I am Optimus Prime:

With the Decepticons finally vanquished, we can at last find peace and perhaps rebuild some of what we have lost. We have friends here on Earth, and as we help rebuild what the Decepticons tried to destroy, we hope to earn more friends among you and be able to live in peace among the indigenous inhabitants of your world. As more Autobots find their way to Earth, please do not be afraid. We have no intention of harming you or your world, we only seek refuge from forced isolation in the vast emptiness of space, scattered among the stars. With our home lost to us, we have no where else to go. Please accept our friendship and protection, as it is in our nature to protect and to learn. Before the war that tore our world apart had begun, we were a peaceful race, dedicated to science, research, and learning. We wish only to return to that way of life, to protect our friends here, and hopefully be permitted to call Earth our home as well...

Until the day, til all are one.
Optimus Prime
