ASODFIJSDOFJSDFOIJ! Sorry, happy button smash! THERE IS A VEXEN REPLICA!
Haha, sorry again, but I seriously wrote (am writing) an entire story (series, really) that focuses entirely on Replicas, so seeing one of them around is really exciting.
By the way, I love how you portrayed Even in this, too (really, I love your portrayals of everyone). He's... protective. Protective of Ienzo, and in then in the previous chapter where he kept Alexander out of harms way- I don't know, I just... I really like him that way.
*finishes reading*
darn, hoping I would have reason to not read the sequel :P
Just kidding, really. I want to see Terra brought back. So...
Wonderful story, I absolutely LOVED it. LOVED it! You did an amazing job. Seriously. Time to read the sequel.

OMG I LOVE THE BEGINNING OF THIS CHAPTER!
I love that interaction between Terra and Aqua - and I love Aqua - but I am very frustrated that Xavier left so quickly. He should've taken Aqua with him so that she could stop Xehanort or something... *grumble grumble*
*after reading for a while*
DEMYX!? I mean - EMYD!?
oh, and Lea (I actually had a feeling he'd show up)
and- I'm just going to stop comment on who shows up and keep reading
*reads a bit more*
Ack! He killed Braig!
Oh, he possessed Braig.
Eh, same thing, I guess.
*keeps reading*
ERAQUS!
whoo, I am really loving this story. Time to go read the last chapter!

Haha! I love you Braig! That scene between him and Xehanort was brilliant! It made me laugh; especially when Braig just left Xehanort there. Such a fitting end for Xehanort - since he becomes Xavier after this - weak and calling out to man that refuses to save him.
Yup.
Also, I love how you write Ienzo! I simply love him!
His comment, in this chapter, about how they all simply followed Xehanort instead of refusing him was very smart and true.
And I'm also very happy to find that Even is protective of Ienzo. I'm not sure why, but I love it.

Okay, so, I started reading this story out of shear curiosity. I really just was reading it to see where you took it, and wasn't entirely interested at first.
However, if you didn't have me when Alexander went missing, you certainly had me at "oh god, Ienzo..."
(and I love "damn it Braig!")
seriously, you are doing a wonderful job with this. I was skeptical at the beginning, but this is absolutely amazing. I'm not sure if it's possible to write Xehanort coming back and not remembering anything any better than you have.
and... I have to stop reading at the moment, because I have to go somewhere, but I swear the moment I get home I will start reading this again. If I had a choice, I'd bring my laptop with me and keep reading. (But I don't get that choice... and now I'm rambling, so I'll stop)

I'll have to read the one-shot!

It's nice to see that Isa has home now. Seriously, Sora, how could you let that happen to Isa?

Aqua, at least, won't try to kill Xavier on sight. She knows that doing that would kill Terra.

It seems to me like Xavier is Master Xehanort's personality, before the darkness enveloped him.

How could Sora allow Isa to be so badly mistreated? What the hell, hero?

At least Kairi seems to realize how unfair people are being to Isa. Isa was mean, sure, but he doesn't deserve to rot in prison for the rest of his life when everyone else walks free.

I can't believe that Sora would allow anyone to hurt Isa as bad as you've implied he was hurt. Sure, he hated Isa, but not THAT much.

Ah, The World That Never Was. Xavier had better hope that no one is there.

Xavier seems to have a lot more in common with Terra than Xehanort. What does Xavier look like?

Uh oh. Looks like "Xavier" is gonna get his wish.

I'm guessing that he de-aged, since Xemnas is definitely NOT a kid.

Woot! It's finished! Oh...it's over...that's bittersweet. Well, I'm looking forward to a one-shot where Terra gets a replica he can use so he can go home. That's obviously where you were going with this, but since that's more Terra's story than Xavier's, I can see why you'd leave it where you did. Actually, that's a nice way to end a fic.

I'm really glad I gave this a try when I did, because that allowed me to read this awesome plot and got me reading your other stories too. I really love all these, so I'm looking forward to more from you _

Wow, I like that you were basing the entire fight on actual moves. It made it seem much more realistic. And I actually haven't used even half the abilities you wrote in XD
