Classic Storm look, pre-mohawk. A very interesting character from the comics. She was worshiped as a goddess in her home country, until Professor X recruited her to join the X-Men. Talk about a step down. She led the X-Men after Cyclops left, also was the leader of the Morlocks, lost her powers, got them back. More recently, she was married to T'Challa the Black Panther and was the Queen of Wakanda. Didn't last though, after the X-Men Vs Avengers Series, she sided with the X-Men (which became a whole enemy of the state issue).
