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.
I'm here to take Number 11, 
just as I said I would.
أتيتُ لأخذ رقم 11 كما قلت أنّي سأفعل
Und ich werd dir, wie angekündigt,
Number 11 abnehmen.
Comme promis,
je suis venu récupérer Numéro 11.
Come promesso,
 sono venuto a prendermi il Number Eleven!
Como prometi, estou aqui
para pegar o Número 11!
Я же говорил,
что я здесь ради номера 11!
