I wasn't saying Thanos specifically for Captain America just in general. Cap wouldn't stand a chance. I'm just sick of seeing predictable first movie villains. But you mentioned masters of evil which will most likely be the villains for an avengers movie, if they have Loki and of course we saw what seemed to be the beginning of the leader in the last hulk movie.
Thanos is everyones villain. Just reading all his books again and that's what came to mind.
Until gambit charges up a pie and hits rogue in the face with it, make mine...... er wait...
