Cerberusmon

Cerberumon
Cerberumon is a Dark Animal Digimon whose name and design are derived from the mythological Cerberus. It is referred to as "Cerberusmon" in American Bandai materials and Digimon Data Squad. It is called the "Watchdog of Hell". The claws on its feet are hard enough to easily tear through Chrome Digizoid alloys, if they have a low purity. Also, its body is protected by a hard living shell, which has the ability to instantly repair any damage it incurs. The armor on its shoulders each possess sentience, and are able to instantly sense an attack coming from any direction, then report it to Cerberumon's central body.

Digimon Data Squad
When Marcus Damon, Thomas H. Norstein, Yoshino "Yoshi" Fujieda, and Homer Yushima were tied to posts in the Holy Capital's Arena, Baromon unleashed a Cerberusmon on them. Kamemon freed their Digimon whom attacked Cerberumon and freed their partners. Cerberusmon dodged Marcus's punch and ran towards Yoshi who fought him bullfighter style. This gave Marcus the opportunity to punch Cerberusmon. When Marcus was about to digivolve Agumon to fight Cerberusmon, Baromon spared them when he discovered Marcus' connections to Spencer Damon.
