Pikachu and Ash go way back. They’ve been travelling with each other for over 500 episodes. They’ve been with each other from Kanto to Unova and they have grown along the way. Pikachu has probably passed level 99 years ago.

Ash Ketchum has caught many different pokemon and will constantly improve. While Pikachu and Ash will never become Pokemon Masters they try. Pikachu takes a loss in this match. He just can’t match up against the power of all of Ash’s pokemon. He has far too many. Ash wins.
