Thanks to William Moulton Marston's wife, Wonder Woman is a heroine, not a hero. Created out of a reaction to the Axis Powers in World War II, Marston wanted Wonder Woman to be a female superhero in the model of Superman or Captain America. Originally printed in 1941, this female superhero was the first widely-known female superhero. As an Amazonian woman known also as Diana, Wonder Woman's powers are second only to Superman, as she has strength and speed, an affinity for animals and a kind heart that makes her intuitive. She's a founding member of the Justice League.
Born Jean Gray, this super heroine first experienced her telepathic and telekinetic powers at age 10. Her parents sought help with the development of her powers from Professor Charles Xavier; while he was counseling her, she telepathically traveled in the form of a Phoenix and first saw her lifelong love Scott Summers. Dr. Xavier prevented her from using her powers until she was old enough to control them. Once she matured, Jean became a member of Xavier's team of mutants known as the X-Men and was initially called Marvel Girl. She became Phoenix after she began dying from radiation poisoning and was saved by the entity Phoenix Force, whose identity she assumed.
Just a normal suburban young girl, Katherine Pryde, known as Kitty, found out she wasn't so normal; she was a mutant with phasing powers. After her parents were murdered by a group of infinites, Kitty joined the X-Men and became Shadowcat. She had the ability to disappear, move through objects and walk on air. As the youngest member of the X-Men, Kitty formed a relationship with Colossus, and they married. Shadowcat's marriage to the volatile Colossus would prove fateful, when he crushed her to death.
There are four incarnations of Aquagirl; the first, Lisa Morel, appeared in 1959. She was one of many Atlantean children who were unable to breathe underwater so she was sent to live among humans. When the venerable Aquaman was threatened, her ability to breathe under water surfaced and she battled alongside him. Unfortunately, her powers were fleeting and disappeared.
The second Aquagirl was Selena in 1963, followed by Tula from 1967 to 1985. The modern-day Aquagirl is Lorena Marquez, who has been Aquagirl since a 2004 issue of D.C. Comics' "Aquaman," when San Diego became submerged after an earthquake; Lorena found that she could breathe underwater. Aquagirl was most recently seen as a member of Teen Titans.
