Jack the Ripper is a fictionalized version of a real-life serial killer. The character, created by Brian Augustyn and Mike Mignola, first appeared in Gotham by Gaslight #1 (February 1989). Jacob Packer had been trained in both medicine and law by Thomas Wayne but Martha Wayne rejected him. Packer hired an assassin to kill the two and afterwards killed women to silence his own insanity. Jack the Ripper frames Bruce Wayne for his killings in Gotham City. A trial is held in which Packer is a defense attorney. Bruce is convicted, sentenced to be hanged and imprisoned in Arkham Asylum but eventually figures out the killer's identity and escapes from prison with Alfred Pennyworth's help. Batman confronted Jack the Ripper throughout Gotham and the two eventually come to the graves of Thomas and Martha before he was killed by Inspector James Gordon.[1]

Aubrey James is a fictional character appearing in American comic books published by DC Comics.

Aubrey James was the mayor of Gotham City and a friend of Thomas Wayne. He was later stabbed to death as mentioned in The Madmen of Gotham.[2]

Java is a fictional character appearing in American comic books published by DC Comics.

Java is the Neanderthal servant of Simon Stagg. He was first discovered by fortune hunter Rex Mason and revived by the scientific wizardry of Stagg Enterprises. Java was present the day that Mason discovered the Orb of Ra inside the pyramid of Ahk-Ton in Egypt. The Orb was responsible for transforming Rex Mason into the metamorphae known as Metamorpho the Element Man after Java knocked out Rex Mason in the presence of it.[4]

For years, Java lusted after Simon's daughter Sapphire Stagg, but was unable to win her heart because she was in love with Metamorpho. This bred a bitter rivalry between the two; one that persisted for many years. Java even risked his life once to save Sapphire from a melting skyscraper, and was transformed into a petrified fossil for his actions. Stagg's scientific prowess saved his life and returned him to normal.[4]

During a time when Metamorpho was believed to be dead, Sapphire relented to Java's persistent advances and married him. Java became the father figure to Sapphire and Rex's mutant son, Joey. Java was not an inherently evil individual, but his moral base had been compromised due to his constant exposure to the unscrupulous Simon Stagg. He was also extremely selfish when it came to his wants and desires. When Rex abducted Joey from Stagg Mansion, Java flew into a rage and was determined to kill him. Even Simon's command over him could not quell Java's emotions. Frustrated by the Neanderthal's rare act of defiance, Simon Stagg shot him in the head, seemingly killing him.[5]

Java did not remain dead for long however. The means behind his resurrection are unknown, but he was seen once again several years later attending the funeral of Metamorpho (who at the time was believed to be dead).[6]

During the "Brightest Day" storyline, Java was with Simon Stagg at his Canadian estate at the time when Metamorpho persuaded him to help him and the Outsiders get back into the United States. Later that night, Java pays Metamorpho a visit while he was sleeping. For some reason, Java still had the Orb of Ra in his possession. Java uses the orb to knock Metamorpho around until Metamorpho becomes unconscious.[7] Java then takes Metamorpho's body down to Simon Stagg's lab where he plans to merge him with Chemo. It doesn't go well as Java calls in Simon Stagg's servant Freight Train to help stop it. Freight Train manages to use an electrical wire which causes Chemo to vomit out Metamorpho.[8] Simon Stagg later did an unidentified experiment that enabled Java to transform into a Shaggy Man which was defeated by Freight Train.[9]

In 2011, "The New 52" rebooted the DC universe. Java's history with Simon Stagg and Rex Mason remains the same.[10]

Java was present when Simon Stagg had opened a portal to the Dark Multiverse and is trying to close it with Metamorpho who was transmuted to Nth Metal.[11] He is present when Mister Terrific, Plastic Man, Metamorpho, and Phantom Girl return from the Dark Multiverse.[12]

Java was revealed to have been operating as the villain Doctor Dread and has formed a counterpart of the Terrifics called the Dreadfuls. They were defeated by the Terrifics.[13]

The Javelin is a fictional DC Comics supervillain.[14]

The Javelin is a former German Olympic athlete who turned to a life of crime, using his uncanny abilities with a javelin-based weapons arsenal. The Javelin fought Green Lantern and was defeated before agreeing to serve with the Suicide Squad in exchange for the purging of his criminal record. His last Squad mission was a battle with Circe as part of the War of the Gods crossover event. It takes place in issue #58.

In the pages of Checkmate, the Javelin is recruited by the Mirror Master in an attempt to frame Amanda Waller. He teams up with several other villains, such as Plastique and the duo Punch and Jewelee. They invade a Myanmar military facility to neutralize what seems to be a superhuman power source. The Javelin is killed by a runaway jeep while trying to protect a distraught, newly widowed Jewelee.[15]

Jefferson Jackson is a supporting character of Ronnie Raymond (a.k.a. Firestorm) who makes his debut in Firestorm (vol. 2) #1 (June 1982). Jackson is a former student of Bradley High School in Manhattan, New York. During his tenure at Bradley High, Jackson became a member of the school's championship basketball team, where he met Ronnie. The two became close friends, and Jackson frequently aided Ronnie during the numerous episodes wherein the latter would find himself embroiled in conflicts with school jerk Cliff Carmichael. Jackson dated a young woman named Stella, and the two frequently double-dated with Ronnie and his girlfriend, Doreen Day.

Rhea Jones is a fictional character appearing in American comic books published by DC Comics.

Rhea Jones was the daughter of an Air Force official. After tagging along with her father to a government base in the Arctic, an explosion involving a powerful radioactive electromagnet killed her father and granted her electromagnetic abilities. Rather than stick around and be dissected and experimented on by the army, she ran away and joined the circus. After a few years, Rhea was recruited by Arani Caulder to join her new Doom Patrol.[20]

After being recruited by Arani Caulder, aka Celsius, Rhea was now one of three new recruits into the Doom Patrol, along with Scott Fischer and Wayne Hawkins aka Karma. Celsius gave her the codename Lodestone. Her demonstrated abilities allowed her to fly, give herself Earth reinforced superstrength, create limited force fields, and attract or repel metallic objects like bullets.

Following the Invasion! storyline, Rhea and Scott were struck by a disease created by the Dominators. Her powers went wild, and then she lapsed into a coma, but ultimately she lived while Scott died.

At the start of Grant Morrison's surrealistic run of the Doom Patrol, Rhea was put into a coma that would last until halfway into the series. While in the hospital, she was kidnapped by the butterfly collector known as Red Jack, who claimed to be God, Jack the Ripper, and many others. He sought to make Rhea his bride. The new Doom Patrol followed Jack into his house, which our world is a room in. As he battled the Doom Patrol, Rhea awoke from her coma and stabbed Jack in the back, then immediately became comatose again.

Brought back to the Doom Patrol's new mountainside headquarters, Niles Caulder, the Chief, did experiments on Rhea showing that her coma wasn't normal. She was instead going through a form of metamorphosis, and her human form is the chrysalis.

Rhea awoke from her coma in issue #36 during "The Orthodoxy/Geomancer War". It was revealed that she was The Pupa, a weapon sought by the aliens Orthodoxy and Geomancers. Rhea's original body shattered, and out emerged a magnetic butterfly, explaining why she was sought out by Red Jack. After awaking, her facial features disappeared and her eyes were now on her chest and back. Her ears had also become two twinkling lights. She no longer wears clothes and seems to think nothing of it.

Rhea was actually what some call a Lodestone, a being in tune with the Earth's electromagnetic waves, its nerve system. They are the Earth's expression in flesh. The Ultraquist Geomancers kidnapped Rhea, and Rebis in the process, before she was able to fully bond with the Earth.

After ending the conflict between the Orthodoxy and the Geomancers (with help from Rebis and Robotman), Rhea pointed out a bright star in the sky, and left to go visit it. Promising to visit, she has not been seen since.[20] Her only subsequent appearance to date has a brief flashback to her early days with Arani Desai and Valentina Vostok when the two returned during Blackest Night.[21]

Tao Jones is a fictional character appearing in American comic books published by DC Comics.

She was among the children that were experimented on by Doctor Love while they were still in their mother's womb where she developed forcefield abilities. She becomes a member of Helix where they fought Infinity, Inc. on occasion.[22]

Jumpa is a fictional character appearing in American comic books published by DC Comics.

On Earth-Two, Jumpa is a Kanga who was Wonder Woman's favorite Kanga and serves as her mode of transportation on Themyscira.[23]

In 2016, DC Comics implemented another relaunch of its books called "DC Rebirth" which restored its continuity to a form much as it was prior to "The New 52". During the "Infinity War" storyline, a flashback to Wonder Woman's childhood had Wonder Woman working to train Jumpa while riding through Themyscira. Jumpa threw Diana into the ocean where the Megalodons that protect the ocean nearly attacked her. Hippolyta saved Diana and advised her to train Jumpa better.[24]

The Judge is an alias used by different fictional characters appearing in American comic books published by DC Comics.
