RID Undertone model sheet

Undertone is Ratchet's ninja-like Mini-Con partner in Transformers: Robots in Disguise.


When Ratchet was expelled by sending him to capture war criminals, he got help from Undertone. He is very silent type. And when they and Bee Team met Toolbox they began to capture all Decepticons of Decepticon Island. And when the mission was completed, Undertone, Ratchet, Toolbox, Windblade, Optimus and the other Alchemor's prison guard Mini-Cons went to Cybertron and took all the Decepticons of Decepticon Island to Cybertron.



  • Despite his toy being a Cyclone-style Mini-Con (and the only Autobot among the Cyclones in the American portion of the toyline), the cartoon depicts him as a buzzsaw-type Mini-Con like Slipstream and Jetstorm.
