Episode 453 – Grating Spaces!

Episode Summary
On their way to the Battle Pyramid, Ash and friends arrive in Pewter City to find the gym redecorated! Brock’s siblings explain that three people convinced their parents to get the gym redecorated to make it look nicer and then they sent Flint and Lola on a vacation! When Brock looks at the inside of the gym it looks just as bad, and he finds out that his Onix has evolved into Steelix! Then, the re-modelers, who are actually Team Rocket in disguise, return with a new Charizard and Aggron given to them from Delibird (and actually meant for Butch and Cassidy) and challenge Brock and Ash to a battle to decide the fate of Pewter Gym!
