Bluestreak torso, arms, and doors.

One 1x1 + clip black element.

Biker hands from the Wheeljack/Knockout human Kreon.
I've had a hankering to make him a little more accurate by painting the helmet blue. I've also considered swapping the torso and arms for one of the dark blue police officers, but then I would have to paint both the helmet and the doors to match; plus I would lose the car chassis decal on his chest...so this will be my skids for now. I figure he is about as accurate to skids coloring as a lot of the official Kreons get. (Bluestreak's white pants, anyone?)
