The Mauler 51-50 MiniBot.
Mauler 51-50 was one of the 50 robots that got into the MiniBots line. This one is one of the least accurate, being dark grey, having no decals whatsoever, and having an incorrect screw design on top, though this could've been due to the manufacturer being on a tight schedule. It does, however, contain the padlock flails that the real robot used. Oddly, the card which came with the toy featured the original Mauler from Season 1.0 instead of Mauler 51-50. Odder still is that the image featured of Mauler 2000 is not an official photo, but rather an edited event report photo taken by Jim Smentowski.
