It had been six years since Ash had last faced Diantha, the Champion of Kalos. Now on the battlefield, where unofficial matches were being held for the people's enjoyment, Ash and Diantha faced each other again. Ash swore that this time, he would definitely beat Diantha. Diantha sent out her Gardevoir, while Ash threw out a pokeball revealing his faithful Greninja.

Up in the stands Paul, Sawyer, Gary Oak & Alain as well as Serena, Lillie, Mallow, May and Dawn were watching. The referee raised a flag. "LET THE MATCH BETWEEN ASH AND DIANTHA BEGIN!"

"Moonblast!" Gardevoir fired off a pink Sphere of energy that hit Greninja directly. However it was revealed that Greninja barely had a scratch on him. "WHAT?!" Diantha and the crowd were shocked. A super effective fairy type move for some reason had no effect on a dark type. "Gardevoir mega evolve" Diantha pressed her keystone and her Gardevoir became Mega Gardevoir. Ash grinned for he had been waiting for this.

"Alright Greninja LET'Z GO!" A massive vortex of water surrounded Greninja, and he grew a red crown and several black red spikes before the water veil split to form a large water shuriken on his back.

"ASH-GRENINJA!THERE IT IS FOLKS ASH-GRENINJA IS BACK!" the crowd went wild. Up in the stands Gary and Paul and all of the girls except Serena looked with wide eyes.

"Water Shuriken!" Greninja reached for the huge shuriken on his back and threw it at Gardevoir who fired off a Moonblast in response. The moves collided and cancelled each other out. "Shadow Ball!" Gardevoir fired a large ball or ghost type energy towards Greninja.

"USE NIGHT SLASH!" Greninja sheathed a meter long sword of purple energy and clove the ball in two in a single strike. A Moonblast followed soon after and Greninja, not dodging it, was hit directly again. However it still had no effect whatsoever. "Double Team and then Night Slash!" Dozens of clones of Greninja suddenly surrounded the battlefield, each of them holding a pair of very long Purple Swords before rushing towards Gardevoir at blinding speeds. Gardevoir barely put up a Reflect before all the clones smashed their blades against the psychic barrier, shattering it instantly and sending Gardevoir recoiling violently.

"Now AERIAL ACE!" Greninja suddenly appeared in front of Gardevoir, uppercutting her with a glowing fist before landing several more swift punches on her. (Imagine his fight with Wulfric's Mega Abomasnow except now Greninja is much faster stronger and precise). A final kick sent Gardevoir crashing into the wall behind. "Gardevoir are you okay?" Diantha asked worried. Gardevoir emerged covered in bruises and injuries, but nodded.

"End him with Dazzling Gleam!" Gardevoir's body shone with a bright pink light that shot towards Greninja. Ash merely smirked. "GRENINJA USE SAMURAI BLADES" "What's samurai blades?" Everyone wondered. Then Greninja unsheathed two absurdly very long katana swords of radiant blue aura. He then began to spin them rapidly (Imagine Zoro's Sanzen Sekai when he destroys Pica) until they're whirling like helicopter blades and cuts completely through the dazzling gleam and critically hits Gardevoir with a devastating cross slash. Gardevoir has taken immense damage and is on her last legs, but she still tries to stand.

"Gardevoir let's give it one last shot! GIGA IMPACT!" Gardevoir charges at full speed surrounded by a white-pink aura. "LET'S END THIS! HYDRO CANNON!" Greninja cups his webbed hands together before unleashing a colossal, explosive burst of water that would have made Primal Kyogre cry out in envy. The Hydro Cannon easily overpowers Gardevoir and slams her all the way into the wall leaving a massive crater. An unconscious Gardevoir fell to the floor, swirls in her eyes.

"Gardevoir in unable to battle. Greninja wins! Therefore ASH IS THE WINNER!" The crowd went wild especially Serena, Lillie and the lot of girls seeing that Ash had stomped the Kalos Champion. Gary, Alain and Paul were all considering asking Ash for a battle later.
