Keeping his identity from becoming lost with the help of the [Chain], Sunny channeled the essence of Serpent and assumed its form.
Actually, the form of Soul Serpent was the opposite of what those words usually meant — it was a state of utter formlessness inherent to the shadows, and therefore the reason why they could take any shape.
Sunny found it surprisingly easy to assume that shapeless form. After all, there were a lot of parallels between him and Serpent, as well as between the powers they wielded... and for a good reason.
Serpent was unique among Sunny's Shadows. Sunny had earned the rest of them in a variety of ways, most of them involving slaying the original... the Stone Saint, the Ravenous Fiend, Nightmare, Slayer, the Mordant Mimic. As such, his Shadows came from creatures he had met and killed.
