Julia Diggers
Brunhilda Brigand
G'nolga
Cassandra Cain
Prodigy (New X-men)
Now, you're probably unfamiliar with the first three, but they're from the comic Fred Perry's Gold Digger, and they're crazy good fighters. Julia and Brunhilda are the current and former champions of a Conan-esque Barbarian tribe and Julia is recognized as the greatest martial artist on the planet. And one of her specialties is Cassandra Cain-esque combat movereading, once fighting a master who was *invisible* for several exchanges based purely on prediction. Another is sort of a non-mystic variant of the Iron Fist where she puts all her power into one blow. G'nolga (her dwarven rival) and Brunhilda are just about the only two fighters in the series skilled enough to give her a run (and Brunhilda is both Julia's mother, and 8~ feet tall!).
And Prodigy? With his powers on, he's going to have the skills of *everyone* here. Friend and foe.
