My version, I used the same name pattern, with the nickname, then the actual name, detailed the attacks a bit more, and also turned its tail into another leg :)
It jumps REALLY high, about as high as a robot on a jump pad, its attacks include a charge that knocks you down, if you are knocked down, it will catch you, and bite your face off, soooo... a pretty SCARY opponent, specially if you don't have the Get Up upgrade, but, if this thing knocks you down, you'll have to wait even with Get Up, but with it, your knockdown time will be halved. It has a silver colored MK2 version. It is a robotical version of a badger, thus it was used by the robots as a torture machine against captured humans so they could give info about other human colonies.
Full name: MK1/2 "Hopper" Torture Automaton
Yeah, when I was building it I tried to make its mouth functional, but I'm not really good with redstone, and I'd rather not mess with commands in that thing, so I ended up ditching that, then, when I finished the mouth I realized there was no space for the eyes, so I made a pretty creepy "Separated eyes thing", and it got the result I needed! I wanted to make it pretty scary, because of the backstory (I guess, that if you want a torture robot, you should make it as scary as possible), and it turned out pretty good!
oh.. about that uniqueness... "The Hopper(with tail)" is actually the answer to a question: can I design a doborog enemy?
no.
This robot looks amazing! I think now you should try to make a regular humanoid robot, but first, a question:
In which version are you playing?
Then have this: https://www.mediafire.com/?2j5xt0i3094ac55
To install it into your world, go to the .minecraft folder, then go to saves, after that, open the world save folder where you want to put this template, there should be a structures folder, but if there isn't, create one by typing "structures" without the quotation marks, after that, go into this world, and type the following command: /give @p structure_block
Then, place the block down, right click it, and press the [D] until it becomes a [L], then, on the top box, type the following word: Robot
After that, press LOAD, then, a boundary will appear where the structure will be generated, then, click LOAD again, and watch the basic template of a humanoid robot being generated!
