Moff Gideon's Outland TIE fighter.
The Outland TIE fighter was a class of TIE line starfighters that was used by an Imperial remnant after the fall of the Galactic Empire. It had wings that folded when landing on a levelled surface, allowing for ease of access to the cockpit and creating a distinctive form not dissimilar to that of an X-wing starfighter with its S-foils in a closed position. Otherwise, it looked exactly like a standard TIE Fighter.
One of these ships was used by Moff Gideon as his personal starfighter.
