It's the battle that everyone is looking forward to (except for Masquerade). The showdown between Dan and Delta Dragonoid vs Shun and Storm Skyress. As everyone gears up for the battle, they wonder if Dan will really be able to beat Shun, and what will happen if they can't. As Dan and Shun's battle is about to begin Joe and Wavern both join in to watch the battle and with everyone assembled the battle begins. Meanwhile, Christopher wonders where Alice disappeared to as her alter-ego, Masquerade, continues his battle against Exedra with things going well. Dan and Shun's battle rages on and things look bad when Drago goes down and doesn't get back up, but with encouragement from everyone including Shun and Skyress, Drago gets back up to finish the battle. Meanwhile, Masquerade pulls out a complete turn around against Exedra. The battle between Dan and Shun finally ends and the winner is Drago. Drago begins to evolve, changing from Delta Dragonoid to Ultimate Dragonoid while increasing his power level.

- The dub title is a reference to the Beatles song "Revolution", which contains the lyrics "You say you want a revolution". This pun was also used for the Pokémon episode "Ya See We Want an Evolution", which aired around the same time as this episode in Japan.
- In the dub version, when illusion Alice loses, she shouts "Exedra!". In the Japanese version, it's unable to hear what she says.
Some scenes were redrawn between the Japanese and overseas versions.
