Berl was an Imperial stormtrooper stationed aboard the superweapon known as the Tarkin in 3 ABY. He confronted the Rebel droids C-3PO and R2-D2 as they were attempting to sabotage the Tarkins tractor beam generator. Berl threatened the droids only for their Wookiee friend Chewbacca to approach him from behind, pick him up and toss him into the generator, destroying it and killing the trooper.
