Ryudamon

A Beast Digimon that, because it has an old-style Interface on its brow, is presumed to be an experimental "Prototype Digimon" from before Digimon were discovered. Although its body is clad in Japanese-style armor high in defensive ability, its movements are nimble, so it fights by resolutely leaping into the opponent's chest. It studies the business of combat as it fights, and possesses Bushikatagi, with bravery and a soul that doesn't fear more powerful Digimon. The data that is said to have been hidden within the deepest parts of its Digicore, during an experiment, is the ferocious combat data of the "Dragons" and "Generals" of Japanese mythology, and it is said it has the potential to grow into a mighty Digimon. Signature Move: Withstands the opponent's attacks with its armor and helmet, then counterattacks (Kabutogaeshi). Its Special Move is leaping into the opponent's chest and firing a blade of iron from its mouth (Iaijin).

額に旧式なインターフェースをもつ為、デジモンが発見される以前の実験用の“プロトタイプデジモン”ではないかと推測されている獣型デジモン。防御力の高い和風の鎧を身にまとっているが、動きは軽快で、敵の懐に果敢に飛び込んで戦う。戦うほどに戦いの業を修め、強大な敵デジモンをも恐れない魂と潔さ、武士気質（ぶしかたぎ）を持っている。実験の時、デジコア（電脳核）の最も深い部分に隠されたと言われるデータは、日本の神話における“竜”や“武将”などの猛々しい戦闘データであり、強大なデジモンに成長する可能性をもつと言われている。得意技：敵の攻撃を鎧兜で受けて反撃する『兜返し』。必殺技は敵の懐に飛び込み鉄の刃を口から放つ『居合刃（いあいじん）』。
