Culden was seen to fight and launch several punches to High Priest R. Seeing that the high priest's headgear was broken, Culden was surprised that R also had canine ears. He then encountered Baylord Paul who asked about his rankings in The Cage. After hearing that Paul's wanted to kill every leader in The Cage, Culden quickly transforms into his second stage transformation to fight Paul. However, because of Paul's status and strength as a high ranker, Culden was defeated easily. His transformed body was torn apart and then he fell to the ground. It's still unknown whether he's still alive or not after the attack.
