The X-Maximals are mutant Transformers whose abilities and appearances are based on the X-Men. Led by Professor Wheelchair, they attend school at the X-Cybermansion. One of their kind, Magnetmaster, sought peace in order for mutants to take over Cybertron. But that will never happen- since Wheelchair keeps the X-Maximals safe from being harmed, he has Cebero, a Cerebro-like program in Cybertron to detect any mutants on Cybertron and beyond. For Wheelchair, things were worse- the Star Seekers recruited Bismarck, creator of his Sentarmies, to create Nimramrod, a Sentarmy Troop more powerful than other Sentarmy Troops. Wheelchair has other enemies too, like Armageddon, the first mutant squirrel-transformer Immoral Immortal and Armageddon's assistant Sinistor, the insane chipmunk-transformer mutant who always finds a way to keep mutants in control of the planet Cybertron. Other enemies include the Jigoku Councils lead by S'b's't'i'n Starfish, whose beloved agent Frostina betrayed him.
