Sneaky

Sneaky, the R9-series astromech droid belonging to Jaina Solo, served as her StealthX starfighter's unit during the Swarm War. During the Battle of Tenupe, Sneaky met his demise when Jagged Fel downed Jaina. Subsequently, Sneaker became Jaina's new R9 unit.

It seems that another droid, also named Sneaky, was utilized by Jaina in the Battle of Uroro Station. It is believed this droid was obliterated when Jaina's StealthX was bombarded by turbo lasers originating from the Anakin Solo.
