Cocomo Perot is an anime-exclusive character appearing in Galaxy Angel A. He leads Team Twin Star alongside his older brother, Malibu Perot, despite being the younger sibling. Cocomo bursts with hyperactive and fearless energy, marked by naive honesty and simple-mindedness. This often makes him easily coaxed into actions or schemes. He strongly resents being treated like a child due to his age.

Cocomo excels with various weapons, especially firearms and shooting-based equipment. He favors sweet foods like chocolate and ice cream and avoids salty items. A recurring trait is his emphatic denial of romantic involvement with Malibu; he frequently declares, "We're not lovers, we're twins!" when faced with such assumptions. Team Twin Star operates as rivals to the Moon Angel Troupe, driving competitive dynamics throughout their appearances.

The character's name originates from Cocomo, a Japanese brand of coconut rum. Official media, including other seasons, movies, OVAs, or spin-offs, does not explore significant character development or expanded background beyond Galaxy Angel A.
