Power Cannon is magical. That said, Ana's physical isn't completely horrid (Well, above the 25% of Ana's MHP Beowulf would be draining back), if you were inclined to not see any of Beowulf's relevant stuff as hitting on turn 1. Of course, I feel like in this case, Beowulf might just twink for HP and have a chance to OHKO her with Shock. He probably misses the OHKO to most averages, and might even to my slightly lower one.
