Cthyllamon

Cthyllamon inhabits the depths of the Net Ocean, and is known by the alias "Phantom of the Ocean" due to the fact that only the skull pattern on its chest can be seen floating eerily in the dark sea. Instead of actively fighting on its own, it employs aquatic Digimon that are a lower Level than itself by brainwashing them, and has a crafty and cunning disposition. Because of its appearance, and since it is rarely ever seen, it shares many similarities with Marin Angemon, but the relationship between them remains unknown. Its Special Move "Ocean Hell", in which it steals the opponent's fighting spirit with an aura of endless terror akin to the darkness at the depths of the sea, sometimes reduces Digimon that suffer this technique to being Cthyllamon's puppets. Its "Buccal Rush", in which it opens its mouth wide and attacks with its three long, flexible tongues in a whip-like manner, and its "Aqua Grinder", where it generates an intense whirlpool that bores into the opponent's body like a drill, possess destructive power that is unimaginable from its tiny physique.

クティーラモンはネットの海の深部に生息し、暗い海の中で胸のドクロ模様だけが不気味に浮かび上がって見えることから別名「海の死霊」と呼ばれている。自ら戦うことに積極的ではなく、自身より程度の低い水棲デジモンを洗脳して使役する、姑息でずる賢い性質を持つ。その姿形とめったに見られない存在であることから、マリンエンジェモンと類似している点も多いが、関係性は今のところ不明である。深海の暗闇のような底知れぬ恐怖のオーラで戦意を奪う必殺技『オーシャンヘル』は、時にこれを受けたデジモンをクティーラモンの傀儡に成り下がらせる。口を大きく開いて鞭のようにしなる三本の長い舌で攻撃する『バッカルラッシュ』と、激しい渦潮を発生させ、ドリルのように相手の身体を削ぐ『アクアグラインダー』は、その小さな体躯からは想像し得ない破壊力を持つ。
