The long-awaited sequel of Sonic: Rescue at Midnight Castle is right here! Previously, Sonic traveled to the equine world to help a group of ponies and a human stop the sinister Tirek. Now It's Firefly and Megan's turn to travel to Sonic's world and help the Sonic Team save it from being destroyed. Can they do it? Will they be stopped by Shadow and Dr. Eggman? Read on to find out. Oh, also, I'm putting on hold my Hearth's Warming Eve crossover for a while because I was stupid enough not to finish it in time for the Fan-fiction contest.

Prologue: Shadow Reborn

"Intruder alert! Intruder alert! Security Breach at Gate 3! Intruder has been located in the North Quadrant and is moving in the direction of the underground base! All units prepare to engage! Emergency battle formations! Standard battle procedures initiated! Locate and stop the intruder from entering the security area! This is not a drill! Repeat, this is not a drill!"

A secret military base was being infiltrated by the notorious Dr. Eggman. He is a mad scientist sporting an I.Q. of over 300 who makes robot armies to try and take over the world.

"Hahahahahaha! That was all too easy!" he said. "Let's take a look what my grandfather was working on... a top secret military weapon! The military shut down the research because they feared it!"

He fought his way past security robots and the like, which wasn't that hard to do. He made it to the door of where the military weapon was, and when the doors opened, by way of hacking the code, he went up to the control center of the weapon.

"Oh ho!" he stated. "So this is the military's top secret weapon? It'a a lot smaller than I expected! Enter user data... aha... enter password... Password is Ma-ri-a. Maria. Now all I have to do is place the Chaos Emerald into this console."

He placed the emerald into the console, and jumped down to the chamber with his mech. The chamber rose up in front of him, and opened up, revealing a black hedgehog with red stripes on his quills.

"What's that? Is that you, Sonic? Are you trying to spoil my plans again?" Eggman demanded. But he took another look at the hedgehog and found that it wasn't Sonic. "Wait a minute. You're not Sonic! This is impossible!"

"My name is Shadow." the hedgehog introduced. "Since you were so kind to release me, my master... I will grant you one wish."

An alarm sounded and Eggman was caught off guard. "Now what?!"

"Behold the true power I possess!" Shadow stated as he took on the enemy mech. It only took a few homing attacks to take it down.

"Destroying that guard robot was spectacular!" Eggman exclaimed, surprised at what he saw out of the hedgehog. "So Shadow, YOU are the military's top secret weapon? But what did you mean when you said you will grant me a wish?"

"Bring more Chaos Emeralds." Shadow stated.

"Shadow, wait!"

"I'll be waiting for you in the central control room on the Space Colony ARK." With that, Shadow turned and left.

"ARK?" Eggman asked. He didn't know what Shadow was talking about, but he was going to find out what it was soon enough.

And that's Chapter 1. Stay tuned for Chapter 2 as Sonic tries to run away from the military, also including Firefly and Megan's arrival.
