Lord Dominator

Lord Dominator is the main antagonist of the second season of Wander Over Yonder replacing Lord Hater. She is the former lead in the Galactic Villain Leaderboard She takes pride in her mayhem the same way a bully enjoys messing with nerdy kids, and, to Dominator, the whole galaxy is full of nerdy kids.

In the Heroes Coalition fics, she made an unexpected heel-face turn of reasons unknown. She is currently working at the Heroes Coalition as part of the Science and Research Department.

Appearance
In her original version, Dominator is a tall, humanoid alien woman with pale-green skin, red freckles, pointy ears, bright pink eyes ,  and white hair that's been shaved into a lengthy mohawk. She wears thick, black mascara and black eyeliner that's drawn on to resemble running teardrops. She wears a black crop top with spiked shoulder pads, a black, floor-length skirt with a thigh-high split on each side, and yellow gloves just like Lord Hater's. She also wears a black helmet topped with giant serrated yellow horns.

In the Heroes Coalitions storyline, she remains the same except she is currently wearing a red poloshirt over a black office jacket, black trousers and white sneakers.

Personality
Originally, she is a sadistic menace with an overly-enthusiastic personality.

In the Heroes Coalition fics, her attitude was mellowed down and seems to be friendly.

Abilities
Magma Manipulation - Dominator's most prominent ability is her power over lava, being able to generate it from her body to fire as projectiles, shape it into different weapons, or change into her battle form at will.

Optic Beam - she can demonstrated the ability to fire an energy wave from her visor powerful enough to vaporize Hater's ship in one shot.

Ice Manipulation - following the events of "My Fair Hatey," Dominator gained the power over ice and snow. She acquired these powers when Peepers attempted to destroy her ship's core with the frostonium Ray, not knowing that this would backfire. She still keeps her fire and lava powers and uses them in conjunction with this ability, making her twice as powerful. As of "The End of the Galaxy," she has become proficient in its use, shown when she created an ice sculpture decoy of Sylvia before immobilizing Wander in ice.
