Palpitoad is on the VA list! It is him and Oshawott, Scraggy, Pignite and Pikachu. They are the only Ash pokemons in the entire VA list!
Dude you do realize that the others aren't listed because they share VAs with the other charactes right?
That and how do you know its a big role.
The biggest thing Palpitoad will do in this episode is appear outside of battle. :(
I like to see Ash's father appear and take care of Team Rocket .
Ash seem to have some resentment toward his father for not spending enough time with him in Childhood But ash's father doesn't seem to feel any guilt for this .
Instate , He insult Ash for losing the Unova League in a Pathetic way and even has a battle with Ash where he win.
Then he tell Ash that Ash always let his guard down sub-consciously against anyone who has a disadvantage over him and that why pathetic trainer like Kotetsu & Trip can beat him easily .
He left telling Ash that he should train his mind first before going on another journey so Ash train for year before then set out to Kalo region .
