Out of boredom and because  ryutheweredragon asked for an unlikable character, I give you Adrian Potts, the long-lost bastard son of Tony Stark and Pepper Potts.

Born out of wedlock, Tony Stark threw his assistant on the street when he felt she was making too many demands. Raised in poverty, Adrian used his cunning and charisma to get things his way. At the age of 23, he was a professional thief and con artist, wanted for 24 international cases of fraud and theft. To him, however, it's all part of the chase. They can run and run as fast as they can, but they can never catch him. Just to prove how no one could catch him, he broke into his father's home and stole one of his Iron Man suits, painting it unintentionally like Captain America's costume rendering. They couldn't even stop him even when he warned them, the imbeciles!

I don't know the full details on the who marvel werecreatures verse, so I'll need Ryu's help with filling me in on the details for that. But I can tell you when Adrian discovered that he himself could change to a form very much like a fox, he found the form to his liking. Now he essentially walks around in this fox form almost all the time while using the Iron Man suit he stole to do some classic crime.

Note: Keep in mind that Adrian is not evil, only selfish and used to getting what he wants. He has no love for the fight against good and evil that most other superheroes do, but rather looks out for number one. He commits crime in the thrill of the chase, and will usually return what he steals(If he feels like it). But he'd be more than willing to get his paws clean or dirty...for the right price, of course.
