Little Battlers eXperience (2011) : 1x3

Ban is challenged by Gouda to an LBX battle. In order to make it "fair", Gouda lets him use the Achilles armor and confidently tells Ami and Kazu that they can battle against him as well as a handicap. Seeing that they have no other choice, Ban accepts his challenge in order to protect Achilles. It is also revealed that Gouda is doing this under someone else's bequest. While the trio are preparing for the battle against Gouda, they decide to use a hit-and-run strategy against Hakai-O since it specializes in close quarters combat. The plan seems to work for a little while, until Gouda shows them his LBX's true abilities by first activiting the Gao Cannon and swiftly destroying Kazu's Warrior. Without their teammate, Ban and Ami are in a pinch. The first blast from Hakai-O's cannon was a demoralizing tactic, but they don't give up. In fact, Kazu finds out Hakai-O's Achilles Heel.
