R2-D0
From Wookieepedia, the Star Wars wiki.
R2-D0 (Artoo-Deo), or Deo, was Tiree's R2-model astromech utility droid. Deo managed to escape from the various scrapes Tiree was caught in, and assisted several groups of Rebel agents in rescuing Tiree.
He also helped rookie Rebel pilots navigate the abandoned mine within Mesa 291 on Bothawui and contained coordinates to rendezvous with General Lens Reekeene's command ship, Home.
