This is a repaint and mod based on Cybertron Clocker. I quite liked the fig, but the colourscheme was hideous, and I didn't like the weapon, cyber-key gimmick, or the massive exhausts. So I stripped them all off.
Since for Fusion I want a significantly higher proportion of Decepticons to Autobots, I had a rummage through my MTMTE for inspiration, to see what character I could turn him into. I settled on Blackjack.
I took Clocker apart, dyed as much of him as I could black, and set to repainting him.
I made a couple of minor mods along the way - building a spoiler, and filling in his chest detail using PVA; this was to help the chest resemble a vehicle hood, like his G1 form.
The spoiler was made using a strip of thin styrene, held round a former (in this case a plastic film canister) with rubber bands, and heating it with a hair dryer. After it had cooled, I removed it, cut it in half, and used small pieces of thicker styrene to make the supports and end pieces.
Here's the result. Hope you like it!
