Otto

According to himself, Otto started out as a faulty A.I. Unit for a ventilator.

Five years prior to Omniverse
In the Null Void, Otto had Kevin and Argit gather technology for him in exchange for an escape. However, he double-crossed the pair and used the machinery to escape while abandoning Kevin and Argit in the Null Void.

Omniverse
Otto re-encountered Kevin and Argit at an intergalactic auto show on Khoros. At this point in time, he has become a kind of criminal boss, with the Violet Offenders as his henchmen. His plan to steal four of the most valuable cars in the galaxy came to a bad end at the hands of Kevin, Argit, Rook, and Ben, with him and his followers placed under arrest.
