Vanitas or The Masked Boy is one of the main antagonists in Birth by Sleep. He is the embodiment of Ventus’s darkness that Master Xehanort unlocked. The keyblade he wields is called the Void Gear.The plan was to have Vanitas -pure dark- , and Ventus -pure light- to forge the ever powerful χ-blade. But Ventus needed to get stronger. Vanitas tricks Ven into going after Terra once Terra leaves and thus playing out the entire story of Birth by Sleep. Vanitas appears through out the story taunting Terra, Aqua, and Ven. Towards the end of the story, Vanitas lures Ven to the Keyblade Graveyard. Once our heroes enter the final battle, Ven is frozen and Vanitas delivers a mighty blow to Aqua and just as he’s about to finish her for good, Ven uses all is might to break free from his frozen prison. This is where Ven and Vanitas finally clash. Once Vanitas is defeated the first time, he reveals he is the cause of all the Unversed. Then Ven and Vanitas are transferred into a Dive into the Heart, where Vanitas is weilding an incomplete χ-blade. To complete it he must fight Ven, but Ven refuses to let it be completed, no matter what it takes. While all this is happening, Aqua and Mickey find a Ventus possessed by Vanitas wielding a complete χ-blade. After the intense battle, with both Ventus possessed by Vanitas and Vanitas wielding the incomplete χ-blade, Vanitas is vanquished, but Ven enters a coma-like state.
Once he is defeated you can play as Aqua, Terra, or Ven to fight Vanitas' Remnant in the Keyblade Graveyard which is a crazy difficult fight. If you defeat him, you obtain the Void Gear keyblade.

One thing you probably noticed was the Vanitas unmasked looks exactly like Sora, only with black hair. Either that’s just a fun coincidence or there is a connection, so when Ven awakens in KHIII will he think Sora is Vanitas?
Another thing is Vanitas was Master Xehanort's right hand man. When Xehanort returns,
he’ll probably want his assistant back, and him being an all powerful Keyblade master he must know some way to re summon him.
And Vanitas controls all of the Unversed. Right now we have Heartless and Nobodies, & Xehanort probably can control them since Xehanort’s Heartless and Xemnas controlled them both before. Having all three enemies at his disposal would make him even more powerful.
Come on Nomura, don’t use an awesome character only once!
What do you think? Am I totally off, will Vanitas stay gone forever? Please Comment with you thoughts.
