Suggested by Sonic Ferham and Vile are both pretty powerful X villains. Vile has more in the way of offensive capabilities while Ferham is a lot more agile. Ferham’s whip could be deadly if it lands, but Vile should be able to avoid any direct hits. His cannons will also take her down before long with a few direct hits. This is a case of speed vs power where the power actually wins this time. Vile wins.
