Falcomon

Falcomon (ファルコモン)
A Bird Digimon that lives on 3000m-tall mountains. As its wings are not very developed, it's not so much able to fly, as it is to glide, so instead it's able to run about the craggy mountains at great speed, using its powerful leg strength. Because it has a rough temperament, you must be careful because if you approach carelessly, you will get fiercely attacked. Its Special Moves are scratching with its wing claws (Scratch Smash), and an attack unleashed through its powerful leg strength (Falco Rush).

Etymology
Falco: Short for Falcon (「ファルコン」 Farukon), which is a type of bird.
