Mojo's race did not evolve much because of their inability to stand upright, until a scientist named Arize developed exoskeletons that allowed a fast technological revolution. However, some members of the race refused to use them and called themselves the Spineless Ones. Instead, they used motorized platforms to transport their bodies. They also became the rulers and demanded a race of slaves to do all the tasks they could not or would not do. Arize created the slaves, humanoid beings, using genetic engineering and basing their appearance on the "demons" of the Spineless Ones' nightmares - which were actually the characters of TV broadcasts of Earth-616, somehow scattered throughout their timeline and perceived by the Spineless Ones. Unknown to the Spineless Ones, Arize secretly planted the seeds in their genetic make-up to eventually turn on their masters and rule Mojo-world justly. Arize was banished by the Spineless Ones when he refused to build weapons for them.
