TFW2005 member Red Leader has revealed the bios for the TFA Target exclusive sets of Sunstorm vs. Ratchet and (purple/G1 colors) Shockwave vs. Bumblebee.

Sunstorm vs. Ratchet:
Yet another clone of Starscream has appeared on Earth to threaten the Autobots. Sunstorm is a cackling madman determined to destroy everything in his path. He is also a living power battery, absorbing any energy directed at him from sunlight to high powered lasers. Only Autobot Ratchet has the scientific know how to develop a device capable of defeating such a powerful new enemy.

Ratchet Galactic Powers and Abilities
> Huge array of surgical and mechanical tools
> Once considered most talented medic on Cybertron
> Trained at Protihex Medical Mechanics University

Sunstorm Galactic Powers and Abilites
> Absorbs energy to use as powerful laserblasts
> Can generate blinding flashes of light
> Fastest clone of Starscream

Shockwave vs. Bumblebee:
Because of his job operating deep undercover in the Autobot ranks, Shockwave very rarely lets his emotions get the better of him. There's something about Bumblebee though that just bugs him. The hyperactive young Autobot annoys him enough to let his cover slip, converts into his Decepticon cannon mode and attacks!

Bumblebee Galactic Powers and Abilities
> Energy Stingers fire electrical pulses
> Rocket assisted jumps
> Totally Fearless

Shockwave Galactic Powers and Abilities
> Expert code breaker and thief
> Enjoys blackmailing Autobots in positions of power
> Stole his Autobot identity from old historical files

Notice that Sunstorm's bio, while sticking with him being a Starscream clone, lacks any mentioning of him being a sycophant like the clone from the show  that shares his color scheme.
