It’s true

Godzilla can lose to Bill. His answer is my answer.lol

Bill might win, but it depends on what Godzilla. If it’s IDW Godzilla then it’s 50/50. If it’s Heisei Godzilla then it’s also 50/50. Every other Godzilla might lose.

No, he is unkillable; the only way he died was from a memory wipe. So the only Godzilla to kill him is a mind Godzilla, and there is no Godzilla like that

Godzilla might not be able to kill Bill, but Bill can’t kill someone who cannot die. And Bill can’t psychically manipulate Godzilla because he can’t be reasoned with or controlled. So the fight would last for eternity.

And erasing Godzilla wouldn’t work either because Godzilla has died multiple times and came back right after. And Godzilla has faced and killed God.

BUT Bill was summoned by Gideon, which is how he entered Stanley's mind. All someone needs to do is reason with Bill to kill Godzilla from the mind, and boom. And although you're right, there is only one Godzilla that he can kill, and that's the first Godzilla. Bill is shown to manipulate time and space so there

Bill can make a deal with someone to invade Godzilla’s mind, but Godzilla’s mind is pure chaos and rage, and Bill can die inside someone’s mind, so Godzilla would be able to kill Bill in that situation. And manipulating Time and Space would have little to no effect in Godzilla’s mind, and Godzilla has survived Time and Space based attacks and a laser that killed 95% of all life on Earth with no damage and an asteroid directed at him with no damage either. Bill could erase Godzilla, but it would only be a matter of time till he returns stronger than before.

But remember, bro can only lose if he is erased, and he can change the mind, mind manipulation, remember. Plus, he could just trap Godzilla in another universe, counting as a beat.

Also, he DISINTAGRATED TIME BABY. DISINAGRATED

Godzilla survived being in The Underworld, a black hole, and the vacuum of space. so I think he can survive in any environment. And Time never stopped Godzilla, he’s immortal. And you can’t alter the mind of a beast who represents “Force of Nature”, he is also bound to his duty to protect Earth from any threat, no matter how big or powerful. And it’s quite easy to anger Godzilla, and anger makes him stronger and more wild. Chaos is almost impossible to control or erase.

Godzilla can also regenerate from just a single molecule, he also gets stronger every time he regenerates.

but he also can alter the world and I know he can grow and alter his look

you know what im gona do something

Indeed he is undefeatable. He's the King of all Monsters.
