The heroes head outside Twilight's Libary, Rainbow Dash thankfully is in her pony form. The two heroes look around, and see many black Alicorns, but these alicorns are small, and look like bugs. "Ugh, what are those?" Sonic asks. "Changealings! They can mimic any pony, or this case, person!" RD exclaims. Suddenly, the heroes get surrounded by clone Sonics. "Hmph, this I'll be fun." Sonic smirks. Sonic homing attacks some of the Changealings, and they try to copy Sonic, but they're not as fast. "Aw, come on! Where's the challenge?!" Sonic asks cockly. Another Changealing tries to sideswipe Sonic, but Rainbow Dash kicks it away from Sonic. "Thanks Dash." Sonic thanks Rainbow Dash. "No prob Sonic." RD smiles. But the battle ain't over yet. Coming from the entrace of Ponyville are some of 's mechs. Buzz Bombers, Egg Pawns, hell even Bombs, the annoying enemy from Sonic 1.

"Eggman's mechs?! What are they doing here?" Sonic thinks as the robots charge through Ponyville. A Egg Pawn shoots Sonic from behind, but Rainbow Dash warns Sonic. "SONIC! BEHIND YOU!" RD yells. Sonic turns around, and sees the laser blast from the Egg Pawn's gun, and somersaults to get out of the way of the blast. Sonic meets up with Rainbow Dash, only to be surrounded by Egg Pawns and Changealings. "Ya thinking what I'm thinking?" Sonic asks, smiling. "Lets finish this." RD smirks. The two speedsters spin in a circle in the same direction. The result is a giant tornado, that sucks up the rest of the robots and Changealings, and flings them out of Ponyville. As the tornado dies down, the two speedsters stop running, and get ready for more enemies. "That attack could only be done by two villans.." Sonic says. Suddenly, from the sky, there's evil laughter. "That you're right, my spikey blue friend!" A man's voice exclaims at our heroes. Suddenly from the sky, Eggman comes in his Egg Mobile, and the queen of the Changealings, Queen Chrysalis is next to him. "Hmph, as persistant as ever I see." Chrysalis smiles evilly. Sonic and Rainbow Dash go into battle stance.

"You won't give up, will you, Egghead?" Sonic jokes. Eggman just gets annoyed by that comment. "MY NAME IS EGGMAN! You know that, and make fun of me!" Eggman yells. Sonic touches his nose with is finger. "What ever, Egghead." RD smirks. The two heroes charge at Eggman and Chrysalis, but get blasted by a spell Chrysalis uses, and slam into a wall. The wall collapses on our heroes. "Hope you like your new forms, heroes! HA,HA,HA,HA,HA!" Eggman laughs. The two villans leave Ponyville, with Sonic and Rainbow Dash stuck under piles of bricks.
