Oscar Fishtooth (Fish Hooks)

Oscar Fishtooth (voiced by Justin Roiland) is a nervous, socially awkward catfish with an afro and Milo's older brother. He is an avid video game player and regularly serves as the voice of reason and justice between the main cast. He is often very stressed throughout the series, mostly because of Milo's misadventures and wild behavior. Oscar has been secretly in love with Bea until mid-Season 2, where he gets a crush on angelfish named Angela, a gamer girl on a rival debate team, who becomes his girlfriend for the remainder of the season. He is shown as a neat-freak, as well as despite being brothers with Milo, they are the opposite of each other (along with being an entirely different species). For the first season of the series, a clam named Clamantha was Oscar's stalker and regularly followed him in secret, roughly until he met Angela. After Angela spends nearly all of prom playing video games, Oscar accidentally calls her Bea, and then subsequently break up. Afterward, Oscar goes back to loving Bea, with Bea harboring feelings for him as well leading in the two becoming a couple in the series finale.
