Pokémon: Collision Version

Just over 5 years ago, the world was sent into total ruin. When the dimensions of time and space collided, the legendary guardians went to battle. This battle was so colossal, our entire dimension was sent into ruin. Our world became desolate, cities being destroyed, entire countries being wiped out. However, there were those who resisted. Those who knew who to how to survive, how to get supplies, how to rescue survivors. A man named Kreet and his fellow survivors started the Klaw Federation, a team that took in the few that they could find, and worked together to stay safe until the battle was over. However, the disaster left few alive. Those who they found had turned bitter due to the catastrophe, and only three adolescents were recovered. Their names were Sam, Phillip and Harvey. This is where begins the adventure of young Sam.

Kleet: Professor Wicket, it is time. Those three must have their own Pokémon."
Wicket: Leader, are you sure they're ready?
Kleet: We have no choice professor. Your latest research has changed everything. We need everybody we can get.
Wicket: Okay sir, if you're sure...

      You and your friends Phillip and Harvey are in the Headquarters Meeting Room.
Harvey: I can't believe the professor is about to give us our own Pokémon! This is so awesome!
Phillip: Me neither! I've waited so long for this to happen!
       Professor Wicket walks in.
Wicket: I'm sure you three are fully acquainted with our current scenario, yes? Good. It's time that you all choose your Pokémon!
        Sam, you pick first.
You open the briefcase to find three Poké Balls. You open them up one by one. A Pansear, a Panpour, and a Pansage are sent out in front of you.
Which do you pick?
