This story is a sequel to The Elements of Harmony and the Savior of Worlds

The Conversion Bureaus have won. Humanity has been ponified, all traces of our civilization wiped clean from an Earth turned into Equestria. Princess Celestia rules over all, the tyranny of free thought abolished.

Humanity is at the cusp of a golden age. With allies both near and far, biped and quadruped, we strive for greatness, united as never before. Our mark shall be made in space, our influence felt throughout this Spiral Arm.

The Tyrant Princess sees this and is angered. A dome is opened... but this time, humanity is not alone against the Conversion Bureaus.

A spinoff/sequel to The Elements of Harmony and the Savior of Worlds, taking a place about a year after the events there, and my own little 'take' on the Conversion Bureau. This makes it a crossover with Transformers Generation One, GI Joe A Real American Hero and My Little Pony G1.

Thanks to Velkaden for the title. As well as Shubzilla for proofreading, the anti-Conversion Bureau for their help and SJC for help with the look of Megan.

A few weeks ago, Chrysalis and her brood attacked Ponyville for revenge against Twilight. During the fight, the final spells of the two collide and create a portal that they're sucked into. The Princesses with the help of the others manage to summon them back only to find... that the two are marefriends!? How the buck did that happen!?

During the battle with the changelings, a trapped Discord manages an undirected spell that reaches across universes to bring an agent of chaos to Equestria. What's brought back more than qualifies.

Steam! Gears! SCIENCE! A very confused Spark! And, eventually, really good coffee.

Here comes Agatha Heterodyne--MARE GENIUS!
