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 know Number 11 by itself 
isn't enough to take me out.
أعرف أنّ رقم 11 لا تكفي بمفردها لهزيمتي
Was ich dir sagen kann, ist, dass Number 11
nicht reichen wird, um mich zu besiegen.
Sé que no puedes vencerme
solo con el número 11.
Sé que no puedes vencerme
solo con el número 11.
Je suis certain d’une chose.
Io lo so.
Eu sei que somente o Número 11
não é capaz de me derrotar.
Самого по себе номера 11 не хватит,
чтобы справиться со мной.
