Personally, I'm glad Cap had a minor role in the episode. I watch Evo to see the X-Men, and if I want to see the other denizens of the Marvel Universe I'll watch Spider-Man or The Avengers. And anyway, Cap's coma had a purpose. In Evo, superheroes really don't exist. No Spiderman, no Fantastic Four, etc...if people with powers were constantly in the public's eye, the reaction to the mutants' exposure in DoR wouldn't have been so huge. If heroes like Cap were still around and active, things would be grossly different.
