Kyokyomon

Kyokyomon is a Baby-level Lesser Digimon. It has a long, serpentine body covered in yellow scales with ear-like spines on its head. If it gets angry it can stretch up to nearly nine times its normal length to attack the opponent, but because it only extends forward, the opponent usually avoids it completely. It has a light body like Fufumon, and floats lightly through the air, but it is able to move relatively nimbly by paddling the air with its fins.

Abilities
Kyokyomon's only ability is Metal Straw, in which it stretches out its whole body and launches a metallic spike from its mouth.
