Exactly. Zeus is nowhere near Odin in terms of power. Odin respects him and treats him as his equal, but that's about it. Thor stalemated Zeus for months. The greek pantheon gets beat down horribly.
I seem to remember that the Avengers back in the 80s invaded Mt. Olympus, and the 2nd Cap Marvel didnt do a half bad job aginst Zeus himself; hell, she even *hurt* him.
the rest of the pantheon R a non-factor here, and if we're talking all 7200 GLs.......this fight ends quickly.
The biggest power ratio establisher for Zeus was the the months long stalemate on Olympus between Thor and Zeus, during which Zeus declared that Thor was more powerful than all the other Olympians put together. So Zeus is either equal to or a little more powerful then Thor. Odin is thousands of times more powerful then Thor. Odin is so far beyond Zeus you can't even compare the two.
