one more try at the Outsiders - NO (more) MUTANTS, this time. lol
Moon Knight
Elektra
Black Bolt (I'm in the camp that prefers a powered-up, elemental Jefferson Pierce over the more common, barely-above-street-level version we usually get)
Quake
Super Skrull (considering Rex's skillset can cover all of the FF in his own ways, K'lrt is probably his closest analog in the Marvel catalog)
Spectrum
Moondragon (she's the only Marvel telepath who isn't a mutant, right?)
Aero (anyone remember Windfall?)
Werewolf-By-Night (anyone remember Wylde?)
War Machine (anyone remember Technocrat?)
Clea (anyone remember Sebastien Faust?)
and for the 00s line-up from Judd Winick's run:
Winter Soldier (Nightwing)
Echo (Arsenal)
Titania (Grace)
Absorbing Man (Shift)
Gorgon [the Inhuman, not the Mutant] (Thunder)
Starbrand (Jade)
Jocasta (Indigo)
