Biyomon is a pink bird-like Digimon featuring arm-like wings, blue eyes, and a metallic ring on its left leg. It serves as the partner Digimon to Sora Takenouchi. During the events of "Digimon Adventure tri.: Future", a reboot erases Biyomon's memories of Sora. This memory loss causes Biyomon to exhibit hostility and distrust toward its human partner. The emotional distance persists until Sora reaffirms their bond. Biyomon regains its memories when the DigiDestined unlock sealed data within Meicoomon, which stored the suppressed memories. Following this restoration, Biyomon apologizes to Sora for its hostile behavior during the amnesiac period. In combat, Biyomon digivolves into Birdramon and later Garudamon to conduct aerial assaults against Ordinemon. During the final battle, Biyomon achieves its Mega form, Phoenixmon, and participates in the fusion that creates Omnimon Merciful Mode to defeat Ordinemon, resulting in Meicoomon's deletion. Biyomon's personality is characterized by loyalty and affection toward Sora, traits temporarily overridden by memory loss, causing confusion and aggression. After memory restoration, its inherent protective nature resurfaces. Biyomon typically refers to itself in the third person.
