MC had gamer's body? I didn't notice that. Anyway if you are making him train not just dump stat point then you can make him manipulate his own temprature(of course carefully) to make him resistant to temprature change(he has dragon blood so his body can take more punishment). You can even throw some breathing technique here since according to Iroh fire bending is all about breath(at least on physical side). And MC can develop move like Superman's super flare(expelling large amount of fire from his body in one go). And replicate combustion bending by firing concentrated bullet of chi. You can even turn him into literal living star in later stages by making him turn his chi into not just fire but solar radiation.

Fire is element of strength so maybe user may be able to heal by manipulating 'vigor/vitality/chi' of body. Maybe making it so it takes great deal of stamina of target. You can even make cultivation BS with this just throw some requirment of physical strain on it.

Yes! I wouldn't even complained if it was some BS healing technique. But forming fist of fire just didn't make sense

In my opinion that blazing fist move made no sense in ATLA universe. If it was some western fantsy world it would make sense but it was ATLA, bending is completely different from magic system that has such spell/technique/skills. Chi itself fuels bending, in other word if you used fire bending you are burning chi, which gives no possibly of solidifying fire itself by manipulating chi, since it is burnt, there is no chi in resulting fire, thus it is exactly same as natural fire.

Everyone is mahou shoujo at one point, no matter the gender.

Oh, young one, who has not been enlightened to power of magical girls. What will those characters do against someone who can rewrite reality at their will? Some magical girls are even conceptual beings. Well, Saitama maybe but i'm not sure about other two.

Of course mahou shoujo is ultimate! Majority of most powerful characters are Mahou Shoujo after all.

NOOOO! You can't! It was so cute! I liked this.

So much cringe! I literally dying!

Makes sense considering Reo regained his power thus rendering infinity stones powerless.
