Has "Green Arrow" been taken? Kinda works with the color of the car and the Pontiac arrowhead
from Wikipedia: Dressed like Robin Hood, Green Arrow is an archer, who invents trick arrows with various special functions, such as a glue arrow, a net arrow, explosive arrow, time bomb arrow, grappling arrow, fire extinguising arrow, flash arrow, tear gas arrow, cryonic arrow, or a boxing-glove arrow.
Throughout his first twenty-five years, Green Arrow was not a significant hero. In the late 1960s, however, writers chose to have him lose his fortune, giving him the then-unique role of streetwise crusader for the working class and the underprivileged. In 1970, he was paired with the more law-and-order-oriented hero Green Lantern in a groundbreaking, socially conscious comic book series. Since then, he has been popular among comic book fans and most writers have taken an urban, gritty approach to the character.
