You know, I'd actually like to see Red XIII in KH3. Before everybody starts saying that there's already been too many FF7 characters in the KH series, I'll explain why I'd like too see him in it more than Zack.
Red XIII was a great character in FF7, but he didn't really get much dialouge in Advent Children. In all reality, he played a small role in FF7 as well. In Dirge of Cerberus, he was damn near non-existent until the very end where you see him with Shelke. I'd like to see him in KH3, and have him play as big a role as Squall (Leon) did in the past KH games. It would be great to hear his voice or see his fighting skills in the game.
I just hope he doesn't appear with Cait Sith. I can't stand Cait Sith.
same here, i truthfully couldn't stand cait sith in FFVII, i saw that moogle doll and was like WTF is that? but i see your point on Red XIII but you know you just stated why square might not put him into the KH series you know?
