Gigimon

Gigimon (ギギモン)
A four-legged Baby Digimon that grew from Jyarimon. Its physical features resemble those of Tokomon, and there are powerful fangs growing within its mouth. However, unlike Tokomon, who evolves into the Mammal-species, Gigimon, who evolves into the Dragon-species, has a rough personality, and is ferocious despite its small size. There are more than a few even larger Digimon that were deceived by its appearance and suffered a counterattack. Its Special Move is snapping at the opponent (Hot Bite). Its temperature is hot like with Jyarimon, and it is said that it burns the things that were bitten.

Etymology
Gigi: From gigi (疑義), meaning "doubt".
