Lord Dominator

Lord Dominator is one of the secondary antagonists of the Cartoon Parody episode "Disney Channel's House of Villains". She is originally the main antagonist in the Disney animated series Wander Over Yonder, who replaces Lord Hater.

She is the former lead in the Galactic Villain Leaderboard and takes pride in her mayhem the same way a bully enjoys messing with nerdy kids - and the whole galaxy is full of nerdy kids (according to Dominator herself).

Personality
In Dominatori's giant mech armor, she is an imposing silent force who drains planets dry in order to use their resources, namely Volcanium X, to power her fleet and power suit. However, under her the mask, she’s overly-enthusiastic girl who absolutely geeks out over wreaking chaos and destruction. Dominator is just as hyperactive as Wander is, if not even more so, and frequently screams, laughs, and bounces around in excitement over her own evildoing. Despite her true personality, however, Dominator is a sadistic menace through and through. Rather than conquer the entire galaxy, she wishes to destroy it for her own amusement. Friendship is a foreign concept to her, so much that she initially believed it to be another word for subservience, and she quickly wrote it off as being "dumb and way overrated" after learning that friends aren't people who follow your every command.

As hinted at by Wander, the reason why Lord Dominator acts like such a "bully," i.e., ceaselessly torments but never kills Wander and his friends, is because she's lonely and likes to spend time with them, albeit in her own cruel and antagonizing way. Although, she understands, in a way, that she longs for companionship, she continuously denies it.
