40th: Grant: Cyllage City
Featured in: X and Y
What makes Grant unique and also stupid is that he doesn’t have a lead pokemon. Both of his pokemon are the same level and they are both closely related. For Pokemon to take a chance for once and place rock in a different time in the game besides the first gym it really sucks that they just gave him both the fossil pokemon unevolved and called it a day.
and then you fight him and it's like oh
