Author's Note: I had a lot of fan character requests this time! Oh, and to give you a good picture of what the Blue Comet observatory looks like then try imagining Sonic and the others living on Rosalina's ship in Super Mario Galaxy (anyone ever played that game?). Enjoy!

Special Guest: Nick, Joe, Kevin, Blaze

One morning (don't ask I just want to make time easy on me) on the Blue Comet observatory, Midnight walked on the bridge. They had come to a very plain area in space but it still had it's interests. Orange stars and constellations covered the dark blue sky. Midnight walked over to the Star Seek dome and stepped inside.

Sonic, Tails, Knuckles, and Cindy were observing the sky through their telescope.

"What's up?" Midnight asked.

"We've spotted a galaxy." Tails answered.

"And it looks like Nazo's left a few of his thugs behind." Knuckles added.

"Well then, let's show em' who's boss!" Cindy shouted.

"Chao!" Lil' Red shouted.

"Let's rally the others and clean up Nazo's mess." Sonic said as he walked outside.

"Could your speeches be any more cheesier?" A voice asked as Sonic walked out of the Star Seek dome. Sonic looked up to see Blaze lying on the roof of the observatory smirking down at him. Silver walked over.

"I'll bet you couldn't even say the word I!" Sonic snapped.

"Get him down from their." Sonic ordered as he began walking away. Silver used his telekinetic powers to throw Blaze back down onto the bridge. Blaze rubbed his head in pain.

"Now that was cold, Silver." Blaze groaned as he rubbed his head.

"You say I'm cold." Silver snapped as he folded his arms.

"What's the difference between you and me?" Blaze asked.

"I'm not a jerk." Silver answered coolly as he walked away. Midnight walked over to Blaze and healed his wounds with a beam of light.

"Now, what's his problem?" Blaze asked.

"He's just sad." Midnight answered.

"Why?" Blaze asked.

"Girlfriend trouble." Midnight whispered. Blaze and Midnight snickered.

Later on Tails pushed a button on his computer and created a bubble that suck Sonic and the others inside.

"Emerald, Frostbite, Sean, KC, Krystal, and I'll stay here and keep in contact just in case something happens." Tails explained through Sonic's communicator.

"Sure thing." Sonic said.

"I'm transporting you to the galaxy." Tails explained.

"Right. Hang on everyone!" Sonic shouted. They suddenly began plummeting through a tunnel of mixed colors.

Sonic was first to land on a patch of grass on a small planet in the galaxy. Knuckles, Espio, Silver, Shadow, Blaze, Cindy, Suicune, Shayla, Nick, Joe, Kevin, and Midnight suddenly fell on top of him.

"GET OFF!" Sonic wheezed. Everyone jumped off as quick as a wink.

"Thank you." Sonic sighed. Sonic flipped open his communicator.

"What's the mission Tails?" Sonic asked.

"There's some sort of energy spike here in the galaxy, it's on one of the planets. You need to search the planets to find out what's causing it." Tails answered.

"Alright. Knuckles, Espio, Blaze, you go to the planet ahead." Sonic ordered. Blaze gave a sarcastic laugh.

"Nick, Joe, Kevin, you go to the planet ahead of theirs." Sonic ordered. Nick, Joe, and Kevin nodded.

"Cindy, Suicune, Shayla, you stay here and inspect this planet." Sonic ordered.

"Alright." Shayla said.

"Shadow, Silver, Midnight, you come with me, I'll need your help on this trip." Sonic explained. Shadow, Silver, and Midnight nodded.

"Alright, let's go!" Nick shouted.

"Tails, can you activate the soar ability?" Sonic asked.

"Sure." Tails answered. Sonic, Shadow, Silver, Midnight, Nick, Kevin, Joe, Knuckles, Espio, and Blaze began hovering in the air. Sonic began flying to the farthest planet with Midnight, Shadow, and Silver flying closely behind. Nick, Kevin, and Joe flew to their planet as Knuckles, Espio, and Blaze began flying to theirs.

"Well, let's see what we can find." Suicune sighed as she began walking around.

Meanwhile Knuckles, Espio, and Blaze were having quite a feud.

"Since when was this your time to shine?!" Knuckles asked.

"Since I decided I was the most valuable team member." Blaze answered. Knuckles pounded his head in anger.

Meanwhile over at the farthest planet, Sonic, Shadow, Silver, and Midnight had just landed.

"The energy spike is really strong here. We must be close." Sonic explained. Just then a large black creature that looked like somewhat like a T-Rex appeared and began snapping at them.

"Just what we needed!" Sonic shouted as he jumped out of the way of the snapping jaws. Midnight casted a sphere of light in her hand and threw it at the T-Rex. It smacked it clear in the face and sent it flying on it's back.

"Nice job Midnight." Silver complemented as Sonic walked over to the fallen T-Rex. It suddenly sprang to life and swallowed Sonic whole.

"Sonic!" Midnight, Shadow, and Silver shouted in unison.

"Ah, sick man! His stomach's full of black tar stuff!" Sonic shouted.

"Hang on Sonic!" Silver shouted as he jumped up and used his telekinetic powers to throw four rocks at the T-Rex. The T-Rex ate the rocks whole as they shot at him.

"I thought you wanted to help me, not make me more cramped than I already am!" Sonic shouted from inside the T-Rex's body.

"Chaos Spear!" Shadow shouted as he shot ten bolts of lightning at the T-Rex. The spears stuck out of the T-Rex's head. The spears suddenly melted into the T-Rex's head. The T- Rex was apparently made of a tar like substance.

"I don't get it! How can we beat him?!" Silver asked. The T-Rex suddenly swung it's tail around and sent Midnight flying into a block of ice. Tiny jewels and coins fell out of the ice. Midnight shook off the pain and looked at the back of the T-Rex. A large aqua sphere glowed on the back.

"Wait a minute." Midnight whispered. She shot a spear of light out at the sphere. The T-Rex roared in pain and turned to Midnight. As it took a snap at her, Midnight moved out of the way and formed a string of light. She tied it around the T-Rex's legs and tripped it. It collapsed on the ground. Midnight ran over to the tail of the T-Rex and grabbed it.

"Shadow, Silver, come help me!" Midnight shouted. Shadow and Silver ran over to Midnight and grabbed the tail.

"Pull!" Midnight shouted. They pulled with all their might until they couldn't pull anymore.

"When I count to three we'll let go of the tail! One, two, three!" Midnight shouted. They released their grip from the tail and sent it flying right into the glowing sphere. The T-Rex roared loudly and fell to the ground. It suddenly melted and a puddle of black tar formed.

"Yuck." Midnight said. A large lump suddenly appeared in the tar. Bits of the tar dripped off of the lump to reveal Sonic who was practically swimming in it.

"Oh, oh, this is just great! This is just perfect!" Sonic raged as he tried to shake some of the tar off of himself.

"What's that red glow next to you?" Silver asked.

"What?" Sonic asked as he turned to a glowing bump beside him.

"Is that what I think it is?" Midnight asked as she walked over to Sonic and reached in the tar. She pulled out a tar covered Chaos Emerald. They all gasped. The Chaos Emerald glowed brightly.

"Hang on I think there's something else." Midnight explained. She pulled out a small blue disc. A hologram of Nazo suddenly appeared.

"I see you've met one of my friends. Though you have other matters to attend to. As we speak a black hole is forming beneath the planet of your loved ones. I'd rush over there if I were you." Nazo explained.

"What?" Sonic asked. He turned to the first planet where Suicune, Shayla, and Cindy were walking around. Sonic gasped. A black hole suddenly appeared and began sucking in parts of the planet.

"Suicune, Shayla, Cindy! We've got to get over there now!" Sonic shouted. He jumped up and began to soar over to the planet Nick, Kevin, and Joe were searching. Sonic, Shadow, Silver and Midnight landed quickly and safely.

"We have to hurry. We found the energy spike but Suicune, Shayla, and Cindy are in danger! Let's go!" Sonic shouted. Nick, Kevin, and Joe nodded and followed Sonic to the planet Knuckles, Espio, and Blaze were inspected.

"Knuckles, Espio, Blaze! The girls are in trouble! We have to hurry!" Sonic shouted.

"C'mon!" Knuckles shouted as he jumped up and began following Sonic. Espio and Blaze followed. Suicune, Shayla, and Cindy were griping a tree as some of the objects of the planet began flying into the black hole.

"Hang on!" Cindy shouted. The black hole suddenly pulled Suicune off of the tree. Suicune screamed as she began to fly into the black hole. Just then Espio grabbed Suicune and carried her back over to the tree.

"Espio!" Suicune shouted.

"Are you alright?" Espio asked. Sonic and the others flew over to the tree.

"Let's get out of here!" Midnight shouted.

"I'm with you all the way!" Blaze agreed. Sonic and the others jumped off of the tree and began soaring back to the Blue Comet. They landed gently on the landing zone and sighed with relief.

"So who had fun?" Silver asked.

"I hate you Silver." Sonic panted.

I played Mario Galaxy and I loved it! Most of the adventure will be based off of Mario Galaxy. I thought the crossover would be awesome so I didn't hesitate. See ya later!
