Total scratch build. For obvious reasons, Frenzy was the only character in the live-action movie that didn't get a decent toy besides the FAB. The more I watched his characteristics and personality in all his scenes, the more intrigued I was with the efficiency and rawness of his design. With this in mind, I decided to prove to myself that it was in fact possible to recreate any character I wanted--no matter the size or complexity...and Frenzy was the perfect challenge. I brought this little nightmare to Botcon 2008, and the best part was on Sunday when people gathered around the table to see his transformation back to radio. Strangely though, I dread his transformation so I rarely change him back to his alt-mode. The robot mode is the most rewarding, with the alt-mode fairly decent. Here's his features: Frenzy is about 30" tall standing straight up & weighs about 5lbs. He has around 70-points of articulation and has almost limitless posability. 4 leds for the eyes. (also posable) There is a small battery-powered motor on the back of his head which makes his head vibrate convulsively like in Air Force One, which I call "The Download Feature." He has a working speaker which you can plug your mp3/cd player into and play music through. One of my favorite features, he is made to fit Soundwave perfectly inside his chest, a funny role-reversal gimmick I threw in. Frenzy was made with mostly (aluminum angle, flatbar, threshold, fence-ties, channel & tubing) nuts, bolts, rivets, washers, finishing washers, springs, brass-couplings, door keys(yeah, door keys), speaker grills, furniture slides, romex wire, phone-line, leds, an X-box controller motor, styrene, Bionicle joints, ABS panels and various Radioshack electrical apparatus.
