>>47396246>The whole point of this particular rivalry is a "slow and steady wins the race" type of lesson, since at most places he's ahead of you and looking for the next challenge without a second thought, and Chimchar is perfect for this type of trainerSince when? Barry has an impatient personality, but the game never indicates that he's impatient in how he raises his Pokémon. I think that describes Blue more than it does Barry.
Also since when does a Pokémon's personality have to match its trainer's? You could argue that Chimchar fits Barry more because he's always in a rush, but you could also argue that Turtwig suits him because it's a good foil for him and it would force him to slow down sometimes.
