N-13

N-13 (also designated CT-27-5555) was a human female clone of Clone Wars veteran CC-7567 (Rex) who trained as a Null-class ARC trooper under Sergeant Darman Skirata and ARC trooper Commander Echo. During her training she took the nickname Fives and built a strong relationship with ARC N-7, she was later adopted by Echo.

Early life
Fives was born on Kamino during the Second Great Galactic War. She was discovered at the age of six-months by her former commanding officer CC-7567 and sent to Sergeant Darman Skirata for training. While under his care she began to experience Force-visions of her mission to Lola Sayu during the Clone Wars.
