Natsu Dragneel VS. Shiki Granbell

[Saqphire]

Now that Natsu has finally caught up with his compatriot Shiki in scaling, it wouldn't be more than right to have their first battle against each other.

Battle Rules
Attack Potency: Both keys with Low 2-C - Universe Level+ scaling (So Universe Zero Shiki vs. Savage Dragon Flame Natsu)
Speed: Equalised
Location: Neutral planet in Edens Zero's cosmology, where they stand 10 metres away from each other
Win Con: Death or Incapacitation
-
Scenario: Mashima ends up merging both universes once again and this time, because of an off-screen scenario, they find both Rebecca and Lucy who appear to be dead. They both believe one killed the other's woman and because of this misunderstanding, they end up duking it out.
Knowledge: They know who they are from HERO's, and as such they know what their abilities do.

Space Natsu: Lynieryz, Steve1775
Magic Shiki:
Inconclusive:​

 

[Lynieryz]

True Gravity stomps? Everything Natsu does will simply be conceptually absorbed and L2-C BFR instantly ends the fight.

 

[Steve1775]

Is Natsu 200 million degree Celsius flame passive?

 

[Saqphire]

Is Natsu 200 million degree Celsius flame passive?

In SDFF, it is

 

[Steve1775]

In SDFF, it is

So, then Shiki then. His powers are far more versatile

Natsu got CM2 for the gravity iirc

Natsu CM2 is specifically for time, it won't prevent the flames from being conceptually absorbed.

He also used SDFF against Acnologia who had space-time magic and magic immunity, so I think it's just power null overall

Okay? That doesn't prevent it from being conceptually absorbed unless you're arguing that his CM should extend to magic, which isn't currently accepted on the Wiki.

200M Kelvin comes from Wall using nuclear fusion and Natsu's flames being hotter than that.

Shiki survived particle antiparticle annihilation in far more massive quantities when he was infinitely weaker, back when he would've gotten curbstomped by any OSG. (Btw in equal masses, heat&radiation from annihilation >>> that from any nuclear fusion)

And while Natsu's scales extends from Nuclear Fusion, even far more impressive, Shiki's heat resistance extends to Temperatures very very very shortly after the Big Bang (when the universe was super super compact) as he condensed it all into his body and withstood it. Plus, radiation in early Universe when dark energy was insignificant would've been much lower than Chronophage Big Bang
