Antonio is the son of Eduardo Perez, the proprietor of "Salsa y Salsa" Mexican restaurant on the upper level of the Paradise Mall.  When he's not generally being a mallrat, trying to woo the local girls and playing video games, he's hanging around his father's restaurant.  Just how much Antonio knows about his father's alter ego, the supervillain El Macho, is unclear, but its a fair bet that he knows a great deal.

Antonio walks around with a confident, suave Latin swagger, constantly pulling teen hair flips and shooting girls a cool seductive glance.  It works quite well on Margo, and Antonio becomes her first real crush...much to Eduardo's delight, and Gru's consternation.

He wears a black leather jacket, purple shirt, blue knit tie (worn loose around his neck), blue jeans, and black Macbeth sneakers.  When he's hanging around the Paradise Mall, he enjoys scarfing down cookies and playing video games.  His greatest hope in life is to play video games professionally.
