Well actually since I mentioned it, why not. For the record, I know some of these have people cast for them already, this is just my list, who I would have picked. Also I didn't do all the characters each person had nor characters from all people. I just did some that came to mind.

[b]Raptor's Characters:[/b]
[b]Nightmare-[/b] Played by Bill Nighy

[b]Aurelia- [/b]Played by Jaime Murray (She's been known to play roles involving altered skin and hair color as well as non-standard outlooks and done them extremely well so would be my first choice there.)

[b]Neutral Nexus' Characters:[/b]
[b]The Cowl-[/b] Played by Eric Roberts (This guy plays a classy but corrupt blackmail style criminal villain like he was born for the role.)

[b]Umbraxis-[/b] Played by, sorry have no idea here.

[b]Nightmareshape's Characters:[/b]
[b]Forsaken- [/b] Played by Benedict Cumberbatch (Came to mind almost immediately. Was brought to mind by his job in the Star Trek film.)

Athinar's Characters:
[b]Equilibrium-[/b] Played by DJ Qualls (The perfect mixture of awkwardness and determination in most of his roles.)

Kalistar's Characters:
Radiance- Played by Kristen Bell (This may or may not be due to her role as El from heroes but electrical powers seem to go very well with her.)
