"For some unknown reason, Braig has a larger part in this game than the other five of Ansem the Wise's apprentices, except for Xehanort. Before fighting Sora in Kingdom Hearts II as his Nobody Xigbar, he mentions that Sora wasn't even half the hero that the "others" were. By this, Xigbar was refering to the three heroes from Birth By Sleep: Terra, Ven, and Aqua. This shows that Braig did meet the three heroes sometime. Also, while about to fight Xion in Wonderland in Kingdom Hearts 358/2 Days, he is distracted when he sees her as Ven, implying that he has had some memorable experience with the hero."
