Recently I have been thinking about how many people have the belief Aquaman has a weakness to heat. That all it takes is some fire and he dries out and is helpless. I highly disagree with that notion. In fact I believe that it isn't simple heat that bothers him, but rather dryness in particular.

Prolonged exposure to heat blasts from Black Manta only succeed in giving Arthur some superficial burns. And swimming into a lava vent while the Dead King, Atlan melted and Arthur swam out, unharmed by the lava seemed to be no big deal to him. A potassium explosion triggered by Batman didn't slow him down. He has even taken blasts from Neutron, who is essentially a walking nuclear reactor.

And there are other ones that I didn't even include that show Aquaman not being bothered by heat. His one bad desert experience couldn't have been due to the weather alone when Arthur has been exposed to higher temperatures and been just fine.

He is pretty much as durable as Superman and Wonder Woman the only weakness I see in him is water deprivation.

@justthatkid: I didn't mean in the sense that he can't be harmed by heat. That much was proven by the Black Manta scans. My intent was to prove that just hitting him with it isn't going to start drying him out and render him ineffective, which is a belief many have.

Also the volcano god should logically be hotter than normal lava. And it should also be well into the heavy hitting league since it presented a huge threat to Arthur. I just don't think fire itself is a weakness to him.

True, true. Karaku is the size of a mountain. So that much force is clearly gonna hurt. And it definitely seemed to hit him harder than anyone else he has fought. Not even Atlan beat him up that badly.

And the "he's a god" argument is laaaaaame. I can point out plenty of fictional gods who got rekt by humans.
