Yeah. Natsu ate Dark Regulus and added it to his own flames like Laxus’ lightning and LFDM.
From Natsu’s profile
From Loke/Leo’s profile
My only guess for why the absorption for BFDM isn’t on Natsu’s profile is cuz it is technically already accounted for earlier in the profile where he can absorb fire, lightning, ethernano, all of the elements that make up Etherion etc.
BFDM > Base Second Origin >>> Key of Starry Heavens > X784 Zancrow = vaporising rock = 3000 C
For cold resistance, this Natsu is chilling in the middle of a Mt. Hakobe blizzard which is cold enough to the point of his flames being incapable of melting snow right next to it or being in direct contact with Natsu’s body.
Happy also considers these flames (while nerfed by the cold) hot even though not long after this, he is in the centre of Jackal’s explosion and comes back just fine beyond fuzzy hair and some soot. Temperatures at the centre of explosions seem to be around 3000 K according to a quick search.
I mean, that just says it absorbs light? That doesn’t mean he could just absorb a Kamehameha because he can suck up light. The actual attacks should not be affected unless Shoto’s Phosphor is purely light based, which it isn’t, it just kinda gives off pale light. So a description like “capable of absorbing light” should not mean “anything that produces light gets immediately negged.” I’m gonna need more context on what it actually does.
Where did vaporizing rock come from? And if that’s how hot it is, it’s really not impressive. Dabi was going to burn away, to literal nothing, 5km worth of area that included rocks, but Shoto shut him down. Like I said, baby Dabi was already throwing around 2000 degrees Celsius without any flashfire fist.
Also I completely forgot Dabi’s second best temp feat: he turned Best Jeanist’s carbon fiber wires to ash.
Shoto’s Final Phosphor > Dabi right before he goes Supernova (temperature VASTLY increasing every single second until he would explode) >>>Dabi’s Initial Phosphor > Shoto’s Phosphor > Named Flashfire Fist Moves > Dabi’s Flashfire Fist Aura = vaporized/turned to ash Carbon Fiber = 4000 degrees Celsius.
There’s also Endeavor’s Prominence Burn feat where he destroyed superheated Plasma clones, with Plasma reaching temperatures of 6000 degrees Celsius. Which Dabi would massively scale over.
IDK what explosion you’re seeing that is 3000K at the epicenter, explosions vary a ton. And 3000 Kelvin isn’t even impressive, that’s like less than 3000 celsius
