BW118: The Fires of a Red-Hot Reunion!

Synopsis
Heading towards the White Ruins, Ash and co. come across a special Kanto Fair, a fair celebrating the region of Kanto and the various Pokémon that dwell there. Ash is excited to see all these attractions that remind him of home and ends up seeing a cheerful Charmander right on stage. Reminding him of his old friend after telling his stories to them, Ash calls Professor Oak and requests that he sends over Charizard (since he came back from Charific Valley) while he sends Unfezant to his lab. However, once there, Charizard soon meets Iris' Dragonite and a fierce rivalry between them begins with a battle. Will the battle last? Who will win?

 * This would be the third time in the entire series for Ash's Charizard to battle a Dragonite since OI031: Enter The Dragonite and JE137: Great Bowls of Fire!, but the thing is: Iris' Dragonite looked different than the others due to the fact that it wants to challenge any Pokémon that it happens to meet and much thougher ones than itself to get as strong as possible as Jervius describes it in BW091: Iris and the Rogue Dragonite!.
 * In this episode, Ash decides to bring Charizard back to his team the fourth time in the entire series since he showed him how strong he becomes and join his journey in Unova.
 * Who's that Pokémon?: Charmander.
 * Though Liza did not have a speaking role, Lisa Ortiz provided the voice of the unknown female Charmander trainer.

 * Charmander's voice sounds less acute.
 * Primeape has a less noisy and loud voice.
 * Charmeleon's voice is no longer raspy, sounds like the voice of Aggron.
 * Aerodactyl leaves the pterodactyl screech, a sharp but distinct voice.
 * Poliwrath voice changes similar to a Vigoroth´s voice.
 * Blastoise's voice sounds much more low pitched.
