In KH2 when you're about to fight Xigbar, he says this

 

"You really but the organization in a pickle. Guess that's why the Keyblade chose you. But man did it pick a dud this time. You don't look like half the hero the others were"

 

Xigbar's talking about Terra Ven and Aqua from BBS.

 

Mostly Ven becuse he merged with Sora at the begining of BBS so tht makes him half of Sora. Get it?

Yeah I get it, it was pretty much confirmed that when Xixbar said "You dont look half the heroes the others were" he was talking about Ven, Terra, and Aqua. But Xixbar was kind of wrong because (spoiler!!!!!!!!!!!!!!!) Ven is inside of Sora's heart. I don't think that Braig, Dilian, Eleaus, Even, or Ienzo knew about any of the out comes of Ven, Terra, or Aqua, well maybe except Braig (100th post )

Nobody knows that Sora's heart merged with Ven's. Now that I think about it, Sora doesn't even know who Ven is. So Xigbar really shouldn't know anything about that.

When I first played KH2 I always wondered what Xibar meant by that. And then later I found out by myself that it was the BBS charatcers

i noticed that to but i was like why does he keep bringing them up lol so when I heard bout bbs searched up a bit then i noticed

Yeah, this was pretty obvious. Though I'm guessing he was referring more to Terra and Aqua since he actually fought them and only interacted with Ven when he was frozen. And nobody knows about Ven's heart merging with Sora's.

This has been noticed for so long ago...

 

And nobody knows that Ven merged with Sora, so Xigbar properly didn't mean especially Ventus.

I think he meant simply for Roxas, because later on he always babbling about Roxas, and Roxas betrays them. It doesn't seem that they talk anything bbs in kh2. It's said that bbs concept is there since kh2 fm so I don't think there's isn't any in original kh2, it was purely about Roxas and Sora. So I think.
