Name: Chassis, Wheelie, and XTC 
Gender: Female
Height: 7 ft. 
Alliance: Autobot 

Disguise Type: Honda Racing Motorcycles. The Motorcycle form factor allows these three autobots to go where most other transformers cannot go. In robotic form they aren't any larger than regular humans and can go inside buildings, use elevators, and most importantly use cover that would be impossible for other transformers to hide behind. Chassis has yellow racing stripes, Wheelie uses blue while XTC uses red.

Appearance: In humanoid form the three sisters ride on their combined wheels as if upon a unicycle. They can, however walk on their legs when necessary but rarely do so except when skulking about, trying not to be seen. They also have the capacity to merge, the three of them coming together into one form that is the size of a typical sized transformer like Bumblebee, Sideswipe or other automobiles. 

Holographic Human: Chassis, Wheelie and XTC use quite generic close helmeted female riders. 

Weapons:
--Chassis: Chassis is their heavy hitter, wielding an assault rifle and an underslung grenade launcher. She alone has a sidecar. The sidecar contains a cluster of rockets. Typically these are expended in the opening salvo and transforms back into Chassis' structure
--Wheelie: Prefers the use of her submachine gun and her chain sword. The chain sword can perform much like a sword but can also loosen into the whip version. This can be quite deadly when the other end is held by one of her sisters for clothesline and tripping attacks.
--XTC: Prefers the use of a six foot long 25mm anti-material rifle. This thing packs a hell of a punch and has a backup SMG for when things go south.

Personality: Chassis is the most emotionally stable of the three. She's the rational, reasonable one. Wheelie is a firebrand, an adrenalin junkie who enjoys mixing it up with the opponents three times her size. XTC, however, is laid back, slothful and seductive, and quite enjoys being the one sitting in the back peering through a sniper scope.

Background: Chassis, Wheelie and XTC were once a single transformer. Captured by Shockwave while on recon she was experimented on with Dark Energon and when nothing resulted she was cut asunder and thrown onto a conveyer leading down to the smelting pits for reconstitution. Surprisingly, the severed parts, still infused with dark energon reconstituted themselves into three identical beings. Her very spark became three. Oddly, the three had very different possibilities as well.

Other: The sisterhood has a special rapport, a spark bond, that allows them to communicate via some form of quantum entanglement.
