VAT are keyblade trainies and they use real keyblades but only get KC's when they pass the academy. MX is tainted by the Darkness and leaves with Xehanort his apprentice and Vens best friend (This is a theory of mine if you want to see it is titled Ven and DS friends) The two leave for the darkness. Eventually MX sees that the darkness is evil and also relizes that Xehanort is gone to far. He then asks VAT to correct his mistake of bringing his apprentince into darkness. Ven leaves to fight on his own and is quickly beaten and then mickey and the others come to help. After a long fight it is just down to DS and Ven again they continue to fight and just as Ven is about to be beaten MX throws himself in front the attack and is slayed. Ven IS PISSED and goes into a rage pumbles DS and "kills" him But what really happened was DS opened a portal to a random world and escapes but not without losing his memorys due to being beaten up. So Ven doesn't see him and assumes he killed he and is overcome with grief and then asks Terra and/or Aqua to erase him, they grant his wish and take his heart place it in Sora. Well that was long! Now I will go to my fire proof dome for 2 days.
