Antonio is Eduardo's son in the 2013 film Despicable Me 2
He is seductive and charming, he even dislikes Gru when he never tries to over-protect Margo from Antonio.
Margo meets Antonio by the wishing fountain at the mall and she develops a crush on him. Antonio invites Margo to his father, Eduardo's restaurant "Salsa y Salsa" for a cookie. Later, Gru found Margo on a date with Antonio and found out that Antonio is Eduardo's son.
Gru and the girls go to the Cinco-de-Mayo party. Antonio and Margo starts to dance and Gru tries to stop them but Antonio kicks Gru in the groin, leaving Gru to failure.
After Gru comes back from El Macho's lair, he sees Margo upset about Antonio dumped her for another girl. Gru uses a freeze ray to freeze Antonio in a block of ice, in revenge (in the deleted scene, Margo eats him).
Antonio Perez appears back in Despicable Me 3.
