Devil May Cry 3
When Dante enters the Temen-ni-gru for the first time, he encounters a Cerberus frozen inside the tower. The Cerberus, who originally thought that Dante was human, demanded him to leave immediately. But then attacks Dante after being mocked by him. The Cerberus fought Dante with a huge array of Ice attack. He could create avalanches, breathe out ice, create an armor made out of ice, and ram at Dante. During their confrontation, the Cerberus loses two on his heads. After being defeated by Dante, the Cerberus asked his he was human, to which replied that he wasn't sure. After which, the Cerberus respected Dante's power. He then turned himself a Devil Arm, and gave himself to Dante.
- Even though the Cerberus wasn't in Marvel vs. Capcom 3, his Devil Arm form makes an appearance as one of Dante's weapons.
