Recently I've been on the Pokemon X & Y official website and I saw a picture with a level 5 Chespin in it and it knows Vine whip. Do You think that the starter Pokemon have at least 1 basic move of there type as soon as you get them?
I found out that Chespin has vine whip, Fennekin has ember & Froakie has bubble.
We dont know for sure since it hasnt officially been released that they would have them as soon as they started out. So they might or then again they could have just been hatched from eggs and had got the move from one of their parents(though this is unlikely). Either way there is no way to tell until more information about the starters is released.
