They were present in the Battle of Christophsis, where they guarded the shield generator. Anakin Skywalker and Ahsoka Tano breached the defenses, although their progress was neutralized as their mine field was completely activated. Ahsoka sped passed, as her master became the bait. The generator was then bombarded with charges, just before Ahsoka turned, pulling down a wall around Anakin, crushing the droids.
The droids were brown orange. They had a broad, cylendrical front which connected it to all four limbs, two arms and legs. On either arm was a duel turreted racke that could pivot to shoot accurately.
- The Retail droids were inspired by Droideka or Destroyer Droid concepts.
