A gigantic Demon Dragon Digimon which possesses eight heads. However, while there are eight heads, seven of them are dummies, and the black head in the middle is the only real one. Orochimon's origin is ancient, and even in the Ancient Digital World its menace was a thing of old, so a certain area was driven right up to the brink of annihilation until Orochimon was sealed by the tamer of an "existence", who was trying to preserve the harmony of the Digital World. Its Signature Move is to make the opponent completely drunk by intoxicating them with its alcohol-laden breath (Sake Breath). Its Special Move is to make the tip of its tail become as sharp as a sword and then cut up the opponent (Ame no Murakumo).

８本の頭部を持つ巨大な魔竜型デジモン。しかし、８本ある内の７本はダミーであり、中央の黒色の頭部が本体である。オロチモンの誕生起源は古く、古代デジタルワールドでは猛威を古い、あるエリアを壊滅状態にまで追い込んだことがる程の存在だったが、デジタルワールドの調和を保とうとする“存在”の使いによって封印されていた。得意技はアルコールを含んだ息で敵を酔わせて酩酊させてしまう「酒ブレス」。必殺技は尻尾の先が切れ味の鋭い刃になり敵を切り裂く『アメノムラクモ』。
