Birdperson

Birdperson, briefly also known as Phoenixperson, is a friend of Rick Sanchez. He has known Rick for a long time, and has seemingly known Morty since he was a baby, as revealed in the episode "Get Schwifty". In the finale of Season 4, his cyborg form was dismantled and in Rick's possession before he was finally restored to his original form in "Rickternal Friendshine of the Spotless Mort".
