I'm Unbeatable is the opening theme to the eighth season of the English-language Pokémon dub, Pokémon: Advanced Battle. It has been used since AG093.

The opening animation featured footage from the eighth and ninth Japanese openings, Pokémon Symphonic Medley and Battle Frontier. The inclusion of animation from Battle Frontier revealed three new Pokémon, Mime Jr., Weavile, neither of whom had official English names yet at the time, and Lucario, to North American, United Kingdom, and Australian audiences. However, all three were later removed.
