HEY FRIEND! I'm obviously not a mod so I'm not at all an authority on whether it works or doesn't, but I do have a question that hopefully will help out with the concern of flimsiness (if thats ok)!
Have you figured out why he took the belt in the first place? Because I think having a solid reason (whether it's "he had to stop a bad thing" or "he wanted to play with it and got into a situation where he had to be a hero using the belt" or anything that would explain why he took it and maybe also why he didnt give it back) would strengthen the backstory a lot. If that reason ties in with how he decided to become a superhero, I think it's even better.
also the initial reason I wanted to comment is to say oh my god tHE GRAPE FALLING OUT OF THE SKY.........(i haven't kept up with gaim but it looks like i need to start)
