The robots have always been fascinated by comic book superheroes, and Iron Man is a favorite. For obvious reasons, I suppose. A human that dons a robotic shell? Anyway, they do quite well at cosplay given access to a few cans of spray paint!
I tried to explain the concept of “costumes” to them but the robots weren’t having any of it. “Why would we not want this to be permanent? We are Iron Man. Technically we’re metal alloys and composites but we are still Iron Man.”
