So many people love to use this idea of Fox Apocalypse reacting to quicksilver as a feat for other speedsters not being able to blitz him. But that isn't what actually happened. He was getting dominated and then he sped up his perception time to be able to track quicksilver. He doesn't start off anywhere near quicksilver level reactions. The only thing that saved Apoc was Quicksilver's piss poor striking abilities. So please stop using it as a game changer feat.
