29. Pain by @NosaneTryhard (Nosane Tryhard)

From his previous description, the body on Bizarro Sephiroth's head represents the part of him that's still human, his very part that regrets for what he has become ad it is trapped between his body and Jenova's control, unable to break free and take control of himself.

Despite of that, even in his corrupted form he still has a part of the pure hearted person he once was, and it will always be with him.
