Raven has some impressive shadow abilities at her disposal which will help her in this fight. She can throw a lot of debris to try and slow Raven Branwen down. It’s not going to be enough to stop this bird though as Raven Branwen can just incinerate everything in her path. She also has the massive speed advantage and can quickly just hit the teen with her power palm. The sheer impact from that ability sent Cinder over the edge afterwards so I wouldn’t doubt its power. You just can’t stop a fighter who is this fast. Raven Branwen wins.
