Tentomon is a type of beetlelike Digimon which dwells in the forests of a strange digital plane. Far less aggressive than the other monstrous arthropods which call such forests their home, these Digmon are carefree and friendly creatures which can defend themselves with electrical powers. Inquisitive Insect. In some ways a Tentomon resembles a monstrous, vaguely humanoid ladybird slightly smaller than a halfling adult or a human child.
