Here is my take on Prime Dead End. Did him up last week, and just got home from business trip. "Long exposure to the radiation of Dark Energon has changed DEAD END. The formerly talkative DECEPTICON mercenary now broods quietly in the shadows, staring hungrily at the power cores of his fellow warriors. He’s always freaked out the AUTOBOTS, but now even his friends think he’s scary. And that’s because he is. DARK ENERGON has unpredictable effects on anyone it touches. With DEAD END, that has resulted in him feeling a hunger that normal fuel does not satisfy, and an attraction to the darkest places in the DECEPTICON base." Reading the bio and seeing the figure had a complete lack of Decepticon purple, I figured Id just add a lil bit of detailing and such. Used a paint marker. I left the wings up a bit in car mode to create a air scoop.
EDIT: SO I finished Dead End. I added more detail, such as purple shading as well as more detail around the hood and legs. I'm starting to get a wild rider vibe from this figure now!
