The X-Men Roster:
Professor X AKA Professor Charles Xavier - The founder and leader of the mutant superhero group soon to be known to the world as The X-Men, Xavier is also paraplegic, although his body houses one of the world's most powerful mutant minds, yet no-one else knows this except for the X-Men. As a high-level telepath, Xavier can read, control and influence human minds amongst other things. A scientific genius, he is also a leading authority on genetics, mutation, and telepathic abilities.
Cyclops AKA Scott Summers - The first member and Field Leader of The X-Men, Cyclops produces constant powerful "optic blasts" from his eyes, forcing him to wear specialized glasses at all times and a specialized ruby quartz visor whenever he's training or out in the field.
Iceman AKA Robert "Bobby" Drake - The second to be recruited into The X-Men, Iceman has the ability of cryokinesis in which he can freeze anything around him and can also turn his body into ice. He's also now able to form a great variety of solid ice constructs including, but not limiting to, projectiles, shields, baseball bats, etc. He's also the most "mischievous" out of the group.
Angel AKA Warren Worthington III - Angel possesses a pair of large feathered wings extending from his back which enable him to fly. He's also heir to his father's multi-billion dollar business, Worthington Industries and, because of it, finds himself to be quite the "playboy". He is the third to join The X-Men.
Beast AKA Henry "Hank" McCoy - The fourth to join the superhero group, Beast possesses ape-like superhuman strength and agility as well as oversized hands and feet, though he otherwise appears to be a normal human being. He's also shown to have a genius-level intellect and an interest in a variety of scientific subjects.
Marvel Girl AKA Jean Grey - Last but certainly not least, Marvel Girl is the fifth member of The X-Men and the only female, at least for now. She's a telekinetic; possessing the cerebral ability to lift and manipulate objects with her mind. At her limit, she's able to lift weights up to the size of a standard car, but at such a mass she can only sustain it for a few seconds before it becomes too much for her.
