They being stronger literaly doesn't matter because they were weaker to the character actualy using the attack, and using "he was barely trying" isn't a good idea because that's literaly the only time the attack was used
"Never dodged" is one but I digress
That's not a NLF, at all, Infinite literal made copys of those characters in the game, even characters he never met (Chaos, Zavok), and the copys have the same powers as the originals, as stated by Silver, and Shadow and Metal do have it in their profiles, and you are underestimating time slow, dodging a bunch of snails when you can teleport is easy, not even talking about how they can just go ham on him before the attack even lands in the first place
No, it was not, because they don't have something like Ki, Metal copied abilities he didn't have, he copied Silver's telephathy, something he himself doesn't have, he copied Chaos Control, something he himself didn't have, this isn't Dragon Ball with a ki energy for every attack, all those characters have their own moves that only they can use, and there's thousands of them who can copy him lol
This doesn't work like you think it does "Well your character can't copy because otherwise my character would" because they have very clear diferent feats of power mimicry and Metal has copied individual special abilities before that he shouldn't be able to in your logic like ESP
It's literaly not a NLF, it's you lacking a clear understanding of how a ability works for certain characters and acting as if it works the same way, there's no accepting it because they are very clear diferent powers
