Wanyamon

Wanyamon is a Lesser Digimon whose name is derived from the onomatopoeia for a dog's bark (わんわん) and a cat's meow (にゃにゃ), and as such resembles a cross between a dog and a cat. It is 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.
