LMFAO we have Hypersonic Harpies travelling from Rhodes to Etna in under 5 minutes, multiple instances of Kratos shooting Zeus's lightning bolts and parrying Zeus's bolts in GOW2, nevermind the fact that a literal speed-of-light dash attack exists in the Ascension multiplayer which is essentially a nerfed version of Zeus's own dash (Kratos being superior to said dash). WoG being "dubious" is just them huffing on the copium, heck we wouldn't even neeed to use WoG if idiots like these actually took the source material at face value: WoG is literally there to clarify shit that already exists within the actual source material, like the games, comic books, the interviews, the guidebooks and artbooks. Oh, let's not forget the Primordial War, where beings literally have a universe stored in their chin.
Like, just the novels alone would tell you just how crazy powerful the Olympians and Titans are while they massively hold back. Poseidon shakes the world just by raising his fist, Ares shakes the world and the heavens above with his roar, and even Zeus shakes the foundations of the Greek World with his voice as well. Hell, the Great War literally forged the landscape of the Mortal World all the way from Tartarus. Even Atlas outright states that Kratos has the power to quake the entire world on a whim.
And it absolutely isn't out of character for Kratos to start with hax right off the gate if Ascension is anything to go by.
