A Giant Crocodile.

Anything that shouldn't Normally be in the sewers and moves looks delicious to him.

Jaw: It locks down once he Bites
Teeth: They are Sharp

Death roll: Once he locks his jaw on you he spins till your dead.

A child who fell into a crocodile Pit at a zoo and landed near a Mother Crocs nest in a attempt to save the Human child they Killed Croc O' Dile's Mother.
The boy had stolen an egg and rightfully deserved to die in the mother croc's eyes but was the death of her.
Later at the home of the human child, the human child's human parents found the egg and flushed it down the toilet not wanting to take responsibility for their own child.

Miraculously Croc O' Dile survived the order and the toilet some how transported him the Multiverse Sewers to feast on anything that came into his sewers including Humans who killed his mother before he was even born.
