I made these awhile ago and don't know why I've been holding off on releasing them, but now is the time. They have been seen in the background of some other ships' scenes. The TIE Panic Mk1 and Mk2 are droid fighters designed to be cheap defense fighters for larger craft.
Both lack hyperdrive and carry only the most rudimentary deflector shield that only displaces objects smaller than 6 inches.
The Mk1 is the original design, both in reality and in the universe, of the TIE Panic. It's called a TIE Panic because when you see one it's a panic, lol, but also because when you see a swarm you panic.
In universe when commanders and admirals analyzed the fighting pattern of the TIE Panic they realized that it didn't need the extra wing span in the back. The added weight cause decrease in maneuverability in space and a larger target. Though in an atmosphere it performed well. Thus the MK2 was made with shorter wings, really I just thought the MK1 looked too much like what it is, a reverse wing of the TIE Phobius. The MK1 is still used in atmosphere to defend basses while the MK2 replaced it's predecessor in space, being less expensive, more maneuverable, and an overall better space fighter.
