User blog comment:GodzillaIsland7.2/Which Characters Do You Think Godzilla Should Lose To?/@comment-3367060-20130914210200

Godzilla could beat the original Cthulhu which was killed by a boat and was mortal, but he can't kill the Mythos Cthulhu. But, could Godzilla kill the Devil? In the misconceptualized film (TY TK), Satan was the bad guy so Godzilla would have surely killed him, but since the film was just that, then I think he wouldn't win.

I agree with GodzillaIsland, but I shall do some creative picks.

Superman is one of the characters that can pop up often in this question. At first glance, Superman could easily beat Godzilla, right? However, a few little details could make it so these two could battle for ages, but one could argue that Superman is the good guy so he always would win, but maybe you should dig deep into Superman history. In a recent animated feature film where Batman is kind of an old man, Superman is actually an anti-hero, as he is the United States goverment's pawn, and he is sent to knock some sense into Batman, but Batman surprisingly defeats Superman (with help of Kryptonite, but it counts!), so Superman COULD be a bad guy in a Godzilla vs. Superman scenario, so maybe not Superman.

Batman would have probably been the protagonist of Godzilla vs. Batman so it's reasonable to think Batman could beat Godzilla (How? That's anyone's guess).

There's also some insane probable matches like Godzilla vs. an Optimus Prime that is not the G1 incarnation. Not only would the non-G1 Optimus-es be the hero, but they would have loads of powers and advantages which could really help against Godzilla (at least the overpowered incarnations of Optimus anyways), so Godzilla could lose against Opteemoose.

Godzilla vs. Goku could be interesting, but even though Goku is always the hero, he is much weaker than Superman and has humanly weaknesses that Godzilla could easily reach, so Goku is probably not a realistic choice.
