Arize

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.

It was revealed that because of Mephisto's manipulation of Shatterstar by sending him back in time to the Mojoverse (along with Rictor), he was discovered and experimented on by Arize who created Longshot from his DNA, essentially becoming his father. This created a paradox when Longshot impregnated Dazzler who then gave birth to Shatterstar. Longshot and Dazzler were mindwiped to forget the pregnancy and the Shatterstar infant was sent 100 years to the future in order to maintain the consistency of the time line.

Eventually, Longshot returned to free the slaves and deposed Mojo, with the help of Mojo's upright, more human looking (although yellow) clone Mojo II. However, Mojo II turned out to be just as bad as his predecessor and Longshot had to defeat him as well. After Mojo II was ousted Mojo reclaimed his position and became the leader of Mojo World once more
