Raven Branwen is an incredibly powerful fighter and already was a big threat before she became a Maiden. While Unalaq could have potentially given her a good fight before that, now he stands no chance. Even his Dark Avatar form wouldn’t be able to keep up with her abilities. She would be speedblitzing him throughout the whole fight and he would have a tough time getting in a hit. They’re just in different leagues. Raven Branwen wins.
