1) I don't want to bring half-life into this because that is too many characters already. Gordon freeman will be in it but that is it. He is a metal bender and one of Chell's teachers/friends.
2) Possible something powerful that spirits use and Gray and others want to find and use it. immortality? Strength? Power to take/give bending? Many possibilities.
3) Ehh, perhaps a man trying to start up a business but piss off the spirits while doing so.
5) Yeah they could but I rather not. Too many characters.
6) Perhaps. Sounds like it.
7) LoL XD
8) He is a spirit. Along with the others that Merasmus has conjure up. But they are not control by Merasmus.
9) Maybe Demo's missing eye, Pyro's spirit sense/vision going crazy, and Scout's spirit senses?
10) Yeah. They could be Grey's troops in taking over some areas and looking for the gang.
12) I like that idea. :]
13) Rich non-benders who want an useless island that is inhabited by spirits and Saxton stop the brothers from doing damage to it.
14) Something like that but with Engie there, I would think more metal bending weapons that can prevent benders from bending.
15) Some ideas so far madjesters1.deviantart.com/art…
16) Maybe to protect each others identity? Or just random nicknames? I never thought about that.
