Charles North, who preferred to be called Chuck, had just arrived in Pallet Town after taking a Plane from Lumiose City to Cinnibar Island, and then taking a boat from there to Pallet Town. He made his way to the Pokémon Lab, where he saw another boy around his age and Professor Oak. When asked what starter he would like, he requested a Squirtle, whom he named Zeni, since the shell on it's back looked like the old coins known as Zeni.
