That is also a good question, though from what i've seen of godzilla content over the years, I was assuming regeneration far above human standards, but with some kind of limiter [like rapid regen but with an upper limit, or a simply impressively high rate that doesn't constitute invincibility.] were a given for most of them in some form or another.
