Roxy Rocket, once a low-level adversary of The Batman and a persistent thorn in the side of Gotham's citizens, seized the chaos of the undead apocalypse and the bizarre spectacle of the Wacky Races. She saw the races as a thrilling opportunity to sew chaos in new locations.
With her original sleek rocket obliterated in the early days of the ZomPoc, she followed a new path, roaring down the crumbling roads and sitting atop giant retrofitted bombs of mass destruction.
Sitting atop highly volatile high explosives would terrify most, but not Roxy. She embraces the danger and uncertainty, steering her colossal contraptions straight at her opponents until the very last second when she jumps off, sending sweet destruction straight up their tailpipes.
