225 was an astromech droid of the R-series line and belonged to a Gran merchant located on Pantora. Under the supervision of the protocol droid known as CG-67, 225 worked alongside DK-3, another astromech droid, and Clink, an LE-series droid. 225, together with the other droids, provided aid to the clones of the Bad Batch when they needed to fix their starship, called the Marauder.
