This story is dedicated in memory of Ben Hurst who worked on SatAM and Sonic Underground, not to mention was active in the Sonic franchise for the last decade.

This story is also dedicated in loving memory of my recent friend, Eri-chan, who was always there for me when I lived in Japan. I miss you so much and I promise to keep you in my prayers always.

私はあなたを、私の耳の友人欠場。あなたは永遠に神様とされるかもしれません。


Summary: Sonic was always one to take danger on without always thinking about the precautions. However, when he is sent into an alternate dimension where the friends he knew are gone and Dr. Eggman has drastically changed, will he be able to return to his own dimension? Sonic X & SU based.

Story Notes: I am a long time Sonic fan as I remember when we had the premiere of Sonic Adventure in Japan and I remember playing it then. This story comes from two main universes:

Sonic X and Sonic Underground with Sonic and Tails' relationship from SatAM.

Eggman from Sonic X will be referenced as Eggman (as according to the original Japanese games) and Robotnik from SU will be referred to as Robotnik. Robotnik will have the bigger role in this story as well, not his counterpart.

This story also contains some video game hints that Sonic X did not cover or I might slightly modify what happened. Such as Chris on the ARK reminding Shadow that Earth is worth saving in the anime rather than in the video game where Amy did it. Secondly, I will hint the relationship of Sonic and Tails from SatAM, but other than that, this will involve the Sonic X and Sonic Underground universe mostly with a few game elements.


Chapter One – Chaos Control

"Sonic, you promised that you would help me find the last Chaos Emerald," Tails complained. Sonic grimaced as he set perched up in a tree, just outside of Tails' workshop. He had promised Tails that he would help the young kit to find the last Chaos Emerald.

Eggman or sometimes called Dr. Robotnik had managed to get five Chaos Emeralds. Knuckles, a long time friend, had the sixth emerald. No one knew exactly why the human had started to collect them in the first place, but not appears to be a big deal to everyone as it did Tails.

The young fox lately had been trying to get the last Chaos Emerald so at least that would stop Eggman from using their powers against Sonic and his friends. The hedgehog was not worried about dealing with Egg man and his dream to be a world tyrant.

"Look kiddo, we can wait a few hours," Sonic answered. He really did not want to go at all. He wanted to really just relax and nap part of the day.

"If we wait any longer, Amy will want to go," Tails bribed with a slight angered expression on his face.

'He has been doing this a lot lately. It is like he does not even care what could happen if Eggman got all of the Chaos Emeralds,' Tails thought. The two had been at very odd ends with each other as of lately. They had been spending less time with each other and every suggestion Tails made, it seemed like Sonic ignored completely.

"Amy can go then. I think I will stay around here for today. Even Eggman hasn't moved in the last few days-"

"Then that is all the more reason we should get the emerald," Tails interrupted but not before walking away from the hedgehog in an irritated manner and started to walk away.

"Hey Tails, where are you going?" Sonic asked.

"Where do you think? To get the emerald, as there is no use to wait around for you," Tails replied back, harsher than he intended as he kept on walking. He left a dazed Sonic sitting on the tree branch, staring at his best friend. Before the hedgehog had even noticed, Tails fired up the Tornado and left in search of the seventh emerald.


Elsewhere, in an alternate dimension of Mobius, the loyal triplets of the Sonic Underground walked up to their own instruments respectfully where the instruments set placed on stage. Manic, a green hedgehog who was a tricky thief appeared behind his drum set. Sonia, a pink hedgehog and the only female hedgehog in the Sonic Underground band, walked up to her keyboard. Finally, Sonic walked up to his guitar, as he heard Manic's beat on his base drum as Sonia started to suddenly play her keyboard.

These triplets were playing in a concert for the Freedom Fighters, who sought to get freedom from their tyrant ruler, Dr. Robotnik. The purposes of the concerts were not to draw attention for Robotnik's forces, but rather to encourage the local Freedom Fighters in the war against the dictator.

The concerts also provided the local citizens to remember the people who had fallen in the war against Robotnik and those who were roboticised. Many people, whether they were for Robotnik's rule or trying to have the Royal Council of Four on the throne, had lost family and friends to the only human on Mobius.

After the triplets finished their first song, Sonic talked into the microphone, "Hello everyone! As some of you might know, I am Sonic and these are my two siblings, Sonia and Manic." The crowd cheered as Sonia gave a bow and Manic waived his hand from behind the drum set. As the blue prince continued talking, he did not know he would experience a radical life change that evening nor did his siblings.


Tails could not remember how he ended up in this situation.

Wait…yes he could. He had been tracking the seventh emerald when he found another one on radar and it just happened to be Knuckles who had sensed the final emerald as well. Tails picked up the echidna and it seemed the two friends would not have any problems getting it. The young fox had been terribly wrong.

Eggman had also been on the way to get the last emerald though the problem came when Eggman's emeralds and the one Knuckles had started to glow causing malfunctions in the Tornado. The fox had been so busy trying to avoid the missiles from behind them that the kid did not notice the one coming directly towards the plane.

"Tails, come on!" Knuckles barked, as he grabbed the surprised fox by his collar and punched towards the glass, instantly shattering it. Jumping from the plane, the echidna was quick to start gliding as he felt the rush of the wind. Several meters above the duo, the plane exploded as soon as the missile landed on impact.

Tails was in a daze as he watched his beloved plane explode. However, he did notice Knuckles having trouble trying to accommodate for his weight so the kit wound his namesakes in a familiar motion and the duo landed on the ground. It was by mere luck any of the missiles avoided the two.

"Oh man, we lost the scanner to find the emerald," Tails murmured as Knuckles scouted the area. They had landed on the land that provided some shelter from Eggman's robots; however, they were very close to his current base.


Sonic had seen the news report about Eggman sending missiles right near the coast line of an ocean. The hedgehog wanted to retreat when he heard the one word he hated the most: water. It was deadly and dangerous. If he feel in…

Though the hedgehog was running as fast as he could when he saw the Tornado explode on the television, as the blue hedgehog knew he needed to see if Tails was alright. They had not ended on friendly terms just an hour ago:

"Hey Tails, where are you going?" Sonic asked.

"Where do you think? To get the emerald, as there is no use to wait around for you," Tails replied back.

'Hang on, little bro,' Sonic thought as he forced his legs to run even faster. If something had happened to Tails…he knew he would never forgive himself.


"Where is that stupid hedgehog when you need him?" Knuckles muttered in annoyance, as his fist collided with yet another robot. Eggman was scouting the area looking for Tails and Knuckles because the echidna had the last emerald he needed.

The doctor had easily picked up the last emerald while the duo was distracted from their forced crash.

"Probably snoring," Tails piped in before he could even think, his voice more bitter than he intended. Knuckles stopped walking ahead and looked at his fox friend.

"What is the matter with you?" The echidna asked, taken by surprise the tone in his friend's voice.

"Nothing, I" the fox got interrupted when a blue blur suddenly appeared in front of them.

"Yo, Knucklehead, surprised to see you here. Tails, are you alright?" Sonic stated, as he gave a smug look at the echidna and continued on before his rival could reply.

"Fine but the Tornado is trashed," Tails answered, grimacing at fate of his plane.

"Never mind that. I can sense Eggman has the last emerald, which means he has six of them. If we do not do something quick, he could harness some of their powers," Knuckles interrupted. However, the three were taken by surprise with the sound of approaching motors.

Looking up at the sky, it was none other than Dr. Eggman himself.

"Why hello Sonic, I see you finally decided to show up," he retorted.

"Sure, whatever. Will you be kind enough to hand over the emeralds you have?" Sonic stated, as if completely enjoying the presence of Eggman. Knuckles rolled his eyes in annoyance and Tails bit his lip. Something seemed off about the human.

"I would like you to meet my robot, the E-569 series," the doctor answered, as the robot came into view. It was big but what made the three heroes know for sure it was Eggman's robot was the picture of his face plastered to the side. However, the robot only had one arm and hardly any weapons that seemed dangerous at all. Sonic noted he did not even see any. Knuckles had a sweat drop form on the side of his head. The robot looked almost exactly like Big the Cat only gray and what looked like a tattoo on the side of his face with Eggman's own painted face.

"Wait, that? I do not even see any weapons!" Sonic laughed, though he could not help it. Knuckles was also trying not to snicker. The robot did not look dangerous at all.

Tails was studying the robot with intense eyes, however. No it did not have any weapons but he could tell there was something off about the robot.

"You shall see. E-569, use the emeralds!" Eggman answered.

To the surprise of the three heroes, the six Chaos Emeralds the doctor had suddenly flashed within "Big's" eyes. The emerald Knuckles had flashed a blinding white light – one that was all too familiar with Sonic – and within seconds, the hedgehog shielded his eyes. The energy from the emeralds seemed to actually burn and Sonic had to bite his lips from screaming.

Within several more seconds, the pain was too intense for the hedgehog and he felt himself loosing conscious. His last coherent thought was, 'Tails…I'm sorry.'


"One hedgehog found, sir," Sleet said through his voice calm link.

"Which one is it?" Robotnik asked.

"The wonderful prince Sonic and it appears he has been wounded by something other than our own forces," Sleet answered back.

"Interesting…" Robotnik's cold voice sounded, "Bring him back to Robotropolis, Sleet…"
