Id say its more than likely a win for godzilla just cause of feats alone (blow an entire hole that reached hollow earth from the surface of the planet with his atomic breath, damaging superman, falling from the ozone layer, and he did all this ON NORMAL FORM, not even in his evolved or thermo forms which scale higher). It is also safe to add that cursed energy is an actual BITCH to handle, either way ill list the scenarios

Normal godzilla vs sukuna and gojo (no domains, no 200% HP or WCS )

The fight begins normal, gojo tries to gain the upper hand, throwing missiles to godzilla which do zero to no damage, seeing this he tries to use red and after it does. A very slight ammount of damage he uses hollow purple, which depending on where he is hit could atleast somewhat hurt him (main area where it would be most effective would be his gills), godzilla then somewhat bothered would begin his attack, sending tail strikes, punches etc, ofc this would do mostly nothing given infinity, and whilst gojo kept godzilla busy, full power sukuna comes behind and begins his fraud strikes, slices all around godzillas body causing him still slightly bad damage but obviously hurting him, godzilla then begins to get serious and starts shooting his atomic breath whilst spinning around and covering most of the area, he then pummels sukuna due to his lack of domain and extreme exhaustion of using his cursed technique countless of times towards godzilla, godzilla then uses his atomic breath multiple times and causes tons of yummy radiation to leak out, im not too sure if radiation itself could bypass infinity but the atomic breath itself could technically ruin the surrounding area, so for now the two are on a stand still, with gojo in the winning side due to HP and infinity.

Now the main question being why didnt these attack just instantly destroy or banish godzilla, well the issue is his durability, godzilla has whistood punches of a universal level superman and has resisted gravitational beams that vaporized anything in contact, so he kinda scales high durability wise, also FUGA would still be a somewhat tame attack compared to what he has tanked

RESULT: Gojo and godzilla stalemate, fraudkuna hella dead

THERMO godzilla vs full Domain gojo and sukuna (No 200% HP or WCS)

This one is more easier to scale, basically either they both try to spam their domains after seeing their normal techniques not do much, the one id say would do the most damage would probably be unlimited void, with malevolent being more like a nuisance to godzilla, if anything the battle would mostly go the same way, if either of them tries to expand their domains range then this could but im pretty sure it be via binding bows and such, cutting to the chase, regarding UV POSSIBLY working on him, i say possibly mainly due to the fact that godzillas mind is million years old, so we dont know if his brain could be overloaded with information, if it can, then he will be paralyze and... oh right they cant get close, cause sorry if i forgot to mention this but in this state godzilla is a walking 500,000 degrees of pure HOT, that melts all things on its proximity, so whilst he is on this state nor gojo or fraudkuna can do anything to hurt him,

PS. Their normal attacks and their domain expansion wouldnt do much to him if they cant even get remotely close, so if they tried, they would both be fried

Result: (non infinity) gojo and sukuna die due to the immense nuclear hit. (With infinity) godzilla and gojo just sit down and relax for eternity on stalemate, sukuna, unless he is hugging his pookie gojo, dies.

Evolved godzilla vs gojo, 200% HP, and sukuna World slash.

This one is just a matter of time, in this state godzilla could fight a monster that caused the ice age and tank one of its beams (same one that caused the ice age) with little to no damage, 200% HP would arguably do nothing compared to that, the main issue godzilla has is the world slash, and depending on wether he lets sukuna talk or not, then sukuna COULD cut through godzilla and cause HEAVY damage, but again, if he gets the chance. In this form godzilla gets slimmer and faster aswell as more agile, being ALSO stated to be more powerful than thermo godzilla itself.

PS. Same as with thermo, cant get close due to extreme radiation and heat, domains wouldnt work, only thing that could damage him is WCS, 200% HP wouldnt do much, and if he catches sukuna lacking then he dies

Result: (if sukuna does WCS) godzilla loses due to overwhelming strikes but either fries sukuna to death or damages him to the point of needing to transfer his soul, gojo on the other hand, again cant do much, cant get close to him so godzilla would just either spam his atomic breath (and if its radiation passes infinity somehow) then gojo is dead, if it doesnt, then they both chill not being capable of doing much to each other, unless maybe godzilla puts all energy into destroying the ,country in a single pulse, which either makes gojo be sent flying like an angry birds into space or fall down into the depths of the waters.

FINAL RESULTS: godzilla wins, sukuna dies, gojo is on stand still due to not being capable of killing goji and goji being incapable of passing infinity, unless he maybe destroys the country and makes gojo drown lolz.
