Yeah. He was defeated by a steam boat in his first appearance which cut him in half IIRC. One could argue that he wasn't at full power, but still Cthulhu based on that has either horrible durability or is weak as all high hell when he wakes up compared to Godzilla whole can tank entire armies and monsters right after waking up.
