Jean Grey's father. Apart from a few brief appearances during クリスマス and Jean's graduation from Bayville High, he hasn't been seen much. He, like his wife and 秒 daughter, is a normal human. No mutations, no powers.
He's a professor, though of what subject is unknown, possibly genetics (since his daughter once expressed interest in that field). He and Professor Xavier knew each other while they used to teach together in college. Thus, it was easier for him to accept that Jean was a mutant, and give her over to Xavier to teach.
