So who do you think is the other 6 darknesses?

[Cosmic+Amarna]

What if Xehanort used Xigbar's and Saix's whole forms and Nobodies? I don't see why not.

Because Sora destroyed both of them (Isa's and Braig's nobody) during KHII.

Or like if Xemnas and co. seeded Saix and because of this Isa would be a Nort as well once restored by default, and since essentially all Xehanorts have the capability to time travel, then both Xigbar and Braig could both 'exist', as well as Saix and Isa. However I do not think this will be though, I think this because Braig was Norted in BBS and Lea calls him Isa in the end of DDD.

Braig's Nobody could still be transformed, and I fail to see the importance in what Lea calls his old friend. Saix says "Lea" in Days.

 

[Vanitas666]

13 darknesses
- YMX
- MX
- XH (with rikus body?)
- Xemnas
- Braig
- Isa
- Xigbar
- Saix
- Vanitas
- Terranort
- MX nobody
- Rikus something from monstro

that's what I think. I wrote Braig and Xigbar (same with Isa) because they have been recreated but YMX might be able to travel and get them, seeing how they had a part of Xehanort in them.
