This is not stopping time, this is reacting and blocking Kakyoin's
danmaku. Despite both fighters/attacks being similar if not equal speeds, he handled the sheer amount of projectiles with little difficulty. I have my doubts a couple of chains are going to be a problem for him just because he launched them on an angle. He just sidesteps and grabs it.
That's... not what I'm comparing? There's an upper limit to how creative and trained you can get when launching your spear chains out of your arms. His experience means nothing in overwhelming Dio in that aspect. What, is he going to make the chains do a couple of twirls, stop for a second then continue, grab a cup of coffee and THEN hit Dio? Of course not, he's going to make them lunge towards his opponents center mass,
as displayed in every single iteration of Mortal Kombat. So yes, any reasonable athlete or rugby player can dodge or evade the spears given a fair distance (assuming speed equal)
That's great I guess, the moment Dio catches the chain he's going to be freezing Scorpion entirely. From there the fight is as good as over; Scorpion can teleport away but Dio is still going to be connected to the chain so he still freezes.
You know, feats aren't impressive without context. I pressed a button on my desk. It nuked an army of 8-A fighters. I guess I am now comparable to 100+ 8-A fighters in terms of skill, right? I'll wait till you actually source your argument for once.
According to the Mortal Kombat wiki, Sub-Zero uses a flash freeze process to create his ice and ice blast attacks. His ice has demonstrated the ability to nullify or counter Scorpion's hellfire. Dio uses an
identical process for his vaporizing freeze.
(This is the chapter you want to check out if you wish to read more about the ability.) Therefore it stands to reason his vaporizing freeze (which freezes parts of his own body) is comparable enough to Sub-Zero which can withstand Scorpion's flames.
