What does he mean?

On http://kingdomhearts.wikia.com/wiki/Kingdom_Hearts_Re:coded, they wrote this:

"Realizing that not just a "single" Xehanort has returned."

Also, in the Re:Coded Secret Ending, Yen Sid does talk about Xehanort and someone else.

What does this all mean? Two Xehanorts?

I don't think so. Maybe he's talking about Vanitas. Who knows? Maybe Xehanort could ''revive'' him. Or he could return with the Organization's somebodies. Who, of course, were seeking revenge.

Yeah, he meant that there will be more than one Xehanort to appear. Like there will be different forms of Xehanort that we should see in KH:DDD.

i was just about to make a thread about this cuz i just unlocked the secret episode 2day but i was thinking maybe he meant that he would hav terra on his side as well!!

"Would a single one of you suffice if what you faced was not a single one of him"-Yen Sid

 

Yup he meant that there will be multiple Xehanorts.

u never know he may come back with the heartless & nobodys(cuase didnt ansem{his heartless}control the heartless and xemnas{his nobody} control the nobodys??? there might have even found a never enemy to team up(idk unversed) with i all so think he will be back with at least 3/4 of the members i highly think its likly to be briag(xigbar) is going to return,i also wonder & i now its off topic but if terra was to be returned from master xehanorts hold would eraqus return too?or no cuase we dont knpw the wear abouts of his body(if he went some were or not)
