Mixmaster

Nothing is safe. From raw ore to living robots, it all goes into Mixmaster's grisly drum where it's reduced, refined, and recombined into virtually any raw material the Decepticons need. Watching Mixmaster prepare a new batch of materials is like seeing some mad alchemist at work, giggling and cackling over his creations with evil glee. It would be a stretch to call him a scientist; a better comparison would be to a witch throwing arcane scraps into her cauldron to complete a bubbling potion. His fellow Decepticons suspect Mixmaster of having a few wires loose in his logic center, but they can't argue with the results. He transforms into Devastator's left leg.
