Upon finally fusing back with both Reshiram and Zekrom, Kyurem unfurls its wings and makes itself known.

Reshiram and Zekrom have returned to me. I am whole again at last. My eternal power hath come back in full force. The boundary between truth and ideals is shattered, and I, Kyurem, will make a true and ideal world for now and forever! For I am Kyurem, the original and the perfect dragon!
