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.
Wait, no... Was it Number 16?!
!أيمكن، أيمكن... كان رقم 16؟
Nein … Sag bloß nicht …
Non… Impossible !
Non è possibile... Non è possibile...
Espera... não pode ser!
É a habilidade do Número 16?!
Неужели... Неужели это был номер 16?!
