Don't forget about Terra (Branford, that is). Perhaps we should call her Terranea.

Here are the new characters I'd like to see in the next KH:
III: Luneth, Arc, Refia, Ingus, Cloud of Darkness
IV: Cecil, Rosa, Kain, Zemus
VI: Terranea, Locke, Celes, Sabin, Kefka
VII: Vincent, Zack (returning from BBS), Lucrecia, Red XIII
VIII: Rinoa, Laguna, Quistis, Irvine, Ultimecia
IX: Zidane, Garnet, Kuja
X: Lulu, Seymour
