I actually wasn't (though it does fit), I was referencing how, in his own Mythos, Cthulu was basically defeated by ramming a boat into him in a method similar to how Ursala was killed in Disney's Little Mermaid, and how in Fallout, anyone wearing power armor is vulnerable to EMPs.
What? I thought that in the mythos they rammed the boat into him and it didn't do anything?
Mind you, I haven't read it for a very long time, but I thought that it was talking about how it was done it futility, to show how little they really were. Or maybe that's what I just thought would be better.
From what I remember they ram it into him and it grievously wounds him, enough to cause him to have to go back to slumbering at the bottom of the ocean for a couple millenia.
Though, without it directly in front of me I could very well be wrong, and so could you. Maybe we both are, or maybe neither are. Maybe we both were exposed to different interpretation/versions of the same story.
Not quite. Great Old Ones are still world-killingly powerful, they just have a spin-up phase where they have to play by our physical rules for a bit before they get to start slinging all the killer space magic around. Hence the boat thing in Call of Cthulhu.
Plus the whole "go insane by looking upon them and also they literally cannot die" parts, yeah.
there's also a splat race in 3.5 who have heads but don't have necks (their head floats above their bodies via magic) and are thus immune to vorpal weapons.
