You’re the wife of Optimus Prime and you’re also another Prime yourself. You, along with Prime, Ratchet, Bumble Bee, Ironhide, and a few other Autobots have allied with a U.S military task force called NEST and you guys stop Decepticon activity.

When Sam Witwicky was being held hostage by Megatron in Philadelphia, Optimus went and saved which turned out to be a little battle between the two. Optimus ended up being stabbed and shot through the chest by Megatron. The U.S military brought his body back to the NEST base and you and the other Autobots immediately came to the base.

You all drove up in your vehicle modes and you guys were greeted by Theodore Galloway, a U.S government official, who evidently did not like Autobots. Lennox was telling his men to stand down since they were all pointing their weapons at you and the other Autobots under Galloway’s orders
