Atamadekachimon

A Dinosaur Digimon with an unbalanced head and body. It is always having difficulty walking due to its heavy head, and completely destroys things when bashing its head about, even if it means no harm. It hates fighting, and is very motherly, constantly worrying about Minidekachimon, who it raises and protects within its mouth. It talks so loud that even Minidekachimon has to cover its ears, and gets even louder with the "dekaa" it attaches to the end of its sentences. When Minidekachimon runs into danger, it fights for its life. It restrains the opponent's movements with its "Tsudzumi Bakusai", in which it raises its loud voice to maximum volume, and seizes the opportunity to crush them with its "Atama Tsubushi", where it swings its head down from above with all its might. It also cooperates with Minidekachimon and spews flaming breath from its mouth in "Minideka Flame", but it is uncertain whether the flames will be small or large until it comes out.

頭と体がアンバランスな恐竜型デジモン。いつも頭が重く歩きづらく、悪気は無くても頭をぶつけては器物を破壊してしまう。戦うことを好まず、母性に満ち溢れており、口の中で育て守っているミニデカチモンをいつも気遣っている。ミニデカチモンでさえも耳をふさぐほどの大声で喋り、語尾につける「でかー」でさらに大声になる。ミニデカチモンが危険な目にあう時は生き延びるために戦う。最大ボリュームで大声を上げる『鼓・爆砕』で相手の動きを牽制し、その隙に全力で頭を上から振り落とす『頭つぶし』で敵を押し潰す。ミニデカチモンも協力し『ミニデカフレイム』で口から火炎の息を吐くが、火炎は小さいか大きいかは出してみないと分からないという。
