Re: Off-beat villain choice: Taskmaster!
I luh-huvs me some Tasky.
But if you pit him against "just" Cap, then all he does is mirror the super-soldier moves and shield throw. Taskmaster looks a lot more impressive when he goes up against the entire Avengers (or Heroes for Hire, or any other group), because then he gets to combine *multiple* skill sets.
