Figure: Luke Skywalker in Storm Trooper disguise
Unmasked head: BBI
Gear: Marauder and BBI

Storm Trooper IDG477 received the nickname 5 because he was the youngest of five brothers to join the Imperial ranks. No one knows exactly why he chooses to go by Bob after the team was stranded on Earth but no one questions it.

Bob is a highly skilled sharpshooter. Able to hit targets that others only dream of. He knows the running joke that Storm Troopers can't hit anything. He also knows when Storm Troopers miss it is on orders from above.
