I've been researching a lot of KH2 rumors namely because I'm in love with the series and I run an RPG loosely based off of the rumors (and proved facts) of the next game.

Warning!! Major spoilers ahead for KH2. Most are theory- but there are links to images!


BHK is most commonly refferred to as Sora's Guardian or Sora's "Light" Side. I personally do not think he looks like Sora either, so I figure he would be more a "guardian" type character than anything else. He also has the ability to wield the Keyblades Oblivion and Oathkeeper (Oathkeeper was given to Sora by Kairi- which makes it hard to decide if he IS another form of Sora)

BHK is also rumored to be one of the 4 Unknowns featured in the KH2 trailers "Another Side, Another Story," and "Another Side, Another Story: Deep Dive," Since he wields the followings keyblades: Oathkeeper, Oblivion, and a Kingdom Key (Sora and Mickey already have their own- is this another one? Or is it Sora's?) in these trailers.

Final warning! There are screen captures of the Deepdive video as well as pictures from magazines and previews. Don't say I didn't warn you!

Defintions:
BHK- Blonde Haired Kid
DBU- Duel Blade Unknown

To see pictures of the Unknown he is assumed to be, as well as a few other "proving" shots, click the links below:

For reference: The Oblivion Keyblade and The Oathkeeper Keyblade.

At first I thought DB had too feathery of hair to really be the BHK- but the more I watch the trailer and then watch Deep Dive the more I'm convinced that it's him. But that will always be debateable. Some people think that's it's Sora- though I believe that theory is ruined since in the "Another Side, Another Story" you see the DBU full-screen ask "Where is Sora?"

Why would Sora ask for himself?

Oh the possibilities!

I hope that helped.

*sigh* Yes, more spoilers ahead for KH2 and KH:CoM




Edit: Oh and I heard somewhere that Namine was supposed to be in the second game. I'm not sure if she was on a characater list or if it was just a rumor that popped up. Though I know I read it somewhere. Don't take my word on it though- but I hear Sora or Riku (not sure which) has some unfinished business with her. Hmmm...
