This is how Meeting the Autobots goes in More Than Meets The Eye Part 1.
Narrator: Many millions of years ago, on the planet Cybertron, life existed. But, not life as we know it today. Intelligent robots, that could think and feel inhabited the cities. They were called Autobots and Decepticons. But, the brutal Decepticons were driven by a single goal, total domination. They set out to destroy the peace-loving Autobots, and a war between the forces of good and evil raged across Cybertron. Devastating all in its path. Draining the planet's once rich sources of energy. The Autobots, on the verge of extinction, battle valiantly to survive.
[Twilight goes over to Wheeljack]
Twilight Sparkle: Why's Cybertron in danger?
Wheeljack: The planet is dying.
[On the way to Iacon, they run into Starscream, Thundercracker, Skywarp, Sunstorm, Hotlink, Bitstream, Nacelle, and other seekers]
Wheeljack: Uh-oh. Decepticons.
[They see them coming]
Starscream: Autobots! Stop them!
[Thundercracker, Skywarp, Sunstorm, Hotlink, Bitstream, Nacelle, and the other seekers start shooting at Wheeljack]
[Sunstorm and Bitstream spot the Mane Six, Starlight, Trixie, Thorax, and Discord]
Sunstorm: Starscream, they have passengers with them.
Bitstream: Eight of them are ponies, one's a Changeling, and one's a Draconequus.
[Starscream looks at them]
Starscream: Hmm. They could be of use.
