Mini-Doras are small robotic clones of Doraemon, manufactured by the Matsushiba Robot Factory for the Time Patrol to honor Doraemon's role in capturing terrorists Dolmanstein and Black Mask. Serving as Doraemon's helpers, they feature his iconic cat-like design in miniature, distinguished by different paint jobs. Common colors include red, green, and yellow, though their number and prominence vary: the 1979 anime displays three distinct colors, while the 2005 anime primarily features a red variant.

These sentient automatons perform diverse tasks. They communicate in their unique "Minidora" language but understand human speech. While capable of operating gadgets, their effectiveness is limited by size compared to Doraemon or Dorami. They exhibit agitation when called "raccoons."

Mini-Doras appear across official media. They debuted in the 1979 anime and appear in the 2005 anime's opening. Yellow and green Mini-Doras made their first film appearance in *Doraemon: Nobita's Treasure Island*. *Doraemon: Nobita's Secret Gadget Museum* reveals their origin in a plant-like machine within the Nature Hall. A red Mini-Dora stars as the protagonist in *Mini-Dora SOS!!* and serves as an instructor in the DS game *Nobita and the Green Giant Legend*. Within the spin-off *The Doraemons*, the character Dorarinho relies on Mini-Doras to access gadgets due to lacking a traditional four-dimensional pocket; Dorarinho's Mini-Doras are depicted with ears.

Cultural adaptations show variations: the Hindi dub portrays them as non-verbal, using sign language. The Turkish dub features some with speaking capabilities and deeper voices. In the Indonesian dub, they speak Indonesian in the 1979 version but align closer to the original Japanese vocalizations in the 2005 adaptation.
