The named pilot representing the player character in Star Wars: TIE Fighter tie-in material is Maarek Stele.
TIE Fighter, released by LucasArts in 1994, does not identify the player's pilot by name during the game itself. The name Maarek Stele comes from the accompanying novella The Stele Chronicles and from Prima Publishing's official strategy guide, which provide a background story for the Imperial pilot whose career the player controls.
Stele begins as an Imperial recruit and rises through the ranks by flying increasingly advanced starfighters. The game places him in campaigns involving Rebel forces, pirates, rogue Imperial officers, and Grand Admiral Thrawn. Its unusual perspective presents the Galactic Empire as the player's side, making TIE Fighter a notable contrast to the Rebel-centered X-Wing games.
Ace Azzameen is associated with X-Wing Alliance, while Keyan Farlander is the player character linked to X-Wing. Dash Rendar is a character from Shadows of the Empire, not TIE Fighter. Maarek Stele is therefore the correct tie-in identification, even though the original game itself uses an unnamed player avatar.
