They came down from the stars in boats made of iron and steel. They descended onto the planet and freed it from the greed and tyranny of its reagent.

The ponies called them heroes. They call themselves Decepticons.

But whatever they are, they've done their best to improve life for the people of Equestria. To bring them out of poverty and slavery, to bring them out of fear and despair. When Queen Celestia returns, she can't abide, so she decides it's time to remind the ponies of the status quo ... whatever it takes, even if it means terminating the Decepticon leader.

Note: Takes places in the Transformers "Shattered Glass" universe.
