Cthulhu vs Godzilla would make a good movie fight. While Godzilla is marginally larger, possesses rapidly healing G-cells, and had the abillity to shoot both fire and atomic breath - Cthulhu is the herald and preist of the Great Old ones (one of which being neo-satan, another the essential ender of the universe, and one of which pretty much is the universe. Though he doesn't really have any powers beyond being big, sanity blasting, and is able to fly through space, he has non-solid biology that reforms indefinately and essentially instantaneously (even from an Oxygen Destroyer, say). I think in a movie though, Godzilla would have to win - if just for the fact that he can hold out long enough for the stars to change, and Cthulhu have to flee.
