Write Thanos name in the Deathnote while he's wielding the Infinity Gauntlet

Would he die or would the snap kill you before he is aware.

Comic Thanos? He has a heart attack but doesn't care. Not long after, it starts up again, assuming it even shut off in the first place.

Dude has ABSURD durability, eternal heritage and control over his own molecules and can even overcome reality warping esoterics. He should be fine without even needing the gauntlet.

MCU Thanos? I dunno, he probably starts dying of a heart attack but then either cures himself with the IG or snaps you for a mutually assured destruction tie.

Isn't the Death Note only against humans?

[The Dog]

Would he die or would the snap kill you before he is aware.

Comic Thanos? Ryuk (I assume he comes with this Death Note) tears the page out before you finish writing and eats it before telling you if you try again he'll kill YOU. Remember, Comic Thanos with the Gauntlet basically defeated every cosmic-level entity in his universe and even Death herself acknowledged he was far above her in power.

Isn't the Death Note only against humans?

Explicitly so, yes. It won't do anything to Thanos.

[JohnDiggle]

MCU or comic Thanos either is fine.

[Slade1]

Thanos with no powers at all would still win.

Explicitly so, yes. It won't do anything to Thanos.

I'll admit it's been a very long while since I last watched the series but I don't remember it being explicitly mentioned that the Death Note only works on humans.

Literally Rule #1 in the Death Note is “The HUMAN whose name is written in this note shall die.”

As I recall, they don’t work on the Shinigami and so in the absence of feats, the Death Note isn’t working on Titanian Eternals.
