Infermon

Infermon is Ultimate form of Keramon.

Digimon: The Movie
Keramon warp-digivolves to Infermon in response to Agumon and Tentomon digivolving to their Champion forms, and at first, the DigiDestined assume Infermon is only a Champion Digimon. Izzy realizes they were mistaken when Infermon quickly overwhelms their own Digimon, and the children attempt to digivolve Greymon and Kabuterimon further to their Ultimate forms; however, Infermon shrewdly attacks the Digimon while they are still in the process of digivolving, incapacitating them so it can escape.

Infermon then locates and hacks into a US military network, from which he launches a nuclear missile strike on the DigiDestined: one at Willis's location, and one at Highton View Terrace. He is swiftly tracked down by WarGreymon, MetalGarurumon, Tentomon, and Patamon, but just as he seems to be on the verge of defeat, he digivolves once again, to Diaboromon.
