I have this form for Immortal, and I might possibly make a book for it. In this form she truly lives up to her name and can shatter reality as we know it, giving her an upper hand. I plan the use this form at the end of a role play in the final battle.

When she's using her fragmentation, the most powerful attack, things go insane.  No gravity, portals everywhere, the reality is breaking into endless void! In this process she can actually create a new world using bits of all the worlds, it's insanely powerful, this is why you may never see her in this form.
