Dicer

Dicer was a human female pilot who flew with the rebellion under the callsign "Phoenix Six"[1] in the third year before the Battle of Yavin.[2] She was a lieutenant in Phoenix Squadron, a fleet composed of A-Wing starfighters, and operating under the command of Jun Sato. During her deployment at the recently established Chopper Base on the planet Atollon, Dicer was tasked with placing a sensor on the eastern end of the base for protection against any unwelcome visitors. After placing the sensor, Dicer was taken by a krykna, a spider-like creature native to the planet. Dicer's disappearance was reported to Sabine Wren, who decided to go looking for her with the help of retired clone trooper Rex.

Behind the scenes
Dicer appeared in "The Mystery of Chopper Base," an episode of the second season of the animated television series Star Wars Rebels. She was voiced by Ashley Eckstein, who also plays Ahsoka Tano in the series.

Captions misspelled her name as Deiser, but the databank marks her as Dicer, and the Databank shows canon information.
