Ash's Frogadier is the evolved form of Ash's Froakie. It evolved during a battle with Saizo's Barbaracle. As a result of evolving, it learned Aerial Ace. Bonnie was disappointed that she didn't get to see it evolve and wanted it to turn back into a Froakie so she could see it evolve.
Despite evolving, learning a new move and becoming stronger, it couldn't overcome the EXP that Ash's Frogadier had and was quickly knocked out with a blast from Water Pulse. Sawyer vowed to Juptile that they should become stronger. Sawyer's Grovyle became Ash's Frogadier rival after that battle as the two locked eyes in anticipation of their rematch battle.
