@Ace Here's a pair of twins; I hope they aren't too powerful. Are double pretenders allowed?
Height: ~16 ft.
This. but, y'know, transformer-y (I've been on a bit of a Halo kick recently, okay?)
The Sparrowhawk, but with the robot mode's colors.
Weapons 'n such: In robot mode, Screwball's right forearm can transform into a Photon Burst Rifle (it's basically the TF version of Halo's Battle Rifle), and she carries a combat knife. In vehicle mode, she carries two chainguns and a missile launcher.
Height: ~16 ft.
Role: field medic
This. But, again, transformer-y
This, but with the robot mode colors
Weapons 'n such: being a medic, Screwup carries a wide variety of equipment to ensure that his fellow Autobots' sparks keep burning. The first of these is the Energon Repair Ray, which can repair most injuries on a single target and mildly irritate hostiles in a pinch. He also carries a supply of Energon grenades, which spread the same effects over a wide area. His hands can also transform into any number of repair tools for more delicate procedures. Like his twin sister, he carries a Photon Burst Rifle and a combat knife, and his vehicle mode has a small, automated gun turret.
Screwup and Screwball also possess a goliath double-pretender shell that they employ when a situation requires a metric frak-ton of firepower. The shell is operated by both twins working in unison, unable to function with only one occupant. The two constantly bicker over a name for the shell: while Screwup suggests calling it the Screwdriver, Scewball however insists that's "beyond-stupid-the-thing-doesn't-need-a-name-you-moron".
The shell is equipped with a machine gun turret over the left shoulder and a missile pod on the right. The right forearm can transform into either a Riot Cannon, another machine gun, or Screwup's repair ray, and the left can transform into a grenade launcher which can dispense either frag grenades or Screwup's Energon grenades. For melee combat, the shell is equipped with an energy sword in the right forearm and a shield on the left. The shell may be a powerhouse, but it is not invincible. It requires both twins to operate, as said above, and leaves much to be desired in the areas of speed and agility.
Personality wise, I'm not sure how to describe these two. I suck at writing character bios. I want to say they're kinda a hodge-podge of my characters from Cybertron Reborn, possessing Razorwing's genre-savviness, Doohickey's extroverted/dorkish nature (and combat armor), Thingamabob's cheerful outlook, and Bootleg's love for slang, obscenities, and firepower.
