Atamadekachimon

Atamadekachimon is a Dinosaur Digimon. Its head and body are unbalanced. 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, its pre-digivolution 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.
