He then permanently digivolves into Biyomon. Puwamon is the form that Biyomon hatches out of his Digi-Egg into. However, the Rookie level is his preferred form and the one he spends most of his time in. Biyomon has the ability to Digivolve into a number of more powerful forms, each with a different name and special attack. The name 'Biyomon' refers only to the Rookie form of this Digimon. Spiral Twister ( Magical Fire): Flaps his wings, creating green flames in front of him, then shoots it out in a spiraling inferno.Like the other Digimon, after the battle against King Drasil, Biyomon returned to the Digital World. He was still no match for Craniamon, but he soon realized that Craniamon was actually there to help BanchoLeomon, taking his place to prevent the Digital world from crushing the Real World.

When Kristy decided to fight with him, her DNA appeared and Biyomon became Garudamon again. After being swatted away, Kristy told him not to fight, but Biyomon refused to due to his promise to always protect her. When Craniamon appeared in the Real World, Biyomon mistook him as a threat and tried to fight him. After Keenan and Yoshi decided to head back to the Digital World in search of Marcus, Biyomon stayed behind in order to protect Kristy and Sarah. He seemingly regained his memories by giving his statement of 'I'll always protect you'. Biyomon protected Kristy from the attack by digivolving into Garudamon. When Leopardmon attacked, Kristy was watching the battle from her balcony and one attack got past Ravemon and Rosemon's defenses. Kristy was convinced that it was the same Biyomon, and Yoshi and the others decided to help him take care of the Digimon. However, Biyomon had no memory of Kristy. He had been protecting a group of young Digimon in the Digital World, but a strange twister sucked him and the Digimon up, tossing the Digimon directly outside Marcus's house. Later, when analyzing the DigiEgg, DATS discovered Merukimon's signal mixed in with Biyomon's, and believed him to be responsible for events such as the barrier between the worlds weakening.Д«iyomon once again returned later in the series. When Kristy saw it, she said that she was glad that Biyomon no longer had to suffer. RiseGreymon defeated Garudamon, and returned him to a Digi-Egg. When not even Kristy's pleas were enough to make Garudamon come to his senses, Marcus manifested his new DNA, and allowed GeoGreymon to become RiseGreymon. Aquilamon then became Garudamon, and defeated GeoGreymon. There, he battled DATS, and overpowered the entire team, leaving only Marcus remaining to fight. Merukimon tried to make him forget the human, but Biyomon digivolved into Aquilamon and escaped, eventually appearing in the real world. It hatched, revealing Biyomon in a dazed state and having limited memories of Kristy. Upon returning to the Digital World, Merukimon sensed the 'human's evil' inside Biyomon's egg, and not even he could remove it properly. Merukimon overpowered the entire DATS team, and also reverted Biyomon to a Digi-Egg. However, Marcus's battle with Biyomon was interrupted by Falcomon, and later, Merukimon. If Biyomon remained, it could be overcome by human emotions and would have run wild, like numerous Digimon had in the past. However, when Marcus learned that if Biyomon and Kristy became partners they would be forced to join DATS, he became determined to keep Kristy out of battles and vowed to send Biyomon to the Digital World as a Digi-Egg. He became friends with Marcus's sister, Kristy, and eventually vowed to protect her. In Digimon Data Squad, a male Biyomon appeared as the Digivolved form of Puwamon, who hatched from an egg that had appeared in the real world before Marcus's family. Biyomon resembles a large, pink bird with blue-tipped feathers on his head, and a ring on one of his legs.
