As much as I hate Sinnoh, from the voice acting to the region to its blandness, I have to say Sinnoh.
"If Pikachu becomes a Raichu, I might be able to win that badge. On the other hand, to make it evolve just to fight...I would be just like Surge...Pikachu, what do you want to do? I really wanna beat that Surge, but I also don't want to force you to evolve if you'd be happier staying the way you are now." -- OS Ash, ESS
