From left to right: Boss, Scorch, Hurricane, and Flash. We'll go in that order.
Boss is a blue car, pretty reminiscent of the 1989 Batmobile with the big intake in the center of the hood. There
He had a pretty unique transformation, up until Drift stole it. He's probably my favorite of the smaller Turbomasters.
Scorch is a yellow truck with a flame job, Botcon actually addressed that he existed a few years back with the repaint of Universe Hound.
Again with the pink windows, nice and unified. His transformation is very Trailbreaker-esque, with a strange headsculpt.
Hurricane is a pretty neat looking car, kind of like those "futuristic" cars from the 90s.
The bot mode ends up nicely proportioned with a nice headsculpt, the pink really works to offset the white I think.
Lastly we have Flash, the Ferrarri look alike. It's kind of funny how you can see his and Hurricane's faces through the front window.
He's also got a unique transformation for the arms that makes him stand out in a crowd (and take up a lot of space in a shelf)
As a whole, this a a pretty neat little subgroup, and when you add in Thunderclash and Rotorstorm, you're golden. Nice late G1 molds that deserve a little love.
With the head from Botcon 2006 Cheetor/Tigatron.
