Task Master is actually a well fleshed out version of that power fantasy I was rambling about. I’m invested.
He even has believable weaknesses. His photographic procedural memory can’t make him do super human feats, and if someone is manic or random, or has access to information he doesn’t (like being psychic) he can’t copy.
He even has a believable use for his ability, teaching other criminals how to fight. Being a teacher is a good use for being ‘good enough’ at a bunch of stuff. Narutos teacher has a similar ability.
Taskmaster is a good foil for any super hero. When I think of any character in my head, I think about their opposition, how different morals and backgrounds could change how a character uses their abilities (like evil superman melting a humans skull with his eyes, something the good one would never do). For me an interesting character cannot exists without an opposition.
