One of my favorite main protagonists ever concepted. He feels so real and flawed, it's like he defines what reality really is, crowded and flawed; doesn't have a central focus. Everyone else is unrealistic in the marvel u and having adventures and fantasy escapes while he gets more stress as being a menace while stopping a super villain on Madison Square Garden and then getting shot at the cops afterwards.
That's IMO more interest than asguard, avengers hq, the Baxter building or the jean Grey school all the way up in Salem.
So yeah that's my reason. What is yours?
