So shredder in the comic books get killed by Donatello by knocking him off a roof. He comes back by being cloned using some Foot Clan cloning worms and then gets his head chopped off by Leonardo. Then some Foot Clan Mystics revive him again. So I was like well what if Shredder come back as a cyborg. If you can tell me what I used for background music I will make a custom audio clip of your choice.
Also i loved that line from TMNT 2: secret of the ooze where shedder called the turtles "Those freaks!" just such a roll off the tongue sound.
