Jupiter

Jupiter is a Black dogfish and the loyal and extremely vicious and violent pet of A.B Wintersvent in Mariana Bottom. It was a former guard dog during an old corrupt Mariana Bottom zaibatsu until it's destruction resulted in Jupiter being let lose as an aggressive predator, and later got adopted by Wintersvent and turned into a deadly ruthless killer of any who opposed him. He is still a vicious killer and is used by Wintersvent as a good pet, guard pet, and a good execution animal. It is a bioluminescent shark similar to the Iron Dogfish (Final boss of SuperSponge GBA/PS1 game), and is as fearsome as Goliath in Sandlot 2, as even it's original and first owners agreed that it was too fearful to live after it was almost euthanized for biting one of their children, and how it was traumatized for nearly getting killed left it to be evil and thus be a pet to the zaibatsu, and eventually Wintersvent, and anything that hurts it or it's master gets it more angry and violent.
