Iblis

Iblis is the fiery power and destructive nature of the god Solaris.

Sealed and Released
Iblis was a spirit born during an experiment when Solaris, the god of time, light, and fire, was split into two halves- Mephiles, who consisted of power and intelligence, and Iblis, who consisted of Solaris's fiery power and destructive nature. The Duke of Soleanna, who had been experimenting with Solaris, along with his researchers, had no other option but to use the power of a Chaos Emerald to seal the energy within his daughter, Princess Elise, dying in the process himself. It would remain that way until Elise gave into despair, trapping her in a life of feigned optimism. Mephiles, who was trapped within a device called the Sceptor of Darkness by Shadow the Hedgehog, was released years later and created a plan that spanned over two hundred years, which resulted in the release of Iblis among other things. With the power of the Chaos Emeralds, Mephiles rejoined Iblis and Solaris was reborn. Iblis's existence was ultimately erased when Sonic and Elise traveled back in time to the days before Solaris was experimented upon and snuffed the tiny white flame. (CSE)
