He grew up as a monster in the Possum City sewers. This is where the Sewer Gator legend came from.
Eventually, Creepy Mask Man discovered him, and boosted his powers, making him even uglier. He hated this, but still did what he was told. After he was beat by Fatman, he abandoned Creepy Mask Man. This was told in Fatman 5: Get a Life.
