If Godzilla existed in the Fallout universe, would HE be considered a Ghoul?

Well he technically exists in the Fallout universe in some cameo random encounters

Is there a trait that seperates him form examples of other ghouls?

well Godzilla's enormous size is capable to a radscorpion, radant, or a radroach. 

Radscorpions range from the size of a corgi to the size of a van. Radants are roughly the size of a big dog, and radroaches are house cat-size.

Also like the rad-bugs and ghouls (depending on writer: whether ghouls are solely mutated from humans exposed from a near lethal dose of radiation or if they mutated by a combination of Forced Evolutionary Virus and Radiation) his mutations are radioactive in origin.

So far radiation burn scars, radiation dependent biology, and possible sterility though non-human mutants are capable of reproduction. Although its also hinted that most radioactive mutants in the Fallout Universe could have gain some mutations from exposure to the FEV. 

The Forced Evolutionary Virus is the second source of mutants

Radiation in the fallout universe is extremely weird since its based on 1950s sci-fi, so you get radioactive zombie mutants, giant bugs and giant reptiles

Maybe I should posted this as Godzilla in the Fallout universe

Xenotaris

So could godzilla be called a zombie mutant, Idk much about fallout but Im guessing

But gievn ghouls can be mutated animals and humans I would say goji could be one

well Ghouls might look like zombies but they aren't undead. They are just irradiated humans that merely look like zombies or a burnt person. Cold blooded animals handle radiation differently in the Fallout universe, they grow in size while mammals lose their fur/hair.
