The name or term "Doctor" refers to more than one character or idea. For a list of other meanings, see Doctor (disambiguation).

Doctor is an Autobot Trainbot from the Generation 1 cartoon continuity.

Doctor (ドクター Dokutā), development code Yellow (イエロー Ierō), is the leader of the prototype Trainbots. As her name should indicate, she is an accomplished medic, being able to weld her own limbs back on in the case of involuntary amputation. She can combine with her fellow prototypes into the mighty G Liner.

Fiction

Train Wars

One of the prototype Trainbots created by Doctor Fujiyama, the unit with the development code of "Yellow" eventually chose the name "Doctor". After three of the finalized Trainbots were activated, Nightbird managed to break out (thanks to the rogue AI, Shadow) and upgrade herself with the technology at Fujiyama's facility. Called into action, Doctor and her Trainbots met with Nightbird before she could run away with the three remaining unactivated Trainbots. After Nightbird escaped her grasp, Doctor combined with her fellow prototypes to form G Liner, but the combiner was taken over by Shadow's cerebro-shell program. The three remaining Trainbots did a last-ditch effort to literally crash into the combiner, breaking him free of the brainwashing. However, Doctor wasn't too happy about the resulting damage to herself and the other prototype Trainbots. The Train Wars: The Origin

Notes

• Doctor is a repurpose of the yellow "Dr. Yellow Shinkansen, Combined Rail Inspection" deco of the Diaclone mold whose original coloration would later become Yukikaze. Her names come from the Doctor Yellow trains used to analyze track conditions, as well as the "Yellowliner" (イエローライナー) designation of the Diaclone Train Robo.
• In actuality, the 0 Series Doctor Yellow locomotive used for Doctor is shaped differently from the 200 Series locomotive used for Yukikaze. Back in the 1980s, Takara could get away with no retooling because the toys were small and simple enough that the lack of detailing could pass for both. By TakaraTomy's admission, a hypothetical modern toy of Doctor would require its own budget to satisfy the analytical eye of fans with access to high-definition photography and the Internet.
