This is the Ascension strength feat I was talking about. Alecto pulls down an island sized building under the sea and causes an earthquake across the island chain/archipelago that they are in.
Kratos overpowers her in the last boss fight.
As for speed, I have a screenshot from the GoW1 website from 2005, where Kratos' short burst speed was compared with a thunderbolt from Zeus. (Which is fast enough to travel thousands of miles down from the top of Olympus to a desert in Egypt in what was described as 'an instant', so like a second at most.)
There's a lot more than just that, but I'm helping someone compile everything for a reddit respect thread, so that's where you'll see everything. Soon-ish.
