As the battle begins, Shadow brings out his gun and shoots down a bunch of Heartless while Cream kicked a Shadow Heartless in the head and the Powerpuff Girls use their powers on other Heartless.
Sephiroth: (as he brings out his Masamune) Time to bring those beasts down!
With that, using his very long sword, he slashed down a lot of Heartless that are close to him.
Shadow: When we find you, Scourge, it'll be payback time for what you did to me and ream!
