Oblivion? sounds like Fallout: New Vegas, actually, cuz Rex and Boone are also in that game, and Boone is an ex-NCR Ranger.
I've got 2 characters who're Transformers. one's a Decepticon traitor (like Jetfire from Revenge of the Fallen) and is a Piaggio FLY 150. his name is Dart. the scooter he transforms into is black with yellow stripes, and when in scooter-form, his wheels are from the Piaggio MP3 300. he also has a chrome Ferrari "Prancing Horse" badge on his front fender, facing up and out. despite his small size, he's equipped with shoulder-mounted rocket-launchers and what appears to be a Beam Rifle from Halo 3.
the other is a new recruit to the Autobots. He's a 2012 Rolls-Royce Phantom Coupe. despite the fact he's a luxury car on the outside, on the inside, he's more bloodthirsty than the late Ironhide. and yet, despite this bloodthirtiness, he's stealthier than any other. aptly going my the moniker, Ninja, he's one of the meanest, quickest, and most cunning Transformers the world has ever seen. thank god he's a good guy.
