Havok (Alexander 'Alex' Summers) is a fictional character, a mutant superhero in the Marvel Comics Universe and member of the X-Men. He first appears in Uncanny X-Men No.54 (March 1969), and was created by Arnold Drake, Don Heck and Neal Adams. Havok generates powerful _plasma blasts_, an ability he has had difficulty controlling. He is the son of Corsair, the younger brother of the X-Men's Cyclops, and the older brother of Vulcan. He often resents Cyclops' authoritative attitude and reputation as a model X-Man.
