My (cliche) guess is that Mezool will power up Gamel and sic him on the others and Uva or Cazali does something smart and makes Gamel kill Mezool. Gamel goes berserk and kills Uva or Cazali, and Cazali or Uva (whoever that isn't dead) kills Gamel. Then in that moment of spent triumph, Ankh jumps him and kills him.
Maki then arrives and makes a speech about the end of the world, and him and Ankh fight, mirroring the PutoTyra vs. LAnkh fight. Ankh wins with the help of OOO and then Cakeboss will reveal himself.
