Metal Gear has fallen into the hooves of an Equestrian revolutionary, who, with the backing of his human mercenary allies, intends to use it to depose Celestia and crown himself ruler. Having crossed into Equestria in pursuit of this rogue weapon, the legendary Solid Snake must ally with the residents of Ponyville to prevent a nuclear catastrophe.

See also Equestria Gear Solid, the hilarious spin-off EQG parody in which everything you know is wrong, and every single character from the story is an awful caricature of themselves.

Cloudsdale. Bastion of the Pegasi, linchpin of weather control, home to the Wonderbolts. A magnificent metropolis gracing the skies of Equestria. So what happens when an oblivious human starts stumbling around in a sailplane? As they say, hilarity ensues.

This story is a sequel to The Dresden Fillies: False Masks

It's been a while since the girls have seen their good friend Harry Dresden. Discord escaped, Luna attended her first Nightmare Night, the Royal Wedding was crashed by hordes of changelings, and Pinkie Pie threw a statistically improbable number of parties. They tried inviting Dresden, but between his new job and new apprentice, he always claimed to be too busy. The solution was obvious; if he couldn't come to his friends, they needed to go visit him. Besides, they say Earth is lovely this time of year. What could go wrong?

The Princesses find an alien creature barely clinging to life at the scene of a terrifying crash. Can the Combined Power of the Elements of Harmony save it, or more importantly, should they save it? Will the arrival of this strange creature tear Equestria apart?
