Ep 15. Duel in the Desert

Dan and his friends head off to the middle of nowhere to visit Julie who lives near the Bukugan Valley. Rumor has it that this is the place where the Infinity Core is. Our heroes want to find it and figure out what they can do to stop the Core from spreading its evil power around the world. In essence, shut down Hal-G and Masquerade and ultimately Naga. After a short trek, they find it, but before they can continue their investigation, they meet up with Julie's friends Billy and Komba. These two challenge the Brawlers to a battle. The twist is, both Billy and Komba are aligned with Masquerade and they want to send the Brawlers' Bakugan to the Doom Dimenison. The battle heats up as Shun and Julie enter the battle.
