Suggested by Sonic Duel Sieger is a very powerful monster and one of the more powerful ones in the whole world of Buddyfight. That being said, he’s not going to quite be a match for Chaus here. Crossfusion gives Chaus access to abilities beyond any monster and his Protoman was already a super powerful ally. Duel Sieger doesn’t have the speed to keep up and will quickly be taken down for the count because his defense is not enough to survive the attacks for very long. Chaud wins.
