Bird-Brain is a character appearing in American comic books published by Marvel Comics.
Bird-Brain first appeared in The New Mutants #55 (September 1987), and was first fully seen in The New Mutants #56 (October 1987). The character was created by Louise Simonson and June Brigman.[1]
Bird-Brain is one of the "Ani-Mates", a group of humanoid animals who the Ani-Mator created and experimented on. However, he escapes and befriends the New Mutants.[2][3] They attempt to acclimate him into human society, which fails due to his insatiable hunger. Additionally, he possesses a simplistic language that only Cypher can understand.[4][5]
Bird-Brain develops close relationships with Cypher and Wolfsbane, viewing the latter as a kindred spirit. He and the New Mutants later return to the Ani-Mator's island to free the Ani-Mates, during which he decides to live there.[4][5][6]
