Storm

Storm is by far the best leader of the X-Men and one of the best mutants ever (besides maybe Gambit). She is extremely powerful with weather powers so is a walking Natural Disaster when she wants to be, an actual Goddess. She is also brilliant and compassionate. Luckily all her good qualities are balanced out by her tendency to have brain farts at the worst possible times. She comes from the country of Africa , has been to space, and beat up Doctor Doom.
