Braig
Terra gave Xigbar the scars and took out Xigbar's eye in a bad fight.
xigbar is 30 years old.
Aqua actually doesn't save Ventus from freezing. Instead, during her fight with Xigbar's nobody Braig (in Aqua's story), Ventus manages to thaw himself out.
No one knows, Xigbar's human self is Braig, but his heartless is not shown in any of the game series. He probably ended up like Sora, having a shadow heartless
His real name is Braig. Xigbar is an anagram of this name with an 'X' thrown in it. His name was misspelled as "Bleig" in the North American version of Kingdom Hearts II.
Xigbar sees Xion as Ven because in the past, Xigbar or Braig has seen Ven, and because Xion's appearance changes depending on the viewer's relationship with any of the people connected to her, Xigbar's view of Xion is Ven. also i think the reason xion has a memory or relationship is because in Birth by Sleep Ven goes to destiny island and meets sora, and as you should know Xion has Sora's memorys
You have to kill Xigbar in The World That Never Was
Xigbar/Braig
you should at LEAST be at level 50 to do it quite easily
Ha! You would thnk that Xemnas would be right hand man instead, but yeah, it is Siax. Well, its Siax because he's like Xemnas's suck up. Lol. And Xigbar is just plain stubborn, so he cant be right hand man. But Siax isn't hard to beat, Xigbar is. So i don't understand it either. =)
No just Xaldin
In The World That Never Was, after you defeat Xigbar and meet up with Riku
