"Surprised, my little pony? I present you and your princess friend Badnik Model RD-1010, or 'Metal Dash', if you like. My demand is simple, surrender this country or my minion will lay waste to this settlement!"

A unpleasant surprise in Appleloosa! The infamous Doctor Ivo 'Eggman' Robotnik has entered Equestria….and not turned into a pony.

Twilight, confused by Eggman remaining human and not turning into 'Eggmane'; Rainbow Dash, shocked that a imposter will be used to destroy and hurt innocents should Twilight refuse the surrender.
