Considering MEGA's manipulation of electromagnetism is completely psychic and can attack internally, is there anything preventing him from just... bypassing the armor around his body?
Well, it has NPI, meaning it can interact with incorporeal forces and whatnot. In fact, it can even absorb and seal powers.
Also, is there any smurfery / layers attached to that resistance? MEGA's electromagnetic powers have been able to bypass/ignore/overpower various forms of resistance.
Well, it ignores all forms of resistance, obstacles, etc. Unless it encounters a power of equal magnitude, but that would require something a Meta-Layer above Supra.
As great as that sounds, Reincarnates in Ark are likely completely immune to it by virtue of their Type 2/4 Acausality, which makes them cosmological singularities. There is no predetermined future or past regarding their existences. You wouldn't even be able to see them in the future, nor anything that would be affected by them. It is to the point that even if you were to invent your own directions of time which ran perpendicular to normal time, they would still be a singularity upon that new axis.
Funny you mention that, because the [Seal of Reincarnation] is specifically able to view the past and origins of someone, even if they have no history of reincarnation.
They essentially only possess their own, subjective axis of causality that constantly changes with them. Which is distinct from the structure of the universe entirely. So trying to use precognition, time travel, time manipulation, etc—is basically completely useless.
Su Zhou is similar, yet even his seemingly non-existent fate is still part of a grander fate. Even free will itself is part of fate. Best quote I can find to describe it.
Fate is what must happen. Fate is irresistible. Fate is now, the past, and the future-not immutable, yet even change itself is fated. No living being escapes destiny, no matter how humans rage against the heavens declaring "my life is mine to command." Fate remains. For shouting, indignation, and rebellion against fate-these too are absolute destiny. Conversely, if one insists life is inherently free, that freedom of choice is absolute... then isn't free will itself a form of fate?
As for analytical prediction types, MEGA has similar levels of scaling. If this becomes a skill debate, we might be here for a long while.
The most basic stuff I could bring up is that an inferior MEGA to the one in this key is already at the level, where, if you aren't planning thousands of actions ahead in battle, you instantly lose the fight. It's to the point that characters are described to be fighting against "thoughts MEGA had thousands of moves ago." He also has enough processing power to predict a literally infinite amount of clones attacking him from across space and time simultaneously. With each of those clones being a copy of a character named Myrme, who herself is ridiculously skilled. Like, predicting attacks that time travel across years type of skilled.
I don't mind turning this into a skill debate.
Su Zhou has reached the point where he can unleash [Perfect Strikes], attacks capable of shattering all obstacles, including space and time themselves. Even if his strike clashes with another attack designated as the “Protagonist” of fate, Su Zhou’s Perfect Strike will simply be reborn infinitely, growing stronger each time until even the force that initially stopped it becomes ineffective.
So essentially, Infinite Reactive Evolution on an attack. This is one of his smurfier abilities, mind you.
Also worth noting that he grows at an absurd rate in battle as well. He can go from being drowned beneath someone else's premonitions to absolutely rocking their shit in just a couple of strikes. He also has that crazy Saitama-ahh type of evolution where even if you copy him he just exceeds the copy anyway. And even if you grow at the same rate as him, his rate of growth itself also exponentially grows until it overwhelms yours.
Su Zhou possesses several techniques specifically designed to counter opponents who rely on RE.
The first is his Divine Staff, which accelerates and refines an opponent’s thoughts to a supernatural degree, forcing them into a constant state of enlightenment. However, this enlightenment becomes a curse: their mind is pushed to such extremes that they begin overanalyzing everything, even trivial matters, until their focus collapses under its own weight.
The second is a sacred flame that ignites and consumes all latent potential within the target, forcing them into an endless cycle of evolution. This uncontrolled development rapidly deforms them, accelerating without limit. Any power to resist the evolution merely becomes additional fuel for it, until they are just reduced to ash.
