Ummm, yeah....
Nor can you (or anyone) prove that Link's shield could NOT stop an attack by Kratos. This is a pointless arguement because the very universes are incompatible. However, since people insist upon arguement - here's something even more useless....
My level 75 Stormcaller (or lvl 72 Diviner) from Titan Quest would own both Link and Kratos. However, my level 93 FoH/Hammerdin from Diablo would beat any character from Titan Quest. Therefore "Glaamdring the FoH Hammerer" rules all.
Go Glaamdring!
Pointless!!!!
