Complete Monster/Artix Entertainment

Artix Entertainment games can't seem to keep themselves safe from the wrath of these idiots either.

"Ledgermayne: Magic is no longer yours to use as you see fit. Soon we will seal off the para-elemental plane of magic from Lore forever. You creatures will be free to fight amongst yourselves.
 * From Adventure Quest Worlds:
 * Meet Chaos Lord Ledgermayne, a plant-like being of pure magic who is behind all of the problems with magic in Lore. After preventing the players from entering the portal to the para-elemental plane of magic where it's at its strongest, Ledgermayne closes the portal to keep them from making any further attempts to enter the plane. After the players collect the Wrap of Gilead, the third and second-to-last piece of the Supreme Arcane Staff, Ledgermayne finally reveals its true purpose - it wants to seal off the para-elemental plane of magic from Lore forever. Since magic is the life-force of Lore, this means that, if Ledgermayne succeeds, Lore and all life on it will be starved off and killed. And, worst of all, Ledgermayne KNOWS THIS and doesn't care one tiny bit!

Hero: But... I thought magic was Lore's life force. If you seal off magic from Lore, won't everything die off?

Ledgermayne: Correct."

"Stalkwalker: Most children are so easy to control, especially when they give in to CHAOS. I have promised them a world without rules so that they would help me feed. Using my vines, I slowly feed on their psychic energy. Soon, my army of children will capture enough adults for me to feed on for decades.
 * Earlier, Chaos Dragonlord Vath also qualifies, as he not only enslaved the dwarves, but also his own dragon. He doesn't care how much pain and suffering he's causing the dwarves in the slightest and doesn't even care if they starve to death as, long as they can forge enough Chaos Gemeralds to keep him happy. Worse yet, Vath even threatens to enslave the rest of Lore and will even threaten to throw the bodies of anyone who tries to foil his plans down to the dwarves as a demonstration of WHAT HAPPENS to those who oppose his might!
 * We also have the Stalkwalker, who manipulates the kids with Chaos into bringing her their parents so she can feed on them, then eat the kids themselves when they're old enough and allowing their kids to take their place as her servants and repeating the whole cycle over and over again.

Hero: I get it! Then, when you start to get hungry again... the kids will already be grown-ups and you can feed on them.

Stalkwalker: ...and their children will be my NEW army!"


 * Tibicenas, the eighth Lord of Chaos, counts as well. He attempted to kill the hero on Zahart's orders - and DEFINITELY would've done so had it not been for Zhoom's interference. Later, Zahart also had him pull off a You Have Outlived Your Usefulness on one of his slaves as a reward for finding the heart of the Sphinx for him, a red diamond lost within the sands that was used to animate the Chaos Sphinx. The killing part done by Tibi himself was probably so brutal that it just had to be censored. And last, but not least, he even badly owned Saahir in a Curb Stomp Battle - one where Saahir himself suffered The Worf Effect because he didn't even last five seconds against him.
 * As if that's not enough, how about who created Vordred?.
 * ? Check. ? Check. ? Check. ? Check. ? Double check! Yeah, Chaos Lord is a monster. So much so that it's very satisfying to see him.
 * Who can forget Desoloth?
 * From Dragon Fable:
 * Drakonnan, who.
 * Davey Bones attempted to suffocate Aquella, making him a jerkass Complete Monster in his own right. His Evil Gloating and Hannibal Lecture place him even more in this spot, even if it was just.
 * Sek Duat wanted to become immortal, and to get his wish, he attempted sacrificing 100 rebels. He also killed all of the sand-elves, except for Zhoom. That crime alone is more than enough reason for Zhoom to want to kill him.
 * Frostscythe attempted to hurt Cryozen and break Vilmor's bond just for power. Since he was trying to use its baby, he didn't care whether Cryozen was alive or not.
 * Noxus reveals that he was the one who unleashed the green mist that not only killed Lady Vayle's brother Edgar, but also killed Artix's hometown. And he gleefully implies that he enjoyed it. But that's not all - in Adventure Quest Worlds, he becomes an Omnicidal Maniac and a Magnificent Bastard with plans to turn EVERYONE in Lore undead, a goal he shares with his creation, Vordred.
