History[]
Jester Joe is a mutant hyena and a member of Grimm's Gang, a gang that consists of the leader, a mutant wolf named Grimm, a pair of hyenas Jester Jim, Jester Joe, an unnamed dog, and an unnamed fox. During their crime wave, Grimm and his gang used an EMP bomb that immobilized Sgt. Swat and disabled the police's weapons. While fleeing the police in a construction site, Grimm's gang was picked off one-by-one by the Teenage Mecha Ninja Turtles. By the time the police arrive, they find the gang, including Jester Joe, tied up. He is taken into custody afterwards.
