R8-B7 is similar in appearance to any other astromech droid featuring dark grey legs and body with printing similar to that of R3-D5 except in gold. The dome is earth blue with mostly gold printing.
R8-B7 was Mace Windu's astromech droid during the Clone Wars. He co-piloted Mace's Delta-7B Aethersprite-class light interceptor. The droid was destroyed on Vanqor by two gundarks while Mace Windu and Anakin Skywalker were searching for survivors at the crash site of the Endurance after it crashed there. Boba Fett took down the ship in an attempt to kill Windu to avenge the killing of Jango Fett.
