Squids don't need air, but that's because they can't survive outside water for long, because they don't have lungs, so if you go by the argument of "Godzilla can drown" and the Cthulhu's a squid, then Godzilla can just merely kill Cthulhu by getting him out of water and having him asphixiate.

@99.6.210.75 Like I've said a million times now, with size comes gravity, and if Cthulhu is miles big, then it's a physical impossibility for Cthulhu to be faster than Godzilla. Also, what's this nonsense about Godzilla not being "designed to live underwater"? You obviously know nothing about Godzilla, and you haven't read the comments above. Godzilla sleeps and stays in water for decades, so saying Godzilla can drown is not only proof you know nothing about the King of the Monsters, it's also showing you are biased. I won't be some idiot who doesn't recognise the truth--Godzilla can't win against an immortal God, but that's my point, no monster can, and it's only fair to expect Cthulhu to be a mortal creature without God powers or immortality, and in that case, Godzilla can put up a good solid fight and defense against Cthulhu. So no, Godzilla can't drown, and he's very able to live underwater, as has been proven in the films.
