Doesn't take long to kick in, mere seconds.
That and he has Reactive Evolution incoming.
Since all of then are fighting in absurd high speeds at the start of the fight, plus Raiden who starts by spamming stat amps, mere seconds would last a lot longer in his perspective, that would give him more time to **** up Kratos over , before he stat checks Raiden with rage boost.BTW Raiden has his own Accelerated Development that can kick in this fight, he was able to cut through Armstrong body before the nanomachines could cover up him in time to block his strikes, before that not even blade+ripper mode 10x speed amp was enough to blitz the nanomachines.
Still magic that Raiden wouldn't be able to fully analyze until after it's already been used.
Don't need to, doing the action of pulling out, is enough for the AI to mark Kratos hands or arm joints with a big ass red square indicating >>>PLEASE HIT ME<<<, also the fact that it's a device that even sci-fi tec cannot comprehend would just give in a massive red flag giving him even more reasons for him to not let Kratos activate that thing and cut his arms into pieces before he has any chance to so.
Kratos in Rage Mode also becomes auto-bloodlusted and can literally power through most of the hax that he's shown being Resistant against, and he even gets a greater power boost as a result.
But Kratos in GOW hasn't show to resist or tank anything that has the same ability as the HF blade, who would be completely alien to him because i'ts a futuristic tech that manip quantum bonds to cut through anything like butter.
Gorgon heads can do AoE flashesa and Raiden is a CQC fighter.... one single thought of activating the rage and Raiden can be murked.
Here is a small little problem,none of Kratos hacks are thought based or happen on a instant.
Ouroborus:need to pull out the amulet out of his pocket.
Medusa:same thing as well,plus he needs to charge up the blast for a few seconds before blasting the area with petrification
Zeus Lightning:either grinds his blades to summon the AOE or lift up his hand to get lightning bolts and throw at the guy.
Hands of Hades/Ghosts of Hades:grinds the chaos blades with a delay.
Poseidon's Rage:Jump and summon the eletricity.
Raiden would see all of those activations in slow motion and chop Kratos in those moments, he would see Zeus/poseidon lightning in slow motion as well, back the **** off and engage into CQC range again when i'ts done.He has 2 opportunities to do all that things that i mentioned, because
a 5x speed diff is enough to blitz already and Raiden has double of that.
