Lord Hater is the most powerful and evil villain in the entire universe. He's also a whiny, insecure, selfish jerk.
Lord Hater is a tall, skeletal being. His face is a skull with ragged looking shards for teeth, and his eyes are sunken in and have green sclera with black pupils. He wears a black and red cloak with a hood covering most of his head. Behind his head, two yellow horns in the shape of lightning bolts can be seen like the watchdogs. He has skeletal looking arms and wears long, yellow, raggedy gloves over his seemingly clawed, four-fingered hands. Underneath his cloak, he wears underwear and black shoes on his feet.
Lord Hater is a power-hungry, evil, and cruel dictator. He hates being told what to do by those he declares lower than him, including his own henchman Peepers. What he desires most is absolute rule of the entire universe under his fist, and no one stands in his way. However, he incredibly hates Wander, the physical opposite of everything that he is, and cannot stand him due to his superfluous optimism, obliviousness to his evil and one-sided friendliness. This antipathy not only infuriates him, but also drives him over the edge to complete impulsiveness and attempts to obliterate Wander, even putting his plans aside just to do so. He can also be arrogant and is easily distracted when he believes he has the upper hand. But when worse comes to worse, Lord Hater is not to be taken lightly, for instance when he realized his other nemesis Emperor Awesome was almost going to receive the chance of universal control before he could, this caused him to abandon Wander and easily took out the entire Fist Fighter army with one punch while rushing to Awesome and defeated him in under a second.
Despite his reputation, however, Hater is exceedingly immature, prone to throwing temper tantrums and irrational thinking, acting more as a cranky teenager rather than an intergalactic conqueror. It is also because of this that right after he accomplishes such feats it is his own ego and overconfidence that quickly causes him to lose in a situation with one like Wander, robbing him of intimidation and his dignity. Even most of his plans are somewhat frivolous or out of spontaneous desire, such as trying to prove his reputation whenever he is hinted to be "nice" or torturing others to use their screams for a song.
Lord Hater is voiced by Keith Ferguson, who previously voiced Bloo in Foster's Home for Imaginary Friends, another show created by Craig McCracken.
The horns on his head are part of his skeleton body.
