Horvak is Krumm's father, and thus, not only looks like Krumm, but also carries his eyes in his hands. He lost one eye, literally, at the Battle of Lexington, when a minuteman mistook it for a bullet and used to fire the first shot of the American Revolution. He began working as a mold-farmer after flunking out of Monster Academy, although Krumm believes he dropped out willingly. He is the carrier of a family curse called "The Curse of the Krumm", which causes those affected to lose their horrendous stench.
Horvak is peach with two hands. One of his hands is wearing a black glove, because of the lost eye incident. He has a mustache.
Horvak has appeared in several episodes of Aaahh!!! Real Monsters. His first appearance was in Curse of the Krumm.
He has appeared on History of the Monster World.
