Hawk Gal is the alter-ego of Veronica that was created when Timmy wished that everyone had super powers. She ended up getting very lame powers, mainly the ability to fly very slowly.
After Timmy Turner wished that everyone in the world had superpowers, his classmates at Dimmsdale Elementary School all became superheroes. Veronica became Hawk Gal, who had the ability to fly at speeds "between 20-30 miles per hour" (about the speed of a slow moving car) which, albeit pathetic, is faster than how the average human runs.
She wears a purple costume that resembles a hawk, with yellow wings and boots. She also carries a mace. She is able to fly at very slow speeds, after she takes off with the other heroes to assist them in the battle they were heading to, it was already pretty much over by the time she got there. Her eyes are colored pink, even though Veronica's original eye color is blue.
Veronica's best friend Trixie Tang was given much better superpowers when she became Wonder Gal, so it would only be natural that Veronica got second-rate powers compared to her. Wonder Gal criticizes Hawk Gal being on the team and considers her an embarrassment. Ironically, when the actual fighting happened, Hawk Gal at least attempted to fight (albeit being debilitated, as she was knocked away by the Bouncing Boil) whereas Wonder Gal did not. When the Nega-Chin got his wish for a world with only super villains, Hawk Gal was the only one not to lose her powers. This is due according to Chester to the fact that "She wasn't much of a hero anyway."
She is a parody of the fictional Superhero Hawkgirl from Justice League, who, along with Aquaman, is usually criticized for being a useless superhero.
Although Veronica's eyes are normally blue, they are pink when she is Hawk Gal.
