These were posted to my Rescue Bots Facebook page by Marvin S. Mariano. He also did the Dinobots designs as well.
So Blurr might've originally been Smokescreen (going by the concept art colours)? Or, and go with me here, Perceptor? They could give him a really high handle-like spoiler and pretend he's a lawn mower. Call him Trimmer. Or The Trimson Warrior.
While not as cute as the final design, I like the concept art that makes Servo look like a Swiss Army Knife.
This concept art is way cooler than what we got. Shame to see that Hasbro just didn't care about what they were given.
Seriously these new Rescue Bot (Rescan Line) Toys are garbage. The joints are so loose and the springs get sprung (especially the Blades the Flight Bot Fighter Jet). The last great Rescue Bots were Medix and Hoist. Everything since the Energize line has been utter garbage, unfortunately!
I doubt that they originally were planning to do Smokescreen...since he's already appeared in Prime and did not have that deco.
Personal opinion I guess. I've gotten every $9.99 figure since then. They've all been pure joy, and I've had 0 QC issues.
