This is how Intro: Optimus' narration goes in My Little Pony Transformers.
[We see Cybertron as we hear Optimus Prime's voice in the background]
Optimus Prime: (narrating) Before time began, there was the Cube. We no not where it comes from, only that it holds the power to create worlds, and fill them with life.
[We see that 'Cybertron' is really the Allspark]
Optimus Prime: (narrating) That is how our race was born. For a time, we lived in harmony. Some wanted it for good - others for evil. And so began the war. A war that ravaged our planet until it was consumer by death. And the cube lost to far reaches of space.
[The Allspark hits a couple of asteroids, the second one breaking on impact]
Optimus Prime: (narrating) We scattered across the galaxy, hoping to find it and rebuild our home. Searching every star... every world.
[We see the Allspark get pulled into Equestria's gravitational field]
Optimus Prime: (narrating) And just when all hope seemed lost, message of a new discovery. To us an unknown planet called... Equestria.
[We see Equestria]
[My Little Pony Transformers appears on the screen]
Optimus Prime: (narrating) But we were already too late.
[Screen fades to black]
