First season (Digimon Adventure)
Yokomon permentaly digivolved to Biyomon to protect Sora from Kuwagamon & later to Birdramon when the Black Gear infected Meramon attacked them. Since then, she followed Sora, despite her human partner trying to push her away at first out of fear of getting close to anyone & not loving them, which resulted from the relationship with her mother.

But when Myotismon made himself known, Sora tried to hold a wounded Biyomon back in vain- only realized that her desire to protect Biyomon stemmed from her love for her. And that very love allowed Birdramon to digivolve to Garudamon, who was an needed ally in the battles against Myotismon, the Dark Masters, & Apocalymon. But before they went their separate ways, Sora thanked Biyomon for allowing her & her mom to finally understand eachother.

Second season (Digimon Adventure 02)
One year after their adventure, Sora & Biyomon were reunited, only that Sora gave up her Crest-power to free the Soverigns. As a result, Biyomon lost the power to become Garudamon. Two years later, when the Digimon Emperor was conquering the DigiWorld, Biyomon was among the old generation Digimon to help the new gang out. One of such events was when she was stranded in the desert, only to be ambushed by a Black-ringed sheriff Starmon and thrown in jail until the gang busted her out.

She also came to the real world on Christmas eve, & on Christmas day she helps to gather the Digimon who appeared world-wide along with Control Spires, receiving a power boost from one of the DigiCores of Azulongmon, restoring her ability to Digivolve to Ultimate. But the next day, during the battle Skull Satamon of the Daemon Corps, the strain of being in the real world got to Biyomon so she & the others had to return, but not before sacrificing the energy to go Ultimate to power up Imperial Dramon into Fighter Mode. She later seen sealing the Hikarigota Gate & in the final battle against Malo Myotismon
