Javier is quite a wild person, often acting inappropriate He is oddly gifted when it comes to betting on horse racing. However, in Flip Flop he has a girlfriend named Trish (Paget Brewster) and almost gets married to her.
Javier was formerly a Triple-A Baseball player and played alongside such baseball greats as Sammy Sosa and Mark McGwire. He has many connections to matadors and baseball players. He and Jay became close, but in the end Javier let him down just as he does Manny.
Jay finds Javier to be quite a dummy because of his wild nature. Jay was also insulted about Javier commenting on golf as being for old men and women who like women (probably meaning 'lesbians'). In "Up All Night", they became close but Javier ended up letting Jay down.
Javier was formerly married to Gloria before the show began. Their marriage to somehow seemed to be an imploding one as Gloria commented that all they did was "fight and make love". Gloria is also very appalled by Javier's actions, especially since he took Manny to a stripper club when he wax six.
Javier has quite a good relationship with his son Manny. Manny looks up to him and they are shown to enjoy each other's company.
