jonny going to sun like temperatures is not happening. going that far often leaves him on a near death state and with his average flames even spidey can kick him.
He's faster, and he's destroyed large asteroids, heat isn't his only strength, he has pretty good destructive capacity too. Also he's taken hits from Marvel class 100's on a regular basis, and went on fighting like it didn't happen. You guys really don't know all that much about Johnny if you think he has to be bloodlusted to go nova level flames, or that he'd be "left in a near death state" lol, watch and learn, here he uses a focused nova intensity blast on Iron man, of course Iron Man is too powerful for that to work on him, but Natsu is no Iron Man. The other scans show him using planck temperature, and yeah he probably would need to be bloodlusted to use that kind of heat
I didn't know about that feat. So now he has Absolute Hot hype? Interesting. Although it doesn't make sense to me in the grand scheme of marvel flame users that are supposed to be stronger than Torch but can't hit that temperature.
I didn't know about these feats 8 months ago myself apparently looking back on my posts in this thread, I thought Johnny couldn't use Nova intensity heat without Susan around, and I thought he had to have the cosmic control rod to use supernova level heat as well, but I was wrong, you can even see Johnny stating he's at supernova level heat right there in the picture.
About the other flame users stronger than him thing, yeah it is kinda weird that they haven't been shown to reach those heat levels, but I guess they just have way more destructive capacity than he does, Firelord for example is a casual starbuster. Also there is a scan of Reed stating that Johnny knows more about heat than anyone he knows, that could play a role in his temperature manipulation I guess
