The Snake & The Siren
Bill Cipher. A dream demon with unstoppable and very powerful. After he was 'defeated' and turned to stone his rage was powerful enough to break it. The only thing was that he was sucked into a vortex. He landed in an unknown dimension that he has never been to before. He was turned into this snake hybrid and couldn't use his powers. He slightly freaked out until someone, or something told him 'you'll get your powers back after you've found what you've been missing your whole life'.
