Deuce Gorgon is the son of Medusa the Gorgon.
Deuce Gorgon is friendly and outgoing, and very confident, making him one of the most popular monsters around Monster High. He loves sports and is one of the captains of the casketball team. He also loves cooking, but he tries to keep it a secret. He is very loyal to his girlfriend Cleo de Nile and tolerates a lot of her bad behavior with patience and grace.
Deuce is tall, handsome and muscular, with green eyes that can turn people to stone (at least for a few hours) which is why he wears glasses. His scalp hair is actually scaly and green, and on top of his head are, depending on medium, six to nine snakes, forming a mohawk (or a "snake-hawk", as Deuce calls it). He also has green scales on his bicep, though it's unclear if it is part of his natural skin or an added tattoo.
Deuce lives with his mother, Medusa Gorgon, in New Salem, although it appears they have a home on Petros Island in Greece too, which is where most of Deuce's family lives. There appears to be no father in Deuce's life. Furthermore, Deuce's relation with his mother is suggested to not be that good, most notably through Deuce's remark that "famliy is complicated". He has a cousin named Viperine.
His best friends are Heath Burns and Jackson Jekyll. Mikey is also a nice "cool guy" like him.
He falls in love with Cleo at the first he saw her. They both are now couple.
As a Gorgon, he can turn everyone into stone, by looking at them, but will turn back to normal sometime after that.
- His favorite subject is "Culinary Arts".
- He doesn't understand how Mikey can mix jellybeans, chocolate, and other weird ingredients in pizza.
- His power has no affect on Gargoyles, because they are already made of stone.
- He hates P-Shake of Mikey.
