I think that this fight would last a verry long time. It will all go down to physical power and Zeus would win as far as physical power...BUT, Zeus is a never ending power source for Cole and Cole can draw from the power of Zeus and keep healing, heck maybie a punch from Zeus would feal good to Cole, what do you guys think?
As for Zeus being immortal, I think the last few games have shown that the "gods" are not immortal, just powerful. Cole could win. But I agree, I think he would loose.
Its like trying to kill (excuse me on this reference but it is the only one I can think of) pikachu with electricity. It kind of won't work. (btw, I havn't played that game since I was in middle school.)
I disagree bud, have you noticed that most if not all of the gods have been killed by relatives/and or other Gods? They are immortal,but not on the level of characters like Dr. Manhattan.
As far as the Battle goes this would end quickly,lets think for a second,Kratos needed a great deal of help to defeat Ares and even more to even Tango with the King of Olympus,I am sorry but Zeus would probably pop his head with Telekenesis.
