Mis Erable

Mis Erable (known as Hys Terical when he's happy) is a villain character that appeared in the episode: The City of Frownmorton. He is an unbelievably and ultimately miserable villain who cries and moans all the time, makes tsunamis of tears, and once destroyed Tremonton with his tsunami of tears. He felt extremely inconsolable with everyone in Tremorton feeling happier and more excited than himself, so he made everyone in Tremonton cry like him with a machine turning their happiness to misery, and turning Mis Erable's sadness into happiness.

Trivia

 * His original name "Mis Erable" is a pun on the word "miserable" which means to feel very unhappy and his new name "Hys Terical" is a pun on the word "hysterical" which means something that is really really funny.
