Kabuterimon

Kabuterimon is an Insectoid Digimon, whose name and design are derived from the Rhinoceros Beetle (『甲虫』). He has a hard exoskeleton that gives him iron-like defense, and his jaws possess ant-like strength.

Our War Game
Tentomon digivolves into Kabuterimon in order to defeat Keramon, who then digivolves into Infermon, skipping the champion stage. The Digi-destined do not realize this until after several of their attacks cause no damage to Infermon. Kabuterimon then attempts to digivolve to MegaKabuterimon, but is attacked while digivolving and instead regresses to Tentomon.
