- "Artoo? What happened? I can't see!"
- ―Luke Skywalker, taken the effects of a flash grenade
A flash grenade was a type of non-lethal grenade which, when activated, created a bright energy flash and loud noise to disorient opponents. It also gave a mild impact although it was not as destructive as thermal detonators, and was capable of disabling droids for a short period of time. When Luke Skywalker went on a mission to Ben Kenobi's home with R2-D2, Boba Fett ambushed them with a flash grenade in an attempt to capture the boy.
