Flymon

Flymon is a Champion Level Insectoid Digimon. He can generate a high-pitched sound from his wings.

Digimon Adventure
A Flymon attacked six of the DigiDestined while they were looking for Sora and Biyomon. Agumon, Gabumon, Patamon, Palmon and Gomamon were unable to defeat it. It was defeated by the unannounced arrival of Birdramon.

Digimon Adventure 02
A Flymon was under the control of the Digimon Emperor's Dark Rings. He evaded attacks from Flamedramon and Halsemon and emitted a deafening sound long enough for him to snatch Patamon and bring him to the Digimon Emperor and MetalGreymon (under the control of the Dark Spiral). The Digimon Emperor's plan was to place a Dark Spiral on Patamon so that he could control him as he did with Agumon. That plan was ruined when Garurumon arrived in time to rescue Patamon and destroy the Dark Ring on Flymon at the same time. Later on, a bunch of Flymon under the control of Arukenimon's flute at the Giga House were fought back. When Digimon started to appear in the Real World, a swarm of Flymon was in Russia. It took the combined powers of Aquilamon, Garudamon, Unimon, Snimon and Kuwagamon to take them down and send them back to the Digital World. A Flymon was among the many Digimon seen during the final battle against MaloMyotismon.

Digimon Frontier
He makes a small appearance in episode 4, flying and obscuring the light of a sun's rays.

Digimon Data Squad
When Yoshino Fujieda and Lalamon encountered Kunemon, it cocooned itself so it can digivolve without interference.

In the end, Marcus Damon and GeoGreymon had defeat Flymon and DATS sent his Digi-Egg back to the Digital World.
