Chopper "C1-10P"

About

A beat-up, patched together astromech droid dating back to the Clone Wars, C1-10P — or Chopper —is a reliable droid who has served with Hera Syndulla for decades. Loyal to a fault, with a cranky personality to match his weathered finish, during the age of the Empire, Chopper served the Ghost crew in everything from ship maintenance to undercover missions and combat.
