After Planet Aether has been brought to peace and stabilized, Samus Aran doesn't get much rest when she's sent to reconnoiter a nameless planet on the edge of Galactic Federation space. Ostensibly, she was supposed to determine the size of a Space Pirate operation that was mining Phazon on this planet... and mark the place for a quick strike by Federation forces if it came down to it.

But when things become much more complicated beyond what her mission brief had stated, she may find that her fate and those of some unlikely allies may be intertwined. The battle that rages on the ground in a fight for survival and duty may have Samus questioning herself when a new front in an undeclared, nameless war is opened... in her mind.

Based on the movie: Sonic the Hedgehog, but with some changes.

After fleeing to planet Earth, Sonic the Hedgehog has been secretly living in Canterlot City as his new home for the past decade along with his incredible power of super speed. Things went well for him, until he accidentally knocks out the power grid, getting the attention of the military organization, G.U.N., along with the evil genius, Dr. Robotnik.

Meanwhile, the Equestria Girls was preparing for their upcoming graduation, leaving Sunset Shimmer unsure of her future. When the power grid near their school was knocked down, CHS was in suspicion by G.U.N., sending in a special agent to investigate as a result.

When the two groups meet up due to circumstances, Sonic and The Equestria Girls must team up to retrieve Sonic's rings and stop Robotnik from using Sonic's power for world domination while fleeing from the government.
