Spitfire (Marvel Comics)

Jacqueline Falsworth Crichton, also known as Spitfire, is a mutant and vampire who was born to Union Jack, a costumed hero during World War I. In 1942, Spitfire was attacked by Baron Blood, a vampire who was also an agent of Nazi Germany. Later, she discovered that Baron Blood was also her uncle. Eventually, Spitfire came to join the Braddock Academy and the Hellfire Club.

Powers
Hyper-speed: Spitfire possesses the ability to move at superhuman speeds. She can run in excess of the speed of sound, and thanks to her vampire stamina, she can maintain this pace almost indefinitely.

Adapted physiology: Spitfire's entire body is oriented toward the rigors of high-speed running. Her cardiovascular and respiratory systems are more efficient than a normal woman's. She metabolizes an estimated 50% of the caloric energy content of foodstuffs. The chemical processes of Spitfire's body are so highly enhanced that her body does not generate fatigue poisons, the normal byproducts of locomotion which force the body to rest, as quickly as a normal human being does. Her tendons and bones have somehow become stronger in order to withstand the stresses of high-speed motion, and her joints are smoother and lubricate more efficiently than those of a normal woman. Spitfire's heightened metabolism affords her great resilience to impact-related injuries. Her reaction time is about twice as fast as that of a normal woman.

Vampire abilities: Spitfire has been shown to possess some vampire abilities, including fangs that appear when she is angry. However, she can control her blood lust and has no need to drink blood. She has vampiric superhuman strength, allowing her to lift in excess of one ton and can heal even severe wounds in seconds. Whether or not she has any more vampiric abilities has yet to be revealed.

Abilities
Spitfire is an exceptional natural athlete and fighter and has been trained by both her father and Captain America in several forms of hand-to-hand combat. She is also a trained pilot.
