I've wanted to create an movie version of Prowl for a while now and Roadbuster's alt mode made perfect sense to me: Chevrolet Impalas are used by the Police and NASCAR vehicles are essentially modified Impalas. (Plus, Roadbuster has those shoulder-mounted rocket pods, which seemed like a natural fit for Prowl.)
The custom head was fairly straightforward to make, cutting off unwanted mulletness and moulding Prowl's distinctive helm from Milliput. I took care to ensure everything still fit when he transformed and only had to trim a little plastic from his legs to enable his new noggin to slot into place.
After that, it was down to considering various Police liveries: I decided it was best to base him on the original toy, which allowed me to use Prowl's Reprolabels (for both G1 and Classics) rather than try to located appropriately-sized, generic Police decals.
The tricky bit was finding a light bar to match, but fortunately, I found a 1/38 scale diecast toy, from which I was able to liberate the required item.
The final touch was giving him more suitable guns rather than Roadbuster's chainsaw. These were taken from his fellow DOTM Wrecker, Topspin (who seemed to have guns to spare). These can either be hand-held or mounted on his forearms using the Mechtech ports.
(In fact, as the lightbar has been mounted using the rooftop port, this can also be swapped out for one of his guns for more explodey fun! This also means you can put his lightbar on either one of his arms but... I don't know why you'd do that?)
BOOM!
