I created a character for a "Champions" RPG I played in a few years ago that combined the powers of Captain America and Dare Devil - I called him Major Victory (corny, I know, but he was really cool to play). the game was set in a more Marvel-like setting (mutants, S.H.I.E.L.D. type organization, etc.).
i would defineatly make a guy in marvel, u should visit my thread

is where u post the names and powers of mutants that u have created.
id base mines in the MU, and have his mutant power be complete agility,
Did you ever read Slingers? It was 4 new heroes taking up the mantles that Spidey left behind in the wake of Identity Crisis. The new Ricochet was really cool and that was basically his power. Mutant "hyper agility" on the level of Spider-Man. Also had a precognitive danger sense which tied into his agility.
I had mine posted a long ways back, the person can psionically control their blood, as such giving them Gypsy Moth/Skein type powers, making tendrils and whips he or she can control mentally, wings, etc.
