Fischer was abandoned on the desert island of Coco Rico after pulling countless scams in Los Santos. Having nothing to defend himself with against the jeering carnivore monkeys, he came up with the slightly crazy scheme of using fish as weapons. So it was a wild man armed with a sword fish and a saw fish that charged at the Piranas when they came to bury a treasure on the island. And even though it was obvious that Fischer was not quite all there, Bloodh insisted on rescuing him because he liked the idea of a fishy, amateur conman turned blood-thirsty warrior.
