Plix

"There are Suthers and Plix."

- Tana Chellaine recognizes Plix's holo at the Last Angle

Plix was a pilot who flew for the Galactic Empire out of the Imperial Bright Jewel Oversector Flight Base located on the moon Axxila III. Plix was killed sometime prior to the Battle of Yavin, and a hologram of the pilot was put up in commemoration in the Zero Angle, a bar built in the Flight Base. Shortly after the Battle of Yavin, Plix's hologram, along with that of another pilot named Suthers, was recognised by Tana Chellaine, an Imperial Army TIE fighter pilot who flew in Nashtah Squadron.

Behind the scenes
Plix was first appeared, although only as a hologram, in Last Call at the Zero Angle, a short story written by Jason Fry and published in Star Wars Insider 156 in 2015.
