Master Xox

Master Xox, (pronounced "Master zocks") is one of Maxum Man's enemies, as well as the Main Antagonist of the YTV/Cartoon Network series Sidekick. Trevor's father usually disappears when Master Xox is around due to the fact that Xox's real identity is Trevor's Father. But at the end of the episode Four's a Crowd Xox and Trevor's father exchanged shocked looks when they saw Master Xox and Trevor's father. So it is suggested they might be different people.
