When I think “Robot Dragons,” I picture the different type of dragons I know of. There’s the stereotypical medieval dragon, the asian serpentine kind you see in parades and art a lot, and then I tried combining elements that are dragon-ish like bat wings and a cobra’s head. At this point it gets more cyborg than robot, unless that head is mechanical. It’s an interesting idea engineering a creature. I saw a special where they discussed devolving birds into dinosaurs versus crossbreeding other animals. Then I think of the times in film and literature where other things are viewed as dragons like construction equipment while demolishing a home. Like anything else, the design comes down to the story behind the dragon. Who made it? Is it advanced or primitive? Aggressive or friendly? These are things to consider when brainstorming.
