A Mollusk Digimon of the same species as Numemon. Geremon lacks attacking power but is unusually ferocious, rushing at the opponent no matter who they are. As expected, this obstinate creature will get quickly taken out, but then immediately forgets about its defeats. For this reason, it picks fights with formidable foes over and over again. Geremon uses its special move Hyper Smell to secrete a violent stench from its body.
