Link destroys the worm, and eats him for good measure.

Calling what happened next a fight would be an insult to combat. The demon thought he could outflank her with his teleportation, but what he seemed to fail to notice was that with Faron's magical senses, Link was able to pinpoint where he would appear next. The second he reappeared behind Link, all Link needed to do was reach back with one claw and snatch him out of the air, and with Faron's magical knowledge he immediately bound the creature's magic, trapping him in her clutches. Link pulled Ghirahim in front of her face, and found himself thinking of a beautifully fitting ending for such a diseased and rotten beast. He took the demon lord, barely an insect to him in this body, opened his mouth, and threw him inside, swallowing the fiend with a single gulp.

For a moment, something in Faron's memories flashed out, telling Link this was a bad idea, but it was ignored quickly. He was bound, of now harm no him or Zelda any more. As Link turned to fly to Skyloft, where he could use the mirror to return to his old body, he suddenly felt a surge of...something inside him, and let out a small belch involuntarily. Link frowned, as such unwholesome noises were not to be down by a sacred dragon, not at all. But then he felt his body surge with power, power like he had never felt before. His frown turned into a smile as pleasure and magic suffused his form, which began to twist and change. The scales on his body became paler, his limbs more slender, his face more human. Large breasts filled his kimono, and if Link had felt like somewhat godlike before, she felt like a complete goddess now. Her changes ending, she looked down in satisfaction, excitement rolling through her in waves. Why would she return to that weak and human body? With a body like this, she could easily protect Faron Woods. And Eldin Volcano. And Lanayru Desert. The Sky, as well. In fact, she could rule everything!
