Second in my skin series based off the Transformers masterpiece figures is the Autobot scientist/inventor-of-things-that-go-kablooey, Wheeljack! The "ears" that he has were kinda difficult to do, but i think this does it justice.
(Also, yes, i included the face easter egg :D)

Info on Wheeljack: (From www.tfwiki.net)

"Wheeljack is his own worst enemy. Something of a crackpot inventor, a good half of his creations blow up in his face, and that's just if he's lucky. He's simultaneously one of the Autobots' greatest assets and problems; for every successful gadget he builds, there's one which requires Ratchet or Hoist to put him (and his lab) back together. But once in a while he strikes gold, which has won him respect from even the Decepticons. "

Of course, if there's any of the Masterpiece figures that you want me to prioritize in minecraft-izing, let me know in the comments!

(And no, the JK in my name does not stand for just kidding)
