Enter Shadow (Part 2)

New Townsville: Science lab

Everyone were minding their own businesses when, an alarm rang.

Ken pressed a button, and a screen revealed Shadow, Rouge, and Bubbles fighting Chaos 2.

"It's Bubbles! She's fighting Chaos with a black hedgehog and a bat." Poochi said.

"That's Shadow and Rouge." Sonic said. "Come on! Let's go help them!"

Everyone rushed out of the lab, and to the warehouse.

New Townsville: Abandoned warehouse

Chaos 2 continued to pummel Shadow, Rouge, and Bubbles.

"He's strong. I can't let him have these Emeralds, I'll have to tap into the Emeralds' power." Shadow said, and a red and green glow surrounded him.

Shadow then rushed at Chaos 2 and attacked him with Chaos Spear, knocking him back a few feet.

"Chaos Nightmare!" Purple orbs formed around Shadow's fists and he punched Chaos 2.

"Sticky Bubbles!" Bubbles sent several sticky bubbles at Chaos 2, pinning him to the ground.

"Chaos Boost!" Shadow is about to ram into Chaos 2, but he teleports behind Shadow and punch him.

Rouge tries to Screw Kick Chaos 2, but he forms an electric shield to block it, and sent a water blast at her.

"Bursting Bubbles!" Bubbles blew a large bubble at Chaos 2, but he catch it and pop it by squeezing it.

"That's so cruel!" Bubbles said.

Chaos 2 extended his arm and punched Bubbles, knocking her out.

"Chaos Spear!" Shadow shot arrows made of Chaos energy at Chaos 2, but he teleports and knock down Shadow from behind.

Shadow was sent crashing into a wall, the red and green aura surrounding him disappeared, and he was no longer powered by the Emeralds.

"Darn it! It can't end just yet!" Shadow said as he got up.

Chaos 2 comes by and knocks him toward the entrance.

Chaos 2 was about to take Shadow's Emeralds, when the door flew open and came bursting in was Sonic, who headbutted Chaos 2 into a crate.

"Shadow? What're you doing here?" Sonic asked.

"Trying to give you these, but someone else wants them." Shadow replied as he showed Sonic his Chaos Emeralds.

"Bubbles! Are you okay?" Blossom and Buttercup asked as Bubbles got up.

"Yeah, now that you guys are here." Bubbles replied.

"Let's get this guy!" Sonic said as he and Shadow energized themselves with the Chaos Emeralds.

Sonic and Shadow both used Homing Attack on Chaos 2, knocking him back a few feet.

Sonic charged up a Light Speed Attack, and unleashed it on Chaos 2, and Shadow followed with Chaos Burst.

Chaos 2 wasn't fazed from the attack and started drawing more power from the Emeralds, and whacked Sonic and Shadow back.

Chaos 2's attack cancelled the power boost of the Chaos Emeralds on Sonic and Shadow.

"Here! Why don't you try using them?" Shadow said as he threw the Red and Green Emeralds to Blossom and Buttercup, and Chaos 2 turned his gaze towards them.

"How does this work? I don't really know how Bubbles did it, but I'll still have to try." Blossom thought, and she held the Red Emerald in her hand and concentrated, suddenly the Emerald transferred its power to her, and she gave off a red and white aura.

Buttercup tried the same thing, and soon she was giving off a green and white aura.

Chaos 2 extended his lower arms at Blossom and Buttercup, but the two dodged.

Blossom suddenly used ice breath on Chaos 2's arms, freezing them in place.

Buttercup threw a fireball at Chaos 2's frozen arms, smashing them.

"Fro-Yo Attack!" Blossom shoots her yo-yo at Chaos 2, which freeze him solid.

"Fireball Slam!" Buttercup hammered a fireball at Chaos 2, smashing him to pieces.

"That was awesome!" Sonic said.

"You really showed him." Rouge said.

"Let's get the Emeralds back to the lab." Blossom said, but then, there was a "Crash!" and Eggman came bursting through the wall.

"Ah, so there are the Chaos Emeralds, we'll be taking them, thank you." Eggman said and mechanical hands snatched the Chaos Emeralds in the heroes' possession.

"Hey! Give them back!" Buttercup demanded.

"Demanding will get you nowhere, but I'll give you this." Eggman said as he tossed a cube to the ground, and a giant robot started to form from it.

Chaos 2 beats Bubbles, Shadow, and Rouge, and he's about to take the Emeralds, Sonic comes to lend Shadow a hand. But however, they're still no match for Chaos 2. Fortunately, Blossom and Buttercup draw power from the Emeralds and with it, they defeat Chaos 2. Then, Eggman comes by and steals the Emeralds and leave a giant robot behind. To be continued...
