Devil May Cry 3
When Dante enters the Temen-ni-gru for the first time, he encounters Cerberus frozen inside the tower. Cerberus, who originally thought that Dante was human, demanded him to leave immediately. But then attacks Dante after being mocked by him. 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, Cerberus loses two on his heads.
After being defeated by Dante, Cerberus asked his he was human, to which replied that he wasn't sure. After which, Cerberus respected Dante's power. He then turned himself a Devil Arm, and gave himself to Dante.
- Even though Cerberus wasn't in Marvel vs. Capcom 3, his Devil Arm form makes an appearance as one of Dante's weapons.
