Giromon

Giromon is a Machine Digimon whose name is derived from the onomatopoeia for glaring (「ぎろぎろ」) and whose design is derived from a Naval mine. It patrols within the Computer Network while floating lightly in the air, and is designated with the alias "Net Keeper". It is surely a frightening Digimon, as when it judges an intruding Digimon to be an opponent, it will repel them with all the attacks it is able to muster, and if it is driven into a predicament, it will completely annihilate the intruder by blowing itself up.
