A sly and fearful personality from an ancient alien archive that takes over Data in 2370 and warns the crew about the sun queen Masaka.
Ihat is one of many characters stored in the D'Arsay archive. He appears in the episode Masks and is played by Brent Spiner, since he speaks through Data.
The Enterprise-D finds an old structure hidden inside a comet. It begins to change the ship into a copy of its makers' world and fills Data with the figures of their mythology. Ihat is the first to speak at length. He is quick and mocking, and terrified of Masaka, whom he says is waking.
Picard questions him to learn how Masaka can be dealt with. Ihat offers hints about her temple and about the one being she fears, but he vanishes whenever he feels her drawing near, and other personalities take his place. His scraps of information help Picard to build the temple and call Masaka out.
