Summary:

Starting with the first episode of 2012 and the 63rd episode overall, January 5th's A Subterranean Gym Match! VS Yacon!!, Pocket Monsters Best Wishes featured the this ending, the third unique ending song used in the series but the 5th overall ending when accounting for different verse variants of the first two endings.

Titled "A Seven-colored Arch" (Nana-iro arch 七色アーチ), the ending features a chorus of multiple generations of Pokémon singers; Toshiko Ezaki, the singer of Advanced Generation's Soko ni sora ga aru kara and Smile, Fumie Akiyoshi, the singer of Diamond and Pearl's Together, Kono yubi tomare and Saikō everyday, and Aki Okui, the singer of Best Wishes' Kokoro no fanfare. The ending replaced Can You Say the Pokémon? BW (Version 2) ポケモン言えるかな？ＢＷ (バージョン2) which had been the ending song since BW54.

The song features Dent as its conductor, and is perfectly suited for school graduations and entrance ceremonies, cheering on good friends and compatriots as they head towards their future. Satoshi and Iris are also featured heavily with their Pokémon, so sing along, everyone!

The ending also revealed new evolutions of some of the main characters Pokémon as well as a new addition including: Dent's Iwapalace, Satoshi's Waruvile, Satoshi's Hahakomori and Satoshi 's Chaoboo . Satoshi's Gantle was actually revealed earlier in BW63 which was the episode that this ending first aired in so it wasn't considered a spoiler.

Animation painting error: Satoshi's Gantle's rock ridge is painted red instead of blue. It was later fixed in BW66.
