Halsemon

Halsemon is a bird-beast Digimon from the Digimon 02 series, who is the result of when Hawkmon uses the Digi-Egg of Love. Is known as Holsmon in japan.

Digimon 02
Hawkmon first became Halsemon on the day of his revival when the Digimon Emperor abducted Davis. It was Yolei's love that evoked the Digi-Egg's power, allowing Hawkmon to Armor Digivolve to Halsemon, who destroyed the Dark Ring on Snimon. Since then, Halsemon has been a valuable fighter during the Digimon Emperor's reign of terror.

But once Ken renounced his evil persona, Halsemon was no longer needed and appeared only a few times as Aquilamon was used more. But during the battle with MaloMyotismon, Halsemon was manifested as a result of Yolei's dream.
