Ratchet

A Cybertronian Autobot and the crew of the Ark's chief medical officer, Ratchet arrived on Earth aboard the spacecraft that crash-landed millions of years ago. Disguising himself as a terrestrial ambulance, he serves as the Autobots' indispensable field surgeon and repair specialist in their ongoing war against the Decepticons.

From the very first issue of Marvel's landmark 1984 series, Ratchet has been part of the Transformers story since day one — a Bronze Age original who was there at the beginning and has never stopped showing up. Across more than four decades of publishing, this character has logged 65 catalog appearances and can claim two key collector issues, a testament to genuine staying power in one of comics' most beloved licensed properties. Ratchet keeps remarkable company, sharing pages with heavy hitters like Megatron, Starscream, Soundwave, Bumblebee, and Wheeljack across titles including the classic Marvel run and the crossover spectacle of G.I. Joe vs. the Transformers. If you're building out a serious Transformers comics collection, a character with this kind of debut pedigree and this much history is absolutely one to know.
