Xigbar (シグバール, Shigubāru?), the "Freeshooter" (魔弾の射手, Madan no Shashu?, lit. "Magic Bullet Shooter"), is the second member of Organization XIII. The character is voiced by Hōchū Ōtsuka and James Patrick Stuart in Japanese and English respectively.[11][13] His original self was named Braig (ブライグ, Buraigu?, misspelled as Bleig in the North American version), a man with a profound interest for the Keyblade who allied himself with Master Xehanort. He encountered Terra and engaged him in a battle using his weapons the twin Arrown guns, which ended up with the left side of his face scarred and sporting an eyepatch over his right eye. He later appeared at the Keyblade Graveyard, battling Aqua after being glared at by Ven for mocking them. After returning to his world, Braig is the first of Radiant Garden's residents to find Xehanort, befriending him as they became apprentices to Ansem to begin the next step in their plan.[14] Because of this fact, Xigbar is the only Organization member who knows Xemnas' true intentions, but believes he'll fail in being one with Kingdom Hearts.[15] Xigbar controls Sniper Nobodies, and attacks with a pair of Arrowguns called "Sharpshooter" (シャープシューター, Shāpushūtā?), which can be combined to form a sniper rifle. Xigbar can also manipulate space to teleport himself, warp his bullets, and levitate in battle.[7]

During "Kingdom Hearts 358/2 Days", Xigbar has an interest in Roxas and drops several hints about his true nature.[16] He finds out about the Replica Project much sooner than most of the members, and takes it upon himself to monitor Xion.[17] Xigbar battles Roxas at the Olympus Coliseum in the middle portion of the game to test his strength during a mission, much to the chagrin of the latter.[18] Later, while assigned in Wonderland with Axel and Xion, Xigbar fights the latter as she leaves the Organization, smirking how she assumed the form of Ventus from his perspective.

In his next chronological appearance, Xigbar appears at Hollow Bastion near the beginning of "Kingdom Hearts II", though he never takes off his hood as he compares Sora's glare to Ven's. During the player's second visit to the Land of Dragons, he transforms a dragon into a Heartless, and leaves after Sora confronts him in the Emperor's Palace, summoning his Nobodies to cover his escape. In the World That Never Was, Xigbar confronts Sora again, confusing him by calling him Roxas and cryptically mentioning his three predecessors. Xigbar fights Sora's party, and after they defeat him, he fades into the darkness, refusing to clarify to Sora the mystery of "Roxas".[19]
