Summary:

Unbeatable is the eighth dub opening which debuted in the Pokémon: Advanced Battle episode "Clamperl of Wisdom!". The opening includes clips from the Japanese openings Pokémon Symphonic Medley and Battle Frontier (バトルフロンティア).

The first scene shows Ash and his current lineup of Pokémon battling Regirock, Registeel and Regice in a stadium as all of Ash's Pokémon charge Regi evolutions. Pikachu is the last Pokémon to be shown and he uses his Thunderbolt in a forest causing a huge explosion with smoke flying everywhere.

The next scene features Ash and Pikachu running down a hill until they get near the bottom and then jump into the air. It is followed by a scene of Brock holding a bouquet of flowers as he jumps around a bunch of silhouettes of girls until his flowers are eaten by May's Munchlax.

Mew and Jirachi fly through a bunch of ruins in the sea as Groundon and Kyorge battle and Entei, Suicune and Raikou jump from ruin to ruin as they fall apart behind them. Pikachu uses Iron Tail and the Advanced Battle appears.

A valley full of hundreds of Pokémon is shown as Celebii fly's by and it transitions to the ocean. It transitions again to more Pokémon flying in the air and running on the hills. It then transitions to Regirock, Registeel and Regice in a stadium battling Ash's Pokémon as the attacks fly past Ash and explode behind him.

A mysterious Pokémon is seen in an alley way that looks like Mewtwo covered in a cloak as it jumps into the air and then the Advanced Battle logo appears on screen again in sync with the lyrics. Delia, Professor Oak, Professor Birch, Tracey and Misty have quick appearances together as the video scrolls up to show them.

Deoxys soar by as Ash and Pikachu watches it fly high into the sky as Articuno, Moltres, and Zapdos joins it as they approach space. Ho-Oh also fly's by and the Battle Frontier Brains silhouettes are seen posing together.

It quickly changes to Team Rocket digging a tunnel underground until Aron, Lairon, and Aggron start chasing them. Ash's Pokémon are quickly shown as Ash and Pikachu jump into the air and the Pokémon Advanced Battle logo appears.
