Kingdom Hearts Birth by Sleep
At an unknown point in time, Sïa's heart was consumed by darkness, turning him into a Heartless. However, his strong will gave him the ability to continue on as a Nobody: Saïx. Some time later, Organization XIII found his Nobody, who received the name Saïx and was inducted into their ranks as Number VII. It is known that he joined alongside Saïx's complete being, and the two had a secret, unknown plan. At some point during Kingdom Hearts Birth by Sleep, he has a conversation with Ventus, along with Lea.

Appearance
Sïa appeared in a recent trailer for Kingdom Hearts Birth by Sleep, wearing a short-sleeved blue training jumpsuit, with a crescent moon mark on his left chest. In it, he looks about the same age as Ventus, his hair resembles his Nobody's style, but shorter. Saïx's X-shaped scar was not shown on his face.
