Robotnik: What was it you wanted, Snively?
Snively: Well, sir, it’s just…
Robotnik: … just what, Snively?
Snively: It’s really not that big a deal, sir-
*squeal* W-well, s-sir, it’s t-the…
Robotnik: I’m growing impatient Snively. WHAT IS IT!?
Snively: Sir, the hedgehog has been spotted in the Eastern Hemisphere!
Snively cowers before Robotnik, but looks up to find an expression of shock on Eggman’s face.
Robotnik: W-what, did you say, Snively?
Snively: It’s true, sir! The hedgehog was spotted by the Egg Fleet in the Eastern Hemisphere! And he’s not alone! The hedgehog was reported among two other hedgehogs, one of them being Shadow!
Robotnik: (So that’s where he wound up after I ejected him from the Space Colony.)
Robotnik reminisces about the way he had ejected Shadow from the Space Colony ARK moments before it’s impact with Ponyville months ago. The Colony had been used to attack Asura before Eggman’s decent into madness, only to be tossed through to portal leading into Equestria days later and crashing into Ponyville during Eggman’s imprisonment at the hands of Snively. It was soon after revealed that Ponyville had been protected by a shield generated by Lyra, and was completely undamaged. Eggman couldn’t say the same for the ARK, which was completely obliterated by the impact.
Robotnik: Snively, I’m leaving now, and I want you to take care of things while I’m away. I’ll also be taking my Final Fortress with me, along with an entire legion of my finest troops. You can monitor the Empire’s progress through your new living quarters in Eggmanland, and you may use my new control room. But Snively, if I see so much as one molecule of machinery out of place when I get back, well… I’ll turn you into the paperweight I’ve always wanted. Understood?
Snively: Y-y-yes, s-sir…
And with that, Robotnik leaves to confront that hedgehog…
Sonic, the Hedgehog.
