Mephiles felt it. The attack unleashed by the awakened Sonic the Hedgehog, enhanced by the Chaos Emeralds and the Elements of Harmony. However, he would not allow himself to be destroyed in the Solaris form. Opening a tear into the very planes of existence within the tear in reality and escaping into it, Solaris was able to escape destruction and left a dead shell behind to fool their enemies. After the mad god went through the new tear, Solaris closed it so that Sonic and his allies would never be able to pursue them to finish the job. Granted, time distortion had to be used but it was executed so flawlessly that they didn't see it happen at all.
Solaris fragmented and Iblis became a separate entity from Mephiles, having recovered his physical form by absorbing energy from the darkness surrounding him.
"It seems that I am back. Now just to gather more power and then unleash death and destruction upon Equestria when the time is right!" the Dark Mind cackled evilly as he absorbed dark energy.
The plane of existence that Mephiles had escaped to was a plane that the ponies of Equestria would never be able to pacify. It was known as the Black Existence Void because the very plane itself was similar to a black hole in appearance and that only evil beings are capable of surviving the harsh environment of the Void. The ponies, being creatures of light, would die instantly if they tried to enter. Even Celestia would barely last a second in this unforgiving realm. Iblis no longer identified itself as a female. Its new masculine humanoid form was enough to prove this.
"We shall remain in this dark plane of existence, Iblis. If we are lucky, then the fools will think that he had actually died. I'll wait for nature to take its course with Sonic and his friends, then I will return and plunge Mobius into a perpetual Dark Age!"
