I'm kinda busy with these forums today... for some reason I'm thinking Repliku could be Xehanorted...

 

*cough*

I can see you've been busy, lol.

 

Anyway, that's pretty doubtful. None of the Norts knew he existed as Vexen made him as a side project but both him and Repliku were destroyed in CO before Xemnas got any wind of him. In fact, I don't think Xemnas ever even knew Repliku existed. Plus you need MX to actually, you know, "seed" people.  

We're calling them Norts now? Ok.

I think it's possible but unlikely. Xehanort would probably get another Riku from the past instead.

He'll just randomly show up as the 13th darkness.  ^_^

Past Riku is more probable to appear, Repliku was never met by Xemnas. Axel said he was the only one who knew of his exceptional functionality, so Xemnas seems to have never known. So, it's not probable. 

By Nomura logic, anything can happen.

 

 

In all seriousness though I'd love to see Repliku be brought back.
