Melascula comments that Meliodas is in his Assault Mode, the feared leader of the Ten Commandments back then, and that is the end for them and her.

Merlin creates a Perfect Cube around Escanor and Meliodas so they can fight with their full power. Escanor joyfully states is the perfect time to prove he is the strongest but Meliodas, reverted to his old self, is willing to prove him wrong and they start fighting.
