3

Gouda returns the Achilles frame to Ban and reveals he was told to take it to keep it out of the hands of dangerous organizations on unsmart kids. He then challenges Ban, Kazu, and Ami to a 3-on-1 battle against his Hakai-O, AKA the Destruction God of Hell. Kunoichi is customized for speed while Warrior and Achilles are customized for short distance shooting. The three also come up with a strategy to take down Hakai-O using hit-and-run tactics. The plan backfires on them when Hakai-O uses his Gaou Cannon to create a smokescreen. Hakai-O then moves in on Warrior and crushes him. The second time Hakai-O uses his Gaou cannon Kazu realizes that Hakai-O temporarily goes offline because of the amount of power that it uses. After the third attack he tells Ban and Ami the news, and on the fourth attack Ban is able to grab Warrior's gun and take out the Gaou Cannon before moving in and knocking him out of commission. Gouda keeps his word and lets them keep the Achilles frame. At the Innovators headquarters Yagami is on the phone and tells them not to worry about Achilles being completed. He has come up with a plan to destroy Achilles in a LBX battle, and he creates a new dangerous LBX to do the dirty work. (Source: Wikipedia)
