Gaterboy

Gaterboy is a pro-wrestler and is the brother of Porcupine. He is a ½ human, ½ half unknown species hybrid mutant that got into questionable business with a crime lord. He entered pro-wrestling with his brother to get the money he needs to save his momma and their farm from the clutches of the gang. Due to this need, he ended up threatening Ben Tennyson, because the latter is the "manager" of Four Arms, who had gotten big in the wrestling world and was looking to win the prize money. After realizing what the brothers are going through, Ben helps them find and rescue their momma, as well as giving them the prize money.
Gaterboy looks like a walking alligator. He wears a green and yellow wrestling outfit, with a belt bearing the letter "G" for his name.

Skills
Gaterboy possesses enhanced strength and durability. He also uses his extremely sharp claws and teeth to attack.
He is a massive, bipedal humanoid alligator who works as an underground professional wrestler alongside his spiky mutant brother, Porcupine.
He features incredible superhuman physical strength and durability, allowing him to briefly match the raw power of a Tetramand (Four Arms) in hand-to-hand combat. He utilizes powerful tail whips, sharp claws, and pro-wrestling maneuvers.
Gaterboy appears more proactive than his brother, being the first of the two to threaten Ben in hopes of forcing Four Arms to drop out of the wrestling competition. Due to the severity of his circumstances, he was also rather stubborn, refusing the referee's orders to stay in his corner prior to his match with Four Arms. Once Mr. Beck was taken down, Gaterboy was far more amicable, and initially declined the prize money Ben offered to him, despite his family needing it to save their farm.
