Manuel Alberto Javier Alejandro "Manny" Delgado (Revealed in Queer Eyes, Full Hearts) is Gloria's son from her previous marriage, who is very outgoing and has evolved from being not the least bit self-conscious to maybe being even overly conscious about his outfits. He is very mature and intuitive for his age and is often shown doing adult-like things, such as having conversations with Claire about her marriage and kids, drinking coffee and handling problems like a man. He has inherited his mother's passion for life which causes him to be very romantic. His support is mainly channeled through his mother Gloria and almost nonexistent in his stepfather Jay, who in the recent episodes has been getting a bit closer to Manny.
Manny isn't afraid to take chances, leading him to ask out older girls, and develop somewhat of a crush on Haley. Once something goes wrong he never gives up. He idolizes his absentee father often speaking about him in a positive light, even after being repeatedly flaked on. He plays for a soccer team and fences. He is also shown to have a big fear of butterflies, which was never shown in Season 1, however, it was shown on several instances in Season 2.
Throughout all the Modern Family seasons, Manny has not been afraid to show his affection towards his crushes.
In season 1, he was chubby wubby, but in season 4 he was skinny winnie as Gene Kelly.
