Rumor
Voiced By: Ron Perlman
First Appearance: "Rumors"
Position: In Jail
Bio: The bodyguard of inventor and businessman Paul
Karon, Mario had failed his job when, during a a demonstration of
Karon’s newest invention, a device that could break apart buildings with ease, was interrupted by The Joker. While The Batman tried to take Joker down, Karon was got in a rogue blast that caused the stage to fall down and cripple him.
Mario felt this was his fault and took some of Karon’s technology (exo-skeletons and a fabric that makes the user invisible) and began taking down
Gotham’s criminals one-by-one. Mario kept them contained in highly durable enclosures with electric fields around them and Mario planned to off all of the villains one fell swoop by using Karon’s building destroyer device. Mario was stopped by Batman and Robin and was taken off to jail.
