Wedgehog was a lightweight robot that singularly participated in the first series of Robot Wars. At the time, it was actually a Middleweight. Wedgehog was substantially lighter than the rest of the robots in its heat; it defeated Dreadnaut in the Arena, which was 64kg the heavier. However, it lost in the heat final to Robot the Bruce. Its name, like Kronic the Wedgehog's and Edge Hog's, is a pun on hedgehog.
