Lord Big Rabbit is an rabbit alien of the Cenourano planet. He is an arrogant dictator obsessed with power trying to dominate kingdoms although weakling and a coward. His name is almost a paradox, because it is as small as a normal rabbit unlike others of its kind.
He wears a black mask and cape that parodies the Darth Vader of the Star Wars franchise. To be weak he has a fleet of robots to do their service, and always accompanied by his henchman Zoiudo, a talking dragonfly. Even with their efforts to conquer planets Lord Big Rabbit always fails in his plans for his stupidity and arrogance as well as many villains and takes a beating Monica and her friends at the end.
