Antonio looks like a troll with elf-like ears, long hair and bushy eyebrows. He wears black briefs, making him look like a caveman.
In Omniverse, he wears a biker outfit and a helmet with goggles. He no longer has pupils.
After Sunny was sent to Earth to live with her aunt for the summer (because of her relationship with Antonio, who apparently has a record), Antonio followed her and took Sunny on a night out in town, with himself as their mode of transportation. Sunny immediately rescheduled their plans when Sunny learned that there were more Dimension 12 robots. With Sunny and Antonio's help, they were easily able to defeat the robots, however Antonio nearly set off the bomb when he mistook it for one of the robots and thus began trying to smash it.
When Gwen decided to send Sunny home, both Sunny and Antonio immediately began fighting the team, while Gwen fought Sunny, Antonio fought Humungousaur, when he proved stronger than even Humungousaur, Ben went Ultimate Humungousaur. Ben was able to trick Antonio into zapping himself with electricity when he tore out an active light pole. After the fight, Antonio was taken back to his home world by Verdona to allow his parents to decide on his punishment.
