A Digimon who resembles an ancient dinosaur that existed in the prehistoric world. It has developed two arms and sweeps everything down with its enormous tail. It is intelligent, and because of its obedient nature it is very easy to handle. Because of that, it is convenient for beginner tamers and is often brought up with care. Its existence is said to be typical of the most basic of Digimon. Its Special Move is spewing deep crimson flames that are the same color as its body (Fire Breath).

有史以前の世界に存在した古代の恐竜のようなデジモン。発達した２本の腕と巨大な尾で全ての物をなぎ倒す。知性もあり、おとなしい性格のため、とても手なづけやすい。そのため、初級テイマーからは重宝がられ、だいじに育てられることが多い。もっとも基本的なデジモンの代表的存在と言えるだろう。必殺技は身体の色と同じ、深紅の炎を吐き出す『ファイアーブレス』。
