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.
It'll be fun to see everyone in Tokyo cower in fear 
after I turn 'em all into bombs.
ستكون رؤية ارتعاب الجميع في طوكيو
!بعدما أحوّلهم لقنابل ممتعة جدّاً
Kann’s kaum erwarten, den Schrecken auf
den Gesichtern der Bewohner Tokyos zu sehen,
Ya quiero ver los rostros de pavor
de la gente de Tokio cuando lo haga.
Tengo ganas de ver las caras de terror
de la gente de Tokio cuando lo haga.
Je l’utiliserai
sur tous les Tokyoïtes
La applicherò a tutti gli abitanti di Tōkyō
 per vedere i loro visi pervasi dal terrore.
Quero ver todos em Tóquio
encolhidos de medo
Вот будет весело, когда я превращу
всех жителей Токио в бомбы!
