Chapter 5: The Possible Return of a Dark Nightmare

(At Sonic's house)

E-123 Omega was brought to the garage so Tails and Professor E. Gadd could work on the repairs.

Shadow- Will Omega be ok?

Tails- Well, he's in pretty bad shape, but I should be able to fix him. I can get him back online now, but I'm afraid we don't have time to fully repair him. You know with the whole mess we're currently in.

Sonic was standing right behind Shadow, taking a bite out of a chilidog.

Sonic- Don't worry, Shadow. (Munches on the chilidog) We'll take good care of Omega.

Shadow- Do you really have to talk with your mouth full?

Tails and Professor E. Gadd finished some of the repairs and E-123 Omega turned himself back on. Omega looked around and tried to move, but Omega stopped he noticed his body was still damaged.

Rouge- Omega, try not to move around too much.

E-123 Omega- Rouge the bat…danger! I must report danger!

Shadow- You mean Bowser? I already took care of him.

E-123 Omega- Error.

Mario- That huge dinosaur-like monster you met in the jungle.

E-123 Omega- Negative! Bowser not danger. Sensors indicated the Master Emerald was taken from Angel Island.

Knuckles- WHAT?! The Master Emerald has been stolen!

Luigi- Knuckles, I think we should let the robot finish.

E-123 Omega- I went searching for the Master Emerald since it is very important to our world. However, when I encountered the thief, he attacked me and damaged me. He moved too fast for the sensors to find him. But I estimate it was in the form of a hedgehog and the power felt similar to the disaster on Angel Island 8 years ago.

Suddenly, a look of horror appeared on Sonic and Shadow's face. Their expressions were like they just saw the devil. Mario looked at Sonic and Shadow and that almost made Mario nervous.

Mario- Uh…Sonic? Is everything alright?

Sonic pulled himself together, took another bit of his chilidog, and calmed himself down.

Sonic- I think I might know of a hedgehog that fits the description Omega just gave us…and let me tell you, I'm hoping I'm wrong…

Mario- Oh really? Do tell.

Sonic- Very well. As you know, the Chaos Emeralds hold a vast amount of Chaos Energy. However they hold both positive and negative energy. Depending on the purpose for the user depends on whether you get positive or negative energy. When Shadow, Silver, and I transform into our super forms is an example of when we absorb positive energy from the emeralds. But over the years, each time the Chaos Emeralds were used for negative purposes, a horrible monster was slowly forming inside the Chaos Emeralds. This monster's name was Nazo (Nazo is a character from the Newgrounds movie "Nazo Unleashed" and Chakra X has owner rights over him, not me). He looks like a hedgehog, but he was worse than any monster I've ever faced before. And believe me, he was worse than either Eggman or Bowser. Not as bad as Tabuu, but still on a high danger level. Even in our super forms, Nazo nearly killed us. And unlike Bowser or Eggman, Nazo is not interested in wealth or ruling. Nazo's only interest is watching the world burn. Luckily, Shadow and I developed a new power and used to kill Nazo. That happened 8 years ago. There's no way he's still alive or Nazo would've attacked again by now.

Mario- I can understand that a bit. I've been hoping Tabuu wouldn't come back after you and I dealt with him. But I've been getting signs that Tabuu is still alive and ready to strike at just about any moment.

Sonic- But Tabuu is a god. Nazo is mortal, like us.

Suddenly, an alarm went off on Professor E. Gadd's computer.

Professor E. Gadd- Looks like Omega's story will have to wait. I'm detecting Bowser's Koopalings are wreaking havoc all over the place. They've each built a castle around this jumbled world and are causing trouble.

Sonic- We don't have time for this!

Mario- I guess the best course of action is to split up into teams of two like we did earlier and each team will take out a Koopaling's castle.

(Eggman's lair)

Bowser and Eggman were looking at Eggman's computer.

Eggman- Clever idea, Bowser. We'll let your Koopalings help us find where Sonic and Mario are hiding out.

Bowser- Yes. Once they destroy all seven castles, we'll know right where their base of operation is. Then we'll kidnap Princess Peach.

Eggman- And when they come after us to rescue her, we'll show them our little surprise. Hehehe!
