Keramon digivolved straight to Infermon, thus bypassing the Champion level. In this form, Greymon and Kabuterimon had a hard time fighting him. To defeat the powerful Digimon, they also planned to digivolve on their Ultimate Level but while there were digivolving, Infermon attacked them, resulting in their defeat. Infermon then escaped and hacked himself in the US military network, from where he launched a nuclear missile on the DigiDestined. When Agumon and Gabumon attacked him and Warp Digivolved to WarGreymon and MetalGarurumon, he became Diaboromon and in this form he was able to defeat them.

While Beelzemon was testing his new powers on a bunch of Chrysalimon, Calumon's power Digivolved the remaining Chrysalimon into an Infermon. However not even he could bring down Beelzemon, who destroyed him and absorbed his data.
