A few months back in the "Transformers Dreams" thread, I posted a dream I had about a Post-Great War Cybertron in which the Autobots and pardoned Decepticons were trying to adapt, only for Scorponok to threaten war anew after being convicted of fraud.
A bit back I came up with a whole slew of Spychanger design concepts for something else I was doing, only to realize that they rather roughly match some of the characters in my dream. It only took a little bit of tinkering around to make things fit.
The Great War is over. Megatron has been captured and imprisoned, while several other top Decepticons have either sought clemency, been killed, or have gone into hiding. Peace has come to Cybertron and the other planets caught up in the fighting.
...But it does not last. Scorponok, one of the Decepticons to have been given clemency, finds himself on trial for a number of crimes, including fraud and being a slum lord. The evidence against him is overwhelming, and so he is quickly convicted. Because this conviction will mean that his clemency is overturned, he can now be tried for his crimes during the war. Realizing that this will likely mean life imprisonment or even execution if the full details come out, he instead reactivates his weapons systems and fights his way out of the court building. He successfully links back up with a trio of Decepticon resistance cells, and they spring Megatron on their way off-planet. The motley group now marauds planet after planet, stealing resources and striking at targets of opportunity. Optimus, for obvious reasons, wants the group stopped once and for all, and so has enlisted Fortress Maximus and a large contingent of volunteers for the job.
Optimus Prime -> Airport Fire Tender. If RiD 2001 Prime was George Lazenby, then this one is Pierce Brosnan.
Ghost Striker -> F-117A Stealth Fighter. He not just a Wrecker; he's the star of the show.
Blaster -> Scion XB. Essentially the G1 character.
Slipshod -> Hummer H2. He'll get the job done, even if it's by the skin of his metaphorical teeth.
Dragonfly -> F-19 "slick" concept. It's easy to forget that the pyrotechnics display you're watching is his most recent target.
Sky Knight -> G. I. Joe Conquest. Takes the whole "knights of the air" bit rather seriously.
Raizor -> KA-50 Hokum. Ghost Striker's drinking buddy.
Trailhead -> Snow Plow. Essentially G1 Trailbreaker with a new name.
Hoist -> Semi Tow Truck. Essentially the G1 character.
Moonshot -> Space Shuttle. Essentially Go-Bots Spay-C.
Vector -> F-14. Imagine if Chuck Norris could fly.
X-Radar -> Transportpanzer Fuchs. He's the halfway point between your company's tech support guy and Carlos Hathcock.
Seaspray -> LCAC. Essentially the G1 character.
Freezerburn -> AAVP7A1 Amphibious Transport. Honey badgers don't care, and neither does he.
Ironhide -> F-150. Essentially the G1 character.
Overdrive -> Lamborghini Diablo. The G1 character, but with a hint of X-Brawn.
Camshaft -> Formula 1 race car. The G1 character, but with a hint of RiD 2001 Prowl.
Downshift -> Dodge Viper. The G1 character, but with a hint of RiD 2001 Sideburn. The kid appeal character of the team.
Jazz -> Porsche 911 Turbo. Optimus' head of intelligence.
Roadburner -> Pro Stock racer. The halfway point between G1 Road Rage and Cybertron Override
Prowl -> Ford Crown Victoria Police Model. Essentially the G1 character. The head of Optimus' security element.
Hound -> Generic military jeep. Optimus' forward scout.
Megatron -> Cargo lorry. Doesn't need help running any blockades.
Nitro Viper -> Micro Machines BX-21 Vindicator. It's not the kill with him; it's the overkill.
Soundwave -> Halftrack. Essentially the G1 character.
Paywall -> Aurora spy plane. Soundwave decides what Megatron needs to see; she decides what the Decepticon legions don't need to see... unless they can meet her price.
Starscream -> F-15. More closely resembles the Prime version.
Slipstream -> Micro Machines X3 Raider. Yang to Starscream's Yin.
Boombomber -> Artillery track. "Able to blow things up" defines his entire skill set.
Greejeeber -> Gaz Tiger. Essentially Go-Bots Jeeper Creeper.
Rage -> Supercar. Essentially the G1 character.
Hydradread -> NASCAR race car. Essentially the G1 character
Aquablast -> Porsche Le Mans. Essentially the G1 character
Drench -> Sports Coupe. Essentially the G1 character.
