William has the ability to "see what X.A.N.A. sees" on Lyoko. All he must do is shut his eyes, and X.A.N.A. will give him a mental image of his target or objective. It is a bit similar to Aelita's Second Sight. It is unknown how often William uses this power, as he was only shown using it once in Opening Act. It is unknown if the power was derived from X.A.N.A.'s possession of William, or if it is part of his original Avatar.
Most fans refer it as Far Sight. However, the official name is given in the Facebook game.
