Der Roboter-Lord

This is a robot, evil, emperor or something. (my first project I made) blah blah blah evo robot emperor in his mothership thats guarded by robots, but you pass them by fighting them because you're cool and awesome. now you're in front of the emperor of robots ho destroyed earth, super earth forever. robotics scums never. anyways this might be hard. you're also the leader of them. Backstory I guess: uuh you used to be a greatest destroyer of aliens or something until the alien emperor made a robotic suit. then turn cybernatic. he and his alien army invaded your planet and now you're gonna kill him in the finale or try to.
