Originally posted by xJLxKingNot necessarily, in comics your reach a limit were said characters shows no need to use speed or speed is pretty much irrelevant. Yes that slower character hit faster characters for sake of the story which is often the case for someone like Hulk who has been shown inability to tag fast moving object. But there is always a lot of evidence supporting that that character can indeed be speedblitz and if speed is used on them they won’t be able to react. Which isn’t the case for Thanos has stopped speed blitz from the Fallen One before.
Thanos tagging SS, Thor and others is no different. He tags them because of the story. In Kmc, characters fight to full potential and they aren't slowing own for the sake of the story. If my interpretation of the rules is right, Superman will be moving at nearly top speed, but still within his CIS
You have to ask your self have you ever seem Character above or at sky father level use Speed in battle? hardly happens IN comic books and they usually own characters who have FTL reactions.
