Okay, so you know how Vanitas looks like Sora because Ventus merged with Sora's heart; well I found something else in common between the two. Now I don't know if anyone else noticed this(so pardon me if it's already well-known), but Sora and Vanitas have similar music that goes with them. First, listen to one of the themes that plays during some of Vanitas' battles(specifically from 1:46 to 2:07). Then, compare it to Sora's theme. I just thought it was kind of neat because it kind of shows how connected Sora and Vanitas are.

Yeah, this is pretty well known at this point. ñ_ñ

There's also Roxas' and Ven's themes in there.

I think we all knew that. Or, at least, I did

I really love Vanitas's theme! I'm constantly listening to it. The way Roxas, Ven and Sora's themes blend together into Vanitas's battle theme. IT'S EPIC!!!! I can't even describe it.

yea this da truth. i always thought they were related in some way or something

._.

One of the best battle themes of BBS, I agree with all people here there is no mistery here, also i like to see Vanitas again... ( That of course if nomura finally bring us KH3 SOON)

We need to get you a time machine.
