Sonic Adventure: Across Time and Dimensions Part 1

"C'mon Tails, we gotta find Robotnik!" said Sonic.

"Right behind you" replied Tails. Sonic and Tails rush through Marble Zone, trying to find Robotnik, who has stolen the Chaos Emeralds.

"Sonic! Look out!" yelled Tails as a badnik rose up from the lava pool Sonic had prepared to jump over.

"No problem!" said Sonic as he spun straight through the enemy and landed on the other side of the pool.

"Piece of cake!" said Sonic. Suddenly, cannon fired, and before he knew it, Sonic was on the ground.

"Sonic, it's Robotnik!" yelled Tails as Sonic recovered.

"Ohohoho! What's the matter, Sonic? Not at the top of your game today? Pity, I'd love to stay and chat, but I have some very important business to take care of!" said Robotnik as he flew off in his Eggmobile.

"C'mon Tails, let's go after him! We can't let him get away with the Chaos Emeralds!" said Sonic as he blasted off after Robotnik. Soon they came upon a large egg-shaped building in the middle of a group of tall trees.

"Heh, y'know for someone with an IQ of 300, Robotnik sure is bad at finding good hiding places for his giant buildings of doom" joked Sonic. Sonic rushed around the building, looking for an entrance.

"Hm, no way in. Hey, Tails, you think you could find some way to get in this thing?" asked Sonic. Without a reply, Tails started walking around all the trees surrounding the building and knocking on them.

"Uh, Tails, buddy, you OK?" asked Sonic.

Tails replied with just a "Sh" Sonic just folded his arms and tapped his foot impatiently. Soon, Tails stopped by a tree.

"Sonic, this tree is hollow. It's probably a secret entrance. I just need to find the-here it is!" said Tails as he opened a panel camouflaged on the tree.

"Now just press this, plug this into here, and voila, it's open" said Tails as the side of the tree opened, revealing a tunnel leading down into the secret entrance.

"Great job little bro, now let's go kick some Ro-butt-nik!" said Sonic as he jumped down into the entrance with Tails following close behind. Sonic and Tails landed in a dark hallway.

"Well, only one way to go" said Sonic, "Let's go get the Chaos Emeralds back!" However, as Sonic prepares to start running, Tails rushes forward and grabs Sonics arm.

"Hold up, Sonic. Remember, this is Robotniks base, so it's probably filled with traps for intruders.

"Good point, we'll just have to rush through at supersonic speed!" replied Sonic. Sonic rushes forward and, just like Tails said, traps begin activating left and right. Spikes shoot out of the ground as Sonic rushes over spots with motion sensor activators, flames shoot out of the walls as Sonic runs through detector lasers, and lasers blast out of turrets on the ceiling as Sonic runs in sight. He jumps over the spikes, slides under the fire coming from the wall, and jumps in front of turrets as he quickly moves, making the turrets hit each other. The rest of the traps don't even have time to hit Sonic, though, because by the time he activates them he is already long gone. Tails does well with keeping up with Sonic as he flies over all the traps.

"Whew, these tunnels are a lot bigger than I thought" said Sonic.

"They are underground. The building Robotnik went in must be one entry point out of hundreds! Who knows how long these tunnels run through the ground, or here else they come out" replied Tails.

"Then let's find the center, that's gotta be where Robotnik is" said Sonic.

"But who knows where the center is exactly? I could try to use my hand-held, but I don't think it's a good idea to stop moving in these tunnels, they're way too dangerous" said Tails.

"I know! Fun, huh!" replied Sonic as he breaks the sound barrier running through the tunnels.

Meanwhile...

Robotnik places the Chaos Emeralds into seven pillars that surround a larger machine with a large ring on top.

"Sonic won't know what hit him after I activate this machine using the infinite power of the Chaos Emeralds. I hope you like surprises, hedgehog!" said Robotnik.

"I love surprises! How did you know?" said Sonic who came walking into the room at that moment.

"Sonic! I didn't expect you to get here so fast" said Robotnik.

"Are you kidding? C'mon Robotnik, you sound like you don't know me at all. I'm always early for the party!" replied Sonic.

"Hmph, no matter, you're too late!" said Robotnik as he pulled a switch on the side of the machine hooked up to the Chaos Emeralds. The pillars holding the Chaos Emeralds glowed brightly, and the cables connecting the pillars and machine glowed, too. Soon, the ring on top of the machine started spinning. It spun faster and faster, until electricity shot out from the center.

"Tails! Get back!" yelled Sonic as he pushed Tails behind him. The ring spun faster and faster and more and more electricity shot out from the center. Eventually, the electricity stopped, and the middle of the ring became a spinning, purple portal.

"What the-?" asked Sonic. He was interrupted by the sudden waves of energy flowing from the portal. The portal began to tear, and soon a hole opened. A green blur shoots out of the hole so fast no one has time to follow it to see where it went. After a short moment, Sonic and Tails turn around. What they see shocks them both speechless.

"Time to cause some chaos" said Scourge.
