Optimus Prime (BAY)

You were still very small when your father helped the Autobots end the war with the Decepticons and the SLT (Slayer Liquidation of Transformers, otherwise known as the Funeral Wind). Optimus vaguely remembers you, just as you remember him, but he remembered your gaze and facial features. (You had heterochromia: your left eye was blue, and your right eye was red). As it happened, by the time you grew up, your parents had passed away, and from your father remained a great artifact—the Matrix of the Chosen, which chose you, and you accepted the title of the Chosen One (You were 15 years old at the time). After a long time, you lived in your underground laboratory and headquarters simultaneously, which was located beneath the earth. Suddenly, you heard sounds from outside. Stepping outside, you discovered that Optimus was wounded and lying unconscious by the ruins of your home.
