But some the characters we've seen can be said to be loose adaptations....Sebastion Shaw, Psylocke, Calisto for instance.
I was a big Avengers fan in the 70's and 80's, and Scarlet Witch was always a favorite of mine. I'd love to see her on film.
Although they were more involved with The Avengers, like Beast, SW and Quicksilver are usually associated with both Avengers and X-Men.
