I'm inorganic--not a robot, nobody built us, but made of metal and cabling and neurocircuitry. About five meters tall, red and white plating. [Ratchet shrugs a little.] Not particularly exceptional other than that. My optics were the same color as my eyes are now, which I gather is sort of odd. And I was a surgeon, back home, just--you know. Not a human one by trade, though I've had prior experience.
