Malibu Perot, also called Maribu Peirō in Japanese, belongs to the Twin Star Troupe within the Galaxy Angel A series. Reserved and thoughtful, he enjoys reading. Malibu shares an exceptionally close bond with his twin brother, Kokomo Perot, and both brothers frequently correct misconceptions about their relationship by declaring, "We're not lovers, we're twins!"

He consistently demonstrates a rational and scientifically grounded perspective, such as advising against fortune-telling by labeling it "unscientific" and questioning if it mocks science. Malibu also pays close attention to his brother's tastes, observing that Kokomo exclusively prefers sweet foods like chocolate and ice cream while avoiding salty items. His name originates from Malibu, a brand of rum produced in Barbados.
