The funny thing about this one, I haven't finished the game (Yet) and I fell short watching the cartoon after episode 5 (Bigger fish to fry at the moment), yet, I still consider myself a fan.

Name: Master Chip (Or, sometimes "Chippy" by his DNA Sources/Brothers)

Age: Physically the combined age of the twins.

Abilities: The same as his "Brothers" except he's a lot stronger.

Backstory: Commissioned by the devil as a super weapon to collect Cuphead and Mugman's souls, Dr. Kahl created a binary clone of the brothers who due to mixing their personalities (Cuphead's bullheadedness and Mugsy's caution), he went rogue before the Devil had a chance to control him. Now he's on of the Inkwell Isles' greatest heroes...The Scar came from an accident during a heated game of Crokinole.
