"Eric: There had been dozens of X-Men team members by 1992. Which of them do you pick? People don't understand that some of that evolved as we wrote it. Beast wasn't going to be part of the team. The reason we put him in prison in the beginning was so that we wouldn't see him for seven or eight episodes and there would be a reason for it. And, by the time we got to the end of the first 13, we loved writing for him so much; he became part of the team."
