If It Were Different (Pokemon Fanfic)

This story is how I imagined what life in Kalos would have been like for Ash and his Pokemon including his friends. With instead of him losing the league he actually wins and proceeds down the path to becoming a Pokemon master with his team; Talonflame, Pikachu, Greninja, Hawlucha, and Noivern.
Though even after winning the league the dangers brought by a mind controlled Zygarde had to be freed from Team Flare and Lysander's control. During the time as both Zygarde and Squishy destroyed the remains of damage to Kalos, Greninja did have to leave Ash and his friends behind to help the legendary Pokemon on their mission it takes time but a couple of years later.
Greninja does return to a now full grown Ash and the other Pokemon all happy he's returned, Ash has become a full trained Pokemon master. Over the years, even now Bonnie is a trainer with Squishy traveling by her side, Clemont now a great inventor, and Serena reaching her dream as Kalos Queen.
Though since everything has gone well for these fine heroes, this will talk about the Pokemon's POV.
