Sonic was bored as could be. Sonic and Tails were supposed to go to some island off the coast, but their plane, the Tornado, had overheated and needed repairs. But since Sonic had nothing else to do, he decided to try to stay around for his fox friend.

"Hey Tails, you need any help? I could grab the parts you need… Or something like that." Sonic asked, desperate for something to do.

" sure! But I need to go get some spare parts from inside. Be right back." Tails stated as he stepped inside.

"geez, maybe I should get going. Or maybe I should go for a run . Just as long as it isn't as boring as this." Sonic thought as he stepped inside to tell Tails that he was leaving.

" Hey, Tails! I'm going to go on a run, ok?" sonic shouted from the first floor of tail's two-story house.

"Ok! we'll go flying tomorrow. It's probably going to take me another hour or so to finish the repairs, anyways." Tails said. Though he didn't show it, he was very upset that Sonic was leaving. Sonic was his best friend and idol.

"Ok little buddy! See you tomorrow!" and with with that, Sonic ran off.

Tails was close to tears when he started working again. He wished that Sonic would actually stay every once in a while. The only way he stayed longer that a day or two was if they were on a quest. Then Tails wouldn't see him until the next quest. He was always running.

One Hour later….

Tails ran as fast as he could. While Tails was working, (A.K.A Eggman) landed an attack on the lab.

"Mhuhahaha! Soon i will kill that pesy Sonic, and his friend!"

"NOOOOOO!" Tails screamed as one of the metal claws on Robotnik's newest eggbots grabbed Tails by his two tails.

"Now it all falls into place…" Robotnik cackled evilly as he went back to his newest secret laboratory. All he had to do now was wait for Sonic to take the bait.

One day later…

Sonic was more than angry with Robotnik. He went to go check on Tails, and now he was gone, and Tail's house was destroyed. And Robotnik left a ransom note:

Dear Sonic,

I have Tails in my laboratory. If you want to get Tails back, come to my lab. I will be expecting you. And if you do not come in 3 days, then tails will be terminated.

with no regrets, Dr. Ivo Robotnik

"No regrets, huh? Well i'll make him regret it!" Sonic said. And as he walked into the debris, he found Tails's wrist communicator. It had a video on the screen, so Sonic decided to check it out. It showed Tails working on the Tornado, and tails started talking:

"Hey sonic. Just wanted to see how you were doing, but you didn't pick up. But i hope i'll be able to see you soon." then the ceiling started to collapse and the garage started to shake.

"RUN TAILS!" Sonic screamed. He couldn't help but scream at the screen. He couldn't bear his friend being captured. Sure some of his friends had been captured in the past, but he knew that something was wrong with Tails. Then he found out that Tails had been missing him just now:

Tails burst into tears: " i just want to hang out with you! You have been so distant lately! Why?!" he cried.

Then Tails looked to his right, and stared in horror. Sonic saw an eggbot in the corner of the screen, then Tails started running. Then Sonic saw none other than Robotnik riding the eggbot.

"Muhahaha! Soon i will kill that pesy Sonic, and his friend!"

"NOOOOOO!" Tails screamed. The scream was so loud, it hurt Sonic's ears.

"Darn it eggman! Why go this far?! He is going to PAY!" Sonic declared as his fur turned a darker blue. And then he saw Tails's terrified face as the eggbots metal claws grabbed Tails by his two tails. Then the screen went static. Sonic lost it. First his green irises disappeared, leaving soulless, white eyes in their place.

" Eggman, you're going to PAY!" Sonic screamed as his fur turned a midnight black. "Here we go." he smirked in a surprisingly silky yet evil voice. Then he disappeared.

At eggman's secret base…

"Everything is going to plan. Soon i will get rid of that pest once and for all!" Eggman declared as he looked at his newest prisoner in his dungeon. The prisoner was a young, yellow two-tailed fox with bright blue eyes.

" Sonic is going to defeat you again and save me!" Tails stated as he looked up at his captor.

"That's exactly what i'm counting on" eggman grinned. "I will capture him and then get rid of Sonic once and for all."

"I wouldn't count on it if i were you, Ivo." Said an unknown voice said, right behind . When Robotnik turned around, it was none other than sonic.

"EGGBOTS CAPTURE THE HEDGEHOG!" Robotnik ordered as his robots cornered Sonic.

"It"s all over, Sonic." Robotnik smirked as the eggbots closed in on Sonic.

"Sonic, watch out!" Tails said with concern in his voice.

" Don't confuse me with that faker." Sonic smirked as the eggbots got a hold of him. Then Tails could feel the negative energy being gathered in the room.

"What is going on Sonic?! What is this negative energy?!" Tails asked, afraid something was happening to his true blue hero.

" I'm not Sonic. I AM DARK SONIC!" The new self proclaimed dark Sonic declared as the negative energy released, causing the whole ceiling to collapse. When the debris cleared, all that was left of the lab was rubble. And when the rubble cleared, dark Sonic was far from even a scratch. Then sonic went to Robotnik to finish what he had started.

" Your end is near, Ivo. You're gonna pay for what you've done, you got that?!" he declared as he grabbed Robotnik by his shirt.

"You're wrong rodent. I don't know what happened to you, but you don't have the guts to have my blood on your hands, and you know it." Robotnik sneered as he thought he was right.

" Well, lucky you i'm not Sonic. Didn't i already tell you that?!" dark Sonic stated, obviously angry.

" Well 'dark Sonic', how are you different from Sonic?" Robotnik asked, teasing dark Sonic. Obviously he was testing dark Sonic's limits.

" Well, first i'm not afraid to get some blood on my hands, like i said earlier." dark Sonic restated, then started strangling Robotnik

"u-u-urk!" Robotnik started choking. He didn't expect for Sonic to actually harm him. This was not the peace-loving rodent he knew before. this, was a monster in the form of a hedgehog.

"S-Sonic?" tails said. He was unconscious and had just woken up.

"W-what's going on Sonic? Can we just go home and be glad we're safe?" Tails pleaded. He never saw his friend like this, and he never wanted to see him like this again.

"N-n-no, tails." Sonic hesitated, and for a second, his green eyes came back, but then went back to the empty, soulless eyes of dark Sonic. " He is going to die! HE IS GOING TO PAY!" and with that, dark Sonic blasted Robotnik into oblivion. Then sonic turned back to his normal eye and fur color.

"T-Tails, what happened?" Sonic asked as he collapsed and fell to the ground. Tails looked in surprise

" SONIC! no.." Tails started crying. Tails hoped that Sonic wasn't dead. Then Tails started dragging Sonic to the house.

30 minutes later…

Tails had finally made it to Sonic's house. Since Tail's house was wrecked, they couldn't go there, which would have been about 5 miles less of a trip. But at least Sonic leaves his door open just in case he wanted to go for a midnight run. So Tails went inside, and started doing first aid on himself and sonic. It was going to be a long road to recovery.

3 days later…..

Sonic woke up. He was back in his bed. Hoping it was all a dream, Sonic got out of bed and went downstairs. At first he smelled bacon, then he went downstairs to see who was cooking.

" Hey Sonic! You're finally awake! Want some breakfast?" Tails asked as Sonic came downstairs.

" What just happened? I remember passing out….." Sonic's voice trailed off. "It wasn't a nightmare, was it?" Sonic asked. Tails nodded, and Sonic started to cry. Tails wasn't supposed to know.

"Want pancakes? We can worry about… whatever happened when we're done. So sleep well?"

"N-not particularly, but at least you didn't get get hurt, Tails." Sonic stated, refusing to look Tails in the eye.

" So let's eat eat! I don't know about you, but i'm starving!" Oh, and I also made chillidogs. Enjoy!" Tails said as he started eating.

" Oh boy!" Sonic said as he started eating chilidog after chillidog.

29 minutes later….

" That was the best meal i've had in a while!" Sonic said as he started washing the dishes, Tails had insisted on doing dishes, but Sonic did the dishes anyway, since, it was his house, he was the host, and he wanted to show some hospitality. And he felt bad for having Tails take care of him for the last three days.

" Thanks! But now we need to get to business." Tails said as his expression darkened. " Just what was that? And what was that dark energy i felt when you destroyed his robots?" Tails asked

" well, it's a long story…" Sonic started.
