Brutal killing machine built by Snydrome to both eliminate supers ("competition") as well as be a villain ready-made for him to defeat.
The OmniDroid has no personality aside from being relentless in destroying all perceived threats - or any life it seems, for that matter. It is a learning machine and continues to adapt to its opponents.
The OmniDroid has a few basic but extreme powers, essentially being a versatile brick robotic sphere with appendages. It eliminates every threat, analyzing it for weaknesses and tactics, intending to predict its opponents' actions.
