Ace is a character from Loonatics Unleashed. He is a descendant of Bugs Bunny.
Ace Bunny is the protagonist of Loonatics Unleashed. He is an adroit, quick-witted, loyal, and action-driven leader who galvanizes his crew for each mission. He is also a very capable martial artist and swordsman.
His weapon of choice is a collapsible sword, revealed in the second season to be a Frelengian energy weapon called the Guardian Strike Sword. Before gaining his powers, Ace was a martial arts stunt double working for a movie studio. Ace is a descendant of Bugs Bunny (and quite likely, Lola Bunny) and wears a yellow uniform.
