Wanyamon

Wanyamon (ワニャモン)
A Digimon fused from the data of small, pet animals like dogs and cats. Because its unexpected movements are also quick, caution is necessary so that it doesn't get away, but it becomes very emotionally attached if shown affection like a pet. Its Special Move is suddenly biting, after appearing amply charming (Smile Fang).

Etymology
Wan: From wan wan (ワンワン), onomatopoeia for the sound of barking. Nya: From nya nya (ニャア), onomatopoeia for the sound of meowing.
