He opened his eyes, which were covered in mako. They glowed an eerie green. He looked at his surroundings, seeing the damage around him. But stranger still, he realized that he hadn't caused it. However, his mood soon changed when he found that a slight tingling sensation was occurring on his right shoulder. He embraced it, and with a glow, a large wing appeared on his back. It was black, but resembled that of an angel's wing. He knew what this meant all too well.
And with great speed, flew using his wing to wards Cloud's location, shining like a beacon in Sephiroth's mind.
