Gravitios started out life as a pretty normal human, except that he was rather gifted when it came to scientific engineering feats, which he had noble ambitions of using to help better society.

He developed a lightweight armor that he used to study the effects gravity and how it could be used in more practical uses for day to day life.

That was until his lab was attacked by Malta Operatives, who sought to use the armor as a means to contain and control metahumans. Gravitios happened to be wearing the armor at the time of the attack and against his better judgement used the armor to try and fend off the attackers.

During the firefight, the armor was damaged, sending a violent electrical surge throughout Gravitios' body, doing severe damage to his brain and nerve systems.

Eventually Gravitios awoke, but was no longer who he used to be. Instead, he was much more aggressive and combative...and now uses his armor to seek out vengeance upon Malta Operatives and anyone else who gets in his way.
