Master XOX

Master XOX is the main antagonist of Sidekick. He is the evilest villain in Splitsboro and the arch-enemy of Maxum Man, who all the protagonists are affiliated with. His alter ego is Mr. Troublemeyer.

Appearance
As Mr. Troublemeyer, XOX's appearance is generic and unsuspecting. He is a nice suburban dad with peach colored skin, neatly combed black hair, and a shortcut mustache. he wears a blue collared t-shirt with his purple tie, complete with blue jeans, a black belt with a gold buckle, and black boots.

Master XOX has the same body frame as his alter ego, albeit he is more hunched over and the hair on the top of his head falls more on the back of it. His main differences in appearance come from a different color pallet and clothing attire. He is a pale-skinned man with dark black, scrawny hair and a short mustache. He has a big, long nose, beady yellow eyes, dark purple lips, and crooked yellow teeth. Another facial feature is his butt-shaped chin. XOX's attire consists of a gray jacket and a black shirt underneath. He also wears gray pants and black boots.

Personality
Because XOX is an evil mastermind, he shares the stereotypical traits of a madman. He has a tendency to say 'evile' instead of evil. He demonstrates an incredible hatred towards Maxum Man, and an example is shown in of his room; Eric and Trevor see a bunch of Maxum Man posters with red X-marks on them. In XOX to be You, he says "pumpkin pie" whenever something goes wrong, and desires to defeat Eric for reasons unknown during the same episode.

As Mr. Troublemeyer, he demonstrates ways to hide his identity as XOX by acting polite and nice towards unsuspecting characters, which proves to be very effective. He is perfectly sane and kind in this form, and shows this by being very gentle towards the sidekicks, especially Trevor. However, he still has his hatred towards Maxum Man. Whenever he needs to vent off his anger, he makes the excuse of leaving the area for a bit, but then changes into XOX when no one is looking and lets it all out. In Endless Summer, Eric almost found out that he was XOX during a road trip, but everyone else otherwise believes that the two were completely different people.

XOX doesn't want Trevor to be evil and always tries to direct him on the good path, that's why he enrolled his son to the Sidekick Academy; the reason is unknown, but in "Wrinkle Resistant" XOX says he wants to be the only villain of the family.
