Protectons

• Argus "Ark" Power Electronixus (voiced by Arthur Burghardt): Leader of the Protectons. Before his transfer into his Robotix body, he was the chief-in-command of the Protectonian spacecraft city Zanadon and had a romantic relationship with Nara. He is compassionate and brave and tries to help the humans. He despises killing to the point that he would rather hurt himself than allow anybody to use him to kill another being. He almost suffered a nervous breakdown upon discovering that his mind and life force were downloaded into his robot shell. It is a monster dragon/dog hybrid with a head on a long neck usable as a ramrod and a hook for a right hand that changes into a gun and crossed between a firetruck and an airliner. Memorable transformations and features include a car-like form, a compact mode with shrunken arms and legs, laser cannons deploying from his chest and an additional K-series drone monster dog known as K-9. Pilot of choice: Exeter.
• Bront (voiced by Frank Welker): Strongest tough-guy-like member of the Protectons. Before his transfer into his Robotix body, he maintained Zanadon's command center and initiated its battle mode. He is close friends with Jerrok, who often teased him in the past because of his meager size. Their trust was strained when Bront was wrongly accused of sabotaging Zanadon's reactor and almost attacked Kontor and Jerrok, but their partnership was soon re-established. His Robotix body is a monster dragon hybrid with four wheels on walker legs extendable for river crossing that change into feet. Memorable transformations and features include a car-like form with a deployable grabber, an extreme extension of his torso to form a ladder, a deployable twin-shell canister laser cannon on his forehead and hands that transform into smaller legs and combinine into a drill, a two-man space control cockpit capsule, a cam-operated jaw, swivel joints and articulated elbows. Pilot of choice: Tauron.
• Jerrok (voiced by Neil Ross): Second-in-command of the Protectons and a friend of Bront, he helped him activate Zanadon's battle mode. He used to tease Bront as he was twice as tall as him, but after his transfer, he acquired the smallest Robotix body. It is crossed between a police motorcycle and a racing car. With that robot shell being the fastest and most maneuverable, he likes to play with his opponents while fighting them. Memorable transformations and features include hands with built-in laser cannons and extreme extensions of his arms. Pilot of choice: Sphero.
• Nara (voiced by Susan Silo): Female Robotix character in the series. Before being transferred into her Robotix body by Skalorr Penton Compu-Core "Electronix", who is the deity of the Protectons, she was his assistant and shared a romantic relationship with him. She is caring and wants to help humans as she understands how fragile they are compared to their robot shells. She is also very bright, being the first Protecton to see through Venturak's masquerade. Her Robotix body is a small dome-shaped monster dragon hybrid torso with a face mounted on four powerful legs that are also useable as arms and crossed between an ambulance helicopter and a racing tank. Her body is significantly durable, and it can remain fully operational and mobile even when some of her legs are severely damaged or even removed. Memorable transformations and features include a hoverjet-like form, an ability to slide above ground, grabber cranes deployable from her legs and laser cannons deployable from her feet. Pilot of choice: Steth.
• Venturak: When attacking the stasis chamber, Nemesis and Tyrannix manage to subdue Kontor, replacing his mind with that of Venturak, who serves as the Terrakor spy until he finally reveals his nature during the assault on Zanadon. His Robotix body was built by the Protectons from spare parts found in the Capsule Chamber and is a monster dragon hybrid with shovel arms that double as walker legs and crossed between a police carrier and a saucer. Without doubt the weakest Robotix, having no ranged weapons at least onscreen and never besting any Robotix in a fight without assistance. He appears not to have been given a Siliton crystal, instead when he protests this point to Nemesis he is flung unceremoniously to the ground, with Nemesis saying they will honor his melted remains throughout Terrakor history. Pilot of choice: Traxis.
• Boltar (voiced by Arthur Burghardt): Gentle beast of the Protectons, he is kind and supportive to his allies, but he can be a serious threat to his enemies. On one occasion, he was able to take out four Terrakors all on his own. He may be slightly mentally undeveloped, as he always speaks of himself in the third person and uses simple, short sentences (much like the Dinobots from The Transformers). His Robotix body is a bulky monster dragon hybrid torso on six thin walker legs and crossed between an ambulance van and a racing jet and he can use its front ones as arms. It is the last robot shell created in the series and was assembled and animated by Zarru and Compu-Core during their stay in Zanadon, when they found an unfinished and part-lacking Robotix in one of the hangars. Apparently, the body Boltar uses was still under construction when Skalorr's sun went supernova and was abandoned by its creators. Memorable transformations and features include a humanoid combat mode, a helicopter mode and multiple onboard weapon systems, including laser cannons and flamethrowers. Boltar did not choose his pilot, during his first battle he was piloted by Zarru, but Exeter later assigns Flexor as his partner, without any objection from the Protecton himself.
• Kontor (voiced by Michael Bell): Before the supernova cataclysm, Kontor was the main architect, designer, guardian and vice leader of the Protectons who Argus found trustworthy. He had a very short appearance, as he was ambushed by Nemesis and Tyranix in the Capsule Chamber just after he was transferred into Venturak's Robotix body and sent back into Compu-Core's essence bank to be replaced by Venturak himself. He never had any pilot or a chance to use any of his body features.
• Terragar: Briefly seen when Nemesis captures Argus and attempts to delete his personality, replacing it with a Terrakor to deceive the Protectons. Once discovered, Terragar's mind is returned into Compu-Core.

Terrakors

• Nemesis (voiced by Peter Cullen): Ruthless commander of the Terrakors who tries to take over Skalorr. In one of the flashbacks, he is seen trying to attack Zanadon with his army, but he then fails and swears death to deserters and vengeance to Argus. When it was discovered that the sun will go nova, he opted for manning the Terrastar and abandoning the dead planet, and even after transferring into his Robotix body he is willing to execute the plan. He has an obsession with obtaining Compu-Core and using it to control Terrastar, which he admires and treats with great care (as seen when Goon fails in salvaging the ship from a lake, being almost torn apart by a furious Nemesis). Unlike Argus, Nemesis sees his new body as a better chance to flee from the planet and conquer space, which helps him use his robot shell more efficiently. He trusts only Tyrannix, even if he is not always willing to show it or even throw him away. His Robotix body is a blue monster cobra hybrid and crossed between a bear and a military truck. Memorable transformations and features included a left hand capable of extreme extension and shifting into a laser gun, buzz saw, super-sharp beam whips built into hands and small treads built into his feet for high speed rolling functions. Pilot of choice: Kanawk.
• Tyrannix (voiced by Frank Welker): A cold and calculating second-in-command of the Terrakors who was transferred into his Robotix body, he has the most firepower and is also their communications expert. He is mostly loyal to Nemesis, although he overthrows him when he tires of Nemesis' failed attempts to find the Terrastar. There is no record of him before his re-awakening as a Robotix specialized for communications and mid-range combat. He has highly sensitive sensor systems, which makes him able to detect targets approaching from miles away and even accurately telling who exactly the target is. His Robotix body is a skeletal monster cobra hybrid with oversized wheels, wing-like radar solar panels, thruster pods on his legs and a twin-shell canister plasma engine on his left arm and crossed between an eagle and a military jet. As such, he sometimes walks on the ground and on other times prefers to hover and fly, as shown when he is running in the air when his leg pods are on. His arm engine also doubles as a flamethrower, laser cannon and connection thruster while in zero-gravity. He often singles out Nara in combat. Pilot of choice: Gaxon. As a fitting choice for Tyrannix, he is just merciless and cunning. He suggests stealing the last rations from Exeter's crew with considerable cruel delight and also later tries to force Argus to destroy a rock creature while briefly piloting him.
• Steggor: Most cunning and serpentine Terrakor of them all, he has a rivalry with Bront. His Robotix body is a monster cobra hybrid and crossed between a snake and a military car. Pilot of choice: Nomo. Steggor's relationship with him is the least cordial of all the Robotix.
• Goon (voiced by Corey Burton): Dim-witted grunt Terrakor who possesses little intelligence. His Robotix body is a robust build that is crossed between a shark and a military tank and even used as the head of a battering ram for the Robotix to escape the rock creatures with. Pilot of choice: Loopis, who also does not get on too well with his Robotix.

Humans

• Exeter Galaxon (voiced by Pat Fraley): Textbook leader and father of Zarru, he is brave, compassionate, intelligent, resourceful and holds his own in the face of adversity, never more so in the climactic battle where in a spaceship devoid of oxygen he still is able to steer the Terrastar towards an asteroid for intended mutual destruction of friend and foe.
• Tauron Oxus (voiced by Corey Burton): Logical, wise and oldest crew member, it is he who states to his captain it is in their interests in assist the Protectons in their battle.
• Kanawk Creant (voiced by Corey Burton): Traitorous man who often is the naysayer with his captain, he splits the crew up to join the Terrakors in a bid to get off the planet with their ship. Though he brokers the alliance with the Terrakors he often gets on Nemesis' bad side, almost being killed on their first meeting.
• Gaxon Gaves (voiced by Neil Ross): Ruthless, quiet officer who is not above sadism. He suggests they steal what little food his former crew mates have on their ship, when they consume the ill-gotten spoils and Nomo asks if they should save the double agent Traxis a portion, he says "You gotta be kidding". After his Robotix Tyrannix blasts Argus he is heard laughing, also when he briefly pilots Argus in their bid to escape the rock creatures he tries to kill, but Argus turns the gun on himself and ejects Gaxon as he only wants to escape, not to destroy. He then throws Gaxon out of his control capsule.
• Loopis Cur (voiced by Michael Bell): Character who often whines and speaks with sarcasm, poor fit to give him command of the dimmest Robotix. He briefly walks out on his faction after nearly dying with Goon, when being used as a guinea pig to reactivate the Terrastar. Loopis even tries to escape when they set up, but Tyrannix stops him.
• Nomo Ares Yel (voiced by Pat Fraley): Pessimistic and often at odds with his Robotix. He is not quite as mean or willing to fight as his group, especially when they have the Protectons without interface. Nomo is the only one who worries perhaps they are not as helpless as they look and when Steggor is savoring the moment before harming Nara he scolds him by saying "Get on with it, will you?!?".
• Traxis Lyte Janussen (voiced by Michael Bell): Double agent working for the Terrakors side, it is not clear why he openly turned down joining Kanawk, but he later accepts in secret by saying "I was hoping you'd ask!". He is the only character in the show without an American accent.
• Steth Allo (voiced by Arthur Burghardt): Medical officer, he conducts tests that shows Skalorr food is poisonous to humans, but is later revealed that applies only to their region. When Kanawk reveals his intention to leave the group and takes much of the group with him, Steth immediately says that he will divide the food, though Exeter responds to him by saying "These traitors can eat dirt for all I care".
• Flexor Tul (voiced by Neil Ross): He is the one present when the Terrakors rob the food rations from the spaceship known as the USS Daniel Boone, which was formerly a submarine. He boldly tackles Tyrannix's hand with a saucepan and his legs are crushed by a refrigerator for his efforts. Appears to have had no lasting effects as he is fully mobile for the duration of the show. He is probably afraid of big cats as he shows the most fear seeing the monstrous felid in the Rock creature volcano.
• Sphero Sol (voiced by Peter Cullen): Portly crew member, he wrongly assures Flexor is not after their ship moments before Tyrannix steals their food.
• Zarru Galaxon (voiced by Jason Naylor): Son of Exeter, he is, at times, a brash boy that gets into trouble. One point he goes off on his own to prove himself, when Flexor is chosen to be Boltar's pilot. He briefly manages to take over a disgraced Goon but Goon overthrows him, first time in the show we see the Robotix's free will is stronger than what orders are issued from the pilot.

Robotix: The Movie

In 1987, the fifteen six-minute long shorts were compiled together and released on video as Robotix: The Movie, a 90-minute feature film. In July 2003, it was re-released on DVD for Region 2 in the UK and Ireland.^[3]
