I was thinking 6 transformers...more unknown G1 types.
A-Gears(Old Toyota Truck/Scion xP)
A-Windcharger(Dodge Charger Police Car)
A-Cosmos (UFO)/Chevy Volt)
A/D-Skyfire (F-35 Lightning II) He will be called Jetfire later down the line.
D-Nightflight (F-117 Nighthawk "Stealth Fighter")
D-Swindle (Jeep Wrangler)
D-Axer (BMW revised the R1100RT-P)
D-Detour (Ford Fusion)
I think it will be Knightriderish for the most part...but Premiers, Finales and Sweeps alot of action and appearences by Know Transformers.
