Torcho

Torcho is the nephew of Flame King. His father was killed by his uncle in order to seize power, so he and his brother, Furnius, attempted to assassinate him by pouring ice into his ear, but they were foiled by Finn and Jake who identified Torcho by his untied shoe. He was subsequently sent to the punishment room by his uncle.
