Mewtwo was in deep meditation. It was about to complete his training.
But suddenly, "PI! :D" a Pichu interrupted happily.
Mewtwo then thought to its self, "Ugh what's this runt doing here?"
Pichu then shock Mewtwo out of excitement.
Mewtwo teleported to another part of the cave, and Pichu started feeling sad.
Pichu then decided to run around to look for Mewtwo, and when he found it, he shocked it again.
This repeated until Pichu tried to tell Mewtwo that he wanted to train too. Luckily, Mewtwo received the message, and started to charge its energy ball. Pichu head butted Mewtwo, and then it rose Pichu, and threw him at the wall. Pichu wasn't done yet. He used thunder, and then Mewtwo used its energy ball. They both got knocked away, walked up to each other, and shook hands.
They decided to be training partners until Pikachu and Jigglypuff got back from Smash Bros.
