The New Tomorrow

• Sky (played by Nick Fenton) – He is a mysterious outsider, who first comes across The Ants, and then grows close to The Barbs and Zora, though he refuses to join any tribe. Sky's origins are a mystery, even to him.
• Dan (played by Rafe Custance), of The Ants – Initially a member of The Ants but he resists their beliefs such as their worship of the Mall Rats. He likes the way of life The Barbs have and is eventually allowed to join them after having to go through an initiation ceremony.
• Omar (played by Trey Brown), of The Ants – He is very protective of The Ants, and is distrustful of outsiders. He also dislikes Dan.
• Flame (played by Cameron Wakefield), of The Privileged – He is the leader of The Privileged and a bully. Flame really doesn't go much on Harmony or Shadow but can't say anything, because they are the closest thing to a family member or friend that he has.
• Zora (placed by Felicity Milovanovich), of The Barbs – She is the leader of The Barbs. She feels there is something familiar about Sky by asking him if he is "...sure he hasn't been in these parts before?"
• Jag (played by Joshua Rippon), of The Barbs – He doesn't like outsiders and feels that the protection of other The Barbs is important above all other things. (episodes 1–16)
• Harmony (played by Lara Custance), of The Privileged – She is the chief adviser to Flame, though she secretly harbours reservations about Flame's leadership.
• Faygar (played by Zoë Robins), of The Ants – She is the leader of The Ants, and the chief priestess in the Ants' "ancestor" religion.

• Cass (played by Paige Shand-Haami), of The Ants – She is the cook for The Ants' tribe. Cass is a caring girl who likes to help and comfort others.
• Shadow (played by James Shaw), of The Warps – He is the leader of The Warps, The Privileged's army, and bodyguard to Flame. He is a great fighter and has a battle scar over his left eye. He keeps a pet rat in his room at "The Priv" headquarters. He is later "discarded" during Harmony's coup, but soon escapes. (episodes 1–24)
• Gwyn (played by Henrietta Steventon), formerly of The Discards and then chosen to be of The Privileged – Once a Discard, Gwyn is picked to become a "Priv", though she hasn't forgotten what it is like to be Discard and treats her Discard servants with respect, unlike the other Privileged. She is later picked by the Privs to be their spy on The Barbs and The Ants, with the conditions being – if Gwyn is successful and gets useful information on the two tribes, and on the mysterious Sky, then she will remain a "Priv"; otherwise she will be thrown in The Forbidden Zone. It is on this mission that Gwyn discovers her long lost brother, Dan, who by then is a member of The Barbs.
• Erin (played by Arthur Caughley), of The Barbs – He is the younger brother of Leanne. He is often lazy, and is a mischievous trouble-maker.

• Sal (played by Abbey-May Wakefield), of The Ants – She is only 6 years old. She has a pet pig named Star, and is very protective of the tribe's animals.

• Magdar (played by Imogen Cassin), of The Discards – She is a Discard who serves Gwyn, upon the latter's joining the Privileged. Gwyn mothers and befriends the girl, but when Gwyn's position in The Privs is threatened by Harmony, Gwyn frames Magdar for theft and has her sent to the Forbidden Zone. (episodes 4–6)

• The Stranger (played by Jimmy Kwan), of The Birds – He is the youngest brother of Sunni and Lord Attil. He goes into The Ants camp during the passball game and steals Kwarli's boots, Zoot's goggles, and all of the hens' eggs. Later while Erin is fishing, he steals Erin's bicycle. He doesn't speak and is thought to be mute when first discovered by Sky and Dan. (episodes 19–26)
• Sunni (played by Garrett Chin), of The Birds – He is the brother and messenger of The Birds leader Lord Attil. (episodes 24–26)

As well as characters we have seen in The New Tomorrow, there have been mentions and representations of other people and characters from The Tribe.

The "Ants" worship Bray. Throughout Series 1–3 of "The Tribe" Bray is one of the focus characters fighting to build a new world and restore order to the city. He is taken by the Technos at the beginning of Series 4, when his girlfriend Amber gives birth to his son. Amber decided to name the baby Bray, after his dad, and so the memory lived on.

In The Ants mythology, Zoot is the evil to Bray's good. They believe that all the problems faced in the past: the technology, the machines, the darkness and the Great Wandering; were all brought about by Zoot. In the Ants story, Zoot was represented as an exaggerated form of how he looked in The Tribe. The name of Zoot is also known to both The Bards and The Privs.

The Ants are a tribe of farmers which appears to consist of the more timid survivors who were in need of someone to lead them and give them a purpose. This role has been left to High Priestess Faygar, who leads the group and has given them a belief system worshipping their ancestors. They pray to Bray (who represents good) and ask for his guidance, while Bray's brother Zoot has become the 'evil' in their mythology and the bringer of all their problems. The Ants look to the day when 'The Ancestor' will return. The Ants are easily distinguished by their markings, which consist of a black mark underneath their eyes and a line with three smaller lines in the centre of their forehead.

The Barbs are a naturalistic tribe who live in the forest and are protective of their lands and take only what they need to survive in order to conserve the environment. The warrior Zora leads them in their worshipping of the Sun, Moon and rain. They are good trackers and hunters, and can move above the forest unseen by others. In the centre of the forest is their primitive settlement of wooden huts and camp fires. The group are easily identifiable by the markings on their heads, which consist of a five-pointed fan in the centre of their forehead and a coloured mask of sorts around their eyes. (Leanne is the only one seen without this coloured mask)

The Privileged feel they are superior to other tribes and aim for perfection in both their looks and their actions. They live in the tunnels and rooms underneath an old water dam and are led by Flame. The Privileged have a group of soldiers, called The Warps, who are a strong and courageous people and a group of slaves referred to as The Discards who work in the mines and plantations run by The Privileged, or if they are unlucky they work as The Privileged's personal servants. Movement between these groups is supposed to be determined by all The Privileged, however Flame takes it upon himself to choose many of those who are forced to change groups, even going so far as to 'discard' fellow members of The Privileged at the drop of a hat. The Privs do not have a distinct marking of sorts, rather their clothes are a lot grander than those of The Ants and the Barbs. The Discards are marked by a honeycomb pattern across the centre of their forehead and gray clothing.

The Birds first appeared in episode 24 of The New Tomorrow. They are led by Lord Attil. A messenger of Lord Attil's, Sunni, arrives at The Privileged camp in the same episode. We later find out that Sunni is Lord Attil's brother. Sunni tells Harmony that his tribe has many enemies, because if a tribe refuses to trade with them, they simply take what they want.
