I've yet to see anyone do this mod so i figured i would show how to do it. Things you need -1x Optimus Prime -1x screw driver -1x pliers -1x screw (with washer) First remove the top part of Prime from the bottom. Next disassemble the grill/lower torso. (don't lose the screws!) Note the grill detaching it's not supposed to but i made that a mod so use it if you want. Now remove all the gears with the pliers do what ever you want with them. (sorry no picture for this step because i did the mod a long time ago) After that take the new screw and screw it into the the middle of Prime. Once you do that you can reassemble him. And finally you've gotten rid of the gimmick but still retained everything else. So I hope this helped and changed your opinion on this prime toy.
