I've read that the suit design from the series Space Sheriff Gavan was a heavy influence if not the outright inspiration for the suit design in the RoboCop movies.
It's only appropriate, then, that there's at least one series from the Metal Heroes franchise, Jiban, which is actually more or less directly based on RoboCop.
Because RoboCop totally fought rhino monsters, demon things, and wizard ladies, right?
(On a different note, this scene was clearly the direct inspiration for a scene in the surprisingly exquisitely written Brave Robots series J-Decker, which was about a giant robot cop that transformed into a police car. Because Japan, of course.)
