>>57947343This also brings me to the weakness that Kalos Ash has that Sinnoh Ash did not have. Kalos Ash immediately began to tunnel vision to Greninja once he realized he had a special form. He gave him a lot more focus and training than every other member of his team and this is what ended up biting him in the ass when he fought Alain in the end. If you rewatch Ash vs Alain, you quickly realize how badly trained his other Pokémon are besides Pikachu and Greninja. Ash getting Latias at this point is basically being shown as the equivalent to him being handed a perfected Ash-Greninja and this is before she gets a Mega Stone. The Paul he faces here is also probably above everyone Kalos Ash fights in the normal series besides Alain himself and he beat him. This sort of gives the impression that the only way he should struggle is if he intentionally refrains from using Latias, which isn't in character for someone like Kalos Ash or until we meet Alain.
So rather than being back to form as Sinnoh Ash...he's more like an emulation of Tobias, but instead of Darkrai and Latios, he uses Pikachu and Latias.
