The Opposite Ray is an invention made by Romeo in the Season 2 episode "Gekko and the Opposite Ray" that can change people's personalities. When Romeo zaps the Opposite Ray on Catboy and Owlette, they corrupted into villains with the names 'Night Panther/Tigre Noir' and 'Dark Owl/Merlette'. The colors of their suits and eyes changed too. Romeo was also zapped by Gekko, which turned him into a hero with the name 'Captain Smarty Pants'.
