It wasn't too long before they finally caught up to Necrozma. The clouds in the sky by then had cleared up, covering the land with the sun's light.
Dialga didn't seem to waste any time once Necrozma came into view. The moment Necrozma started to slow down, Dialga immediately shot Flash Cannon at him and he let out a cry as he was blasted to the ground. Giratina stepped into view and held out the prism. It slowly started to glow, along with Necrozma, who seemed to start radiating with white smoke.
"No- what are you- Let go of me!" Necrozma spat out, as he seemed to struggle as if something was preventing him from moving forward. He looked up to Giratina, almost glaring at him even though he didn't have any eyes. "Who- who are you?!"
"My name is Giratina. Lord of the Distortion World." He said to him mercilessly. "Don't expect me to remember you in the future."
Necrozma's body started to glow, as he became engulfed by the white smoke that started to absorb itself into the prism. Necrozma desperately tried to run. Not that it mattered though, the smoke pulling him back seemed to be too strong for Necrozma to fight. But it still took all of Giratina's strength to keep himself from losing his grip on the prism.
"Giratina- I won't- I won't forget you!" Necrozma spat out. "You'll- You'll pay for this- no matter what! Don't dare to think that you'll-"
He was cut off by a cry of despair as his body seemed to melt into black and purple smoke, and the white smoke that was holding him immediately sucked itself back into the prism.
Giratina collapsed out of exhaustion, Dialga quickly ran over to help him up. He looked back at the prism, which was glowing brighter than it had before, with a small aura of black and purple smoke radiating from it.
