Some sort of Van.
A whip/lasso, also his Targetmaster.
Mercuryfist is his Targetmaster, and its female. She transforms into his pistol.
Color Scheme: Edit
Mostly red, with some white.
U-Turn actually encountered Thomastrain before, and was nicknamed "The last Autobot" although he actually really wasn't. Even though Loco didn't know that they had more, U-Turn still kept the alias anyways.
U-Turn stayed around Brightlight after Optimus left.
