega Red, while protecting Yugande. She makes it back to the Death Neziros, to inform Hinelar of Yugande's death. Her body explodes right before Dr. Hinelar's eyes after she says goodbye to her master. The design of her hairstyle-like helmet is based on a CG illustration used as a reference. Shibolena is portrayed by Asami Jo.
• Bibidebi (ビビデビ)[Note 4] is a little annoying imp monster that begins his sentences with "Bibi" and ends them with "debi". In episode 3, Dr. Hinelar modified him with the ability to make the Nezire Beasts grow by biting them and injecting them with a Giganto Virus (巨大化ウィルス, Kyodaika Wirusu) whenever they are destroyed or are nearing defeat at the hands of the Megarangers. In secret, Bibidebi wanted to be the head of Nejirejia and has some affection for Shibolena, secretly sending Canary Nezire to act on his behalf. He appears to have died in the Grand Neziros when it was destroyed, by Mega Voyager's suicide attempt. Later, it is revealed that he teleported Hizumina out of the giant robot before the destruction.
• Yugande (ユガンデ, 1–8)[Note 5] is a prideful wire-frame model-themed robot general created by Hinelar whom he admires and unconditionally obeys. He wields the Dark Thunder (ダークサンダー, Dāku Sandā) sword. Being high-strung, Yugande offers to handle the Megarangers himself. Using a divide and conquer strategy to take out the Megaranger members one by one, Yugande gets Mega Red to fight him in subspace so no one would interfere and nearly kills him before the others manage to breach the barrier. Mega Black is badly injured as they get their teammate to safety. Later, Yugande calls Mega Red out, attacking him in his enlarged form as the others arrive to aid him. Using Galaxy Mega, the Megarangers weaken him with the Saber Electromagnetic Whip before killing him with the Mega Side Cutter. However, Yugande is later rebuilt through the Nejzre Circle in a stronger form, Yugande Relive (ユガンデ・リライブ, Yugande Riraibu, 9–31). But as he needs to get used to his upgrade, Yugande remained on the sidelines until the "Ultimate Lifeform" incident, attempting to exact revenge on Mega Red while the monster feeds. Though he manages to destroy Mega Red's Drill Saber and nearly kills him, Yugande is driven off by the Megarangers' Multi Attack Rifle. Later, he was critically wounded in Episode 30 when Guirail uses him as a shield to protect him from the Super Galaxy Mega's Super Galaxy Knuckle. Yugande was modified in a form called Yugande Strong (ユガンデ・ストロング, Yugande Sutorongu, 33–50), with various mechanical implants placed on him to survive, and is given a better sword called the Dark Crisis (ダーククライシス, Dāku Kuraishisu), which has three buttons on its handle to activate different attacks such as Dark Blade, Dark Fire, Dark Lightning, and Dark Triple Crisis (all three attacks combined). Yugande uses a special chip to take on a more powerful, red-colored form called Burning Yugande (バーニング・ユガンデ, Bāningu Yugande, 50). With this new power, Yugande proves to be a difficult challenge for the Megarangers, as he destroys the Delta Mega, badly damages the Galaxy Mega and Mega Winger and nearly destroys the Voyager Machines when he damages the INET Moonbase. Yugande, however, meets his end when the Nezi Reactor inside him is damaged and he is killed by Mega Red. Yugande is voiced by Hirotaka Suzuoki.
• Guirail (ギレール, Girēru, 19–32)[Note 6] is a bandaged warrior was one of Javious' trusted minions, he is sent to Earth to aid Hinelar with the Megarangers. Guirail used crueler methods than Dr. Hinelar's (an example of this is in his first appearance where he used children as shields), even performing unusual experiments on the Nezire Beasts. Prior to revealing himself to Hinelar's group, Guirail stages an attack to capture the children of a city district while breaking Kenta's will to fight by having him hit Takeshi by accident. However, while leading a new attack on a communication building, Guirail messes with Mega Red until he is beaten by him with the Battle Rizer. Later on, he infected Yugande to become Giga-Guirail (ギガギレール, Giga Girēru, 30). But when the Super Galaxy Mega used its Super Galaxy Knuckle attack, Guirail canceled out the fusion to use Yugande as a shield to protect himself. An angry Shibolena tries to kill him but Dr. Hinelar stopped and tricked Guirail into taking the Nezire Source Capsule that gives him tremendous power and robs him of his sanity. This mutated Guirail into an insane beast called Mad Guirail (マッドギレール, Maddo Girēru, 31 & 32) who was so powerful that the Super Galaxy Mega was no match for it. Using full power, the Super Galaxy Mega only caused him to break off a piece of his body that formed into Gigire (ギギレ, 31 & 32), who could fly through space and blast a powerful laser from his forehead. The Megarangers were able to escape to the INET Moonbase on the Delta Mega where Yuusaku gave them the Voyager Machines. In the end, Gigire, and later Mad Guirail, were the first two to be killed by the Mega Voyager. Guirail is voiced by Tatsuyuki Jinnai.
• Hizumina (ヒズミナ, Gingaman vs. Megaranger)[Note 7] is the last of Hinelar's creations and Shibolena's "Younger Sister", mostly identical save for her armor being purplish. She secretly wished to revive Hinelar having grown to miss him with Shibolena's memories, but was betrayed by Gregory when participating in reviving the Balban space pirates. Surviving the treachery, Hizumina attempts to take advantage of the fight to kill the Megarangers, only to be ultimately killed by Mega Red.
• Kunekune (クネクネ)[Note 8] are Nezirejia's grunts, having twisted faces and using twisted blades as their weapons. They are also able to assume human form.
  • Boss Kunekune (ボスクネクネ, Bosu Kunekune, 14): A black-headed version of the Kunekune able to fire energy from his hands. Posing as a police officer, Boss Kunekune leads his Nezire Army into taking over the Yuhigaoka Apartment Building in the H Ward as part of a plan to secretly replace every person on Earth with Kunkune. When Megarangers uncover the plan, the Kunekune attempt to kill off Mega Red and Mega Pink with their massive numbers before Boss Kunekune arrives to finish them off. However, after being defeated by Mega Red's Drill Sniper Custom, Boss Kunekune calls his army to group around him to form King Kunekune (キングクネクネ, Kingu Kunekune), with his head in the heart area. Because he was composed of many Kunekune, King Kunekune could close wounds in seconds. When Boss Kunekune was destroyed by the Galaxy Mega with the Booster Rifle, King Kunekune disassembled in the explosion.

The Jaden Sentai Neziranger (邪電戦隊ネジレンジャー, Jaden Sentai Nejirenjā, 38–43, 48) were created by Dr. Hinelar from Javious I's DNA as evil counterparts to the Megarangers. Their suits are similar to power suits that Dr. Hinelar had developed back when he was known as Samejima. They share an attack called Neji Energy Attack. Unfortunately, the Nezirangers were impatient and wanted nothing more than to kill their Megaranger counterparts. The Nezirangers were used by Hinelar not only to kill the Megarangers in suicide attacks, but also to kill Javious by slowly draining him of his "life energy". When badly damaged or enlarged, they transformed into their monstrous true forms. The Nezirangers' urge to kill managed to keep them from dying as they used Hinelar's data-card machine to regain physical form. They not only resume their original goal, but also to try to kill Hinelar for using them in the first place. The Megarangers manage to digitize them, preserving them as Data Cards in the now destroyed Hinelar City. Hinelar found the cards soon after the city was destroyed and sent them to where no one would ever find them.

After making a bet with Nezi Yellow to see which one of them would take away the mask of their respective Megaranger counterparts and bringing them back, Nezi Pink faced off against both Mega Yellow and Mega Pink who defeated her with a Capture Sniper and Blade Arm combo. Unfortunately, Nezi Pink managed to show them her true form of Nezi Jealous (ネジジェラス, Neji Jerasu, 40 & 48), a plant monster who gave Mega Voyager and Mega Winger a hard battle. With Mega Silver using Mega Winger as a shield while the Megarangers channeled all of Mega Voyager's power into their Voyager Spartan, they managed to use the super-powered Voyager Spartan to finally destroy Nezi Jealous. Later turned into a Data Card.

The Nezire Beasts (ネジレ獣, Nejirejū, Twist Beasts) are monsters created by Dr. Hinelar when a Nezire Egg, a capsule holding genetically altered DNA, is placed on the Nezire Magic Circle (ネジレ魔法陣, Nejire Mahōjin) and exposed to great amounts of energy, twisting and twirling while Shibolena chants a spell, "Twist and Turn.

In the end, the Galaxy Mega destroyed it with Mega Flying Cutter.
• Chameleon Nezire (カメレオンネジレ, Kamereon Nejire, 4): This Nezire was used by Shibolena to project her image across the internet with the digital camera on his shoulder, which in the process would take control of people and have them undergo "Nezirian Teaching" to make them into blood-thirsty sadists. After freeing Miss Nishiyama from the mind control with Kouichirou unconscious, Shun managed to pinpoint the address, only to fall into a trap as they were sucked into a pocket dimension where Chameleon Nezire is omnipotent as he electrocuted the four. Koichiro managed to find the real location and battled Chameleon Nezire, overwhelmed by the monster's camouflage until Mega Black use Satellite Searcher to negate the effect and managed to free the others. The others arrived in time and used their Final Shoot attack to defeat the Chameleon Nezire.
