The only way to beat the giant Beta is via direct attack to the brain, forcing Ogre into a very perilous situation. Auctioneer risks his life to locate the brain, and Ogre uses Number 11 to take it out and defeat Beta.

He reunites with the Squad and celebrates, but his joy would be short-lived.
Victory is mine.
النصر لي
Der Sieg ist mein.
Porque ganaré yo.
Porque voy a ganar yo.
C’est moi qui vais gagner.
A vincere sarò io!
Eu serei o vencedor.
Победа за мной.
