He moved to America as a young boy, but cannot remember where from. He joined the army and made a pact with the Hellfish. The last remaining Hellfish (who was alive) would get the hellfish bananza, full of painting worth millions. Grampa and Mr. Burns were the only two left, and Burns tried to kill Grampa, but failed.

When they got the paintings, they were taken by the police and given to the decendant of their rightful owner.

In other universes, he has had superhuman strength and been a member of Oldblood.
