Again, it's not accepted/on pages yet, so it's just for the fun of discussion.
I prefer keeping it anyways , there's no point in this match if the CRT is gonna delete it. I'll keep this argument so that way
Basically, Reinhard can beat the soul of the world itself in a fight. This soul of the world is the Od Lagna, and is the one that grants his Blessings, but it's also an existence that partially exists as a different, endless white dimension where souls get cleansed for re-use. This Od Lagna is also one of the entities that view the world as a mere play or game, and control all of fate at will.
Ah, I see why this can be a contentious thing, it's "partially" a dimension so Rein could just be hitting the part that isn't a dimension too
But for sake of simplicity I'll just say Rein can hit 4D structures. I'm still doubtful about the whole thing him discovering an entirely new subatomic particle because he needs to, just because he can answer tests intuitively (which at least have documentated answers), just by seeing light holograms
All of that including the fact that Prevasion can defend from a multiversal attack instead of a universal one like what seems to be the case with Od L.
In addition, GV can mix up the type of Prevasion he can do. He can transform into electrons, radio waves, EM Waves, electronic data, electricity on its own etc. And Rein would have to adapt to each one before GV tries a transmutation or a more likely two new arguments I just came up with
Let's hypothetically say that Reinhard sees GV just standing there and somehow figures out by him just standing there that he can turn into all those specific types of things with Prevasion and also that he can see the High G Regen so he needs to knock him out, just by GV standing there- and he does it
Lumen (whose with GV 24/7, and is part of his powerset) has a history of bringing back GV when he's going or about to go unconscious , she can just activate Anthem right there and GV will be back up on his feet. From there, GV can do an actually very likely move which is use his Class P Electromagnetism (might be 4D since it can control another magnetism ability that has 4D stuff) to trap Rein in this massive EM Field and crush or tear Rein (only Class T) pretty much instantly- the range would be big enough to bypass any skill gap. In fact GV can do this right off the gate. Even if Rein survives for a moment teleports out, GV has a Passive EM Field around him at all times, and since Rein is a Melee fighter, he'll be caught again. And if Rein goes ranged, GV can teleport of the way of ranged attacks back into close range (or long range if he wants to), up until GV goes Primal Dragon and the radiation takes effect
The second option is more unlikely than the Transmutation, but it's worth mentioning. Lumen's mind manipulation can be interpreted to be even better than the Dragon Radiation
I should also mention it's not specified how long GV takes to become a full Primal Dragon. It could be long enough for GV to do the above I just mentioned but also enough time for Rein to figure him out, or it could be short/instant enough for Primal Dragon GV to come out before Rein can figure out he needs to knock the dude out before he instantly goes berserk kill mode from the radiation
