I had this idea some days ago

of Iblis return to Sonic story's

this how i came up with it.

Sonic 06: Silver dark future.
Blaze use the chaos emeralds to send herself with iblis to an alt dimension and time.

when time was reset, Blaze and iblis was hit by a shockwave of time and space, causing their fusion to missfire and they become apart.
Blaze gain more fire power and Iblis lost most of its fire power.

Blaze story then come into the sol dimension.

as Iblis become Sonic Rivals 2 end boss.

a Dark force goes to that world and give Iblis the monster a focus on the mind, it then focus and take on this from, that like Blaze as they sheared part of their time.

the evil one bring her back to the world as she now begin chaos across the land burning all in her new from.

and with high chaos energy's she can return to her full IBLIS monster-us from.

What you all think?
