Ratchet is the Autobot's chief Medic. She has a bit of a bad temper, and she'll go from happy-as-can-be to furious if you just so much as look at her the wrong way. Though most bots don't blame her, she's been through a lot, the war has never been too kind to those just trying to keep everyone alive. She also likes to dabble in the science/engineering side of things, though not officially trained for it, she does find solace in her various projects. (And yes I have genderbent this version of the character)
