Suggested by Sonic Revy is super skilled with a gun and could hold her own with Vash in terms of accuracy. That said, what will end up catching up with her is the fact that her weapons aren’t at as high a tier as his. Vash’s cannon could easily obliterate her with one hit and has a large enough range to make it happen. Her speed just won’t be enough to stop him here. Vash the Stampede wins.
