However, ORIGINALLY, Legion was going to be part of the new X-Factor team. You see, when the X-Men and X-Factor teams got together, that left the “X-Factor” title without a team, so Marvel came up with the idea of putting together the leftover mutant characters like Havok, Polaris, Madrox, Guido and Wolfsbane form a new government-sponsored mutant team.
Originally, Legion was going to be on the team, but incoming writer Peter David really did not like that idea.
He explained it to Pat O’Neill in “Comics Interview” #105:
Originally, Legion was going to be in the group, and we had a slight problem. I was extremely uncomfortable with the thought of Legion in the group simply because Legion is a story in and of himself…and comfortably working him into a group in some way that wasn’t utterly contrived was something I had a great deal of difficulty with. I don’t mind building a story around him, but working him into a group – you’re really asking for a bit much from the reader. Believing that a group of people will come together to form a team is enough of a suspension of belief….”Oh, by the way, one of them is so nuts he shouldn’t be setting foot off Muir Island”…that’s asking the reader to bend so far he will break.
Then Bob Harras called him one night to ask if David really needed to keep Legion on the team, as he didn’t like the idea of Legion on the team for the same reason. David, of course, jumped at the opportunity, since he thought it was Harras who was insisting that he be on the team in the FIRST place and thus Legion was off the team and the classic original Peter David/Larry Stroman X-Factor team was born!
