Yeah, but the point is, Iron Fist was made because he featured in the show. Any character featured in a show or movie is fair game. He may be a "nobody", but he's being popularised due in fact to Marvel wanting a Heroes for Hire TV show if S.H.I.E.L.D does well enough. It's probably the same reason Nova is on e team, if Guardians does well, Nova is a guaranteed movie, and it helps having these characters around now so kids can at least get a sense for who they are.
Any character could be made, they just need to be on the show.
Agreed on Iron Fist, I'd love to get a white and hold variant of his costume after his power up.
I love Nova. Old Nova. When he was like Spider-Man in space (this kid in Ultimate Spider-Man is a new guy).
