A/N: Welcome to my first story exclusively under the Sonic category, specifically a rewritten work of Sonic Forces (way to join the bandwagon 3 months late, TGN). Plus, this is out of the blue since I'm still not done with my first story, Hidden Bravery, and I'm nowhere close to finishing my second work, New Brotherhood. But this idea has been lingering on my mind for so long that I had the urge to start writing this.

Before we start, let me explain that I am not a huge Sonic fan, so to speak, but I do like some of the characters. However, I did not like Forces, yet I'm writing a fanfiction based off it. If you seriously want to know why I'm doing this, please PM me. I'm not going to openly address this here because some of you probably won't care about my opinion.

Like NB, this story will be randomly updated with no defined schedule. Don't expect frequent uploads; I've reserved that for HB.

Any specific notes or references are explained in the PCN (Post-Chapter Notes) at the bottom of the page. They're denoted by numbers in parentheses in bold, italicized font. Ex.- (1)

And after that long (unnecessary) intro, let's get right into it. It's time for the Revengeful Resistance to commence.

Chapter 1: Goals in Mind

Location: Green Hill Zone

Yellow rays of sun gleamed through the white clouds that slowly floated by in the light blue sky. This region of South Island boasted so many marvelous sights. Tall trees, beautiful cascades, and of course, the green hills.

The temperature in this zone was fairly mild, but a slight breeze provided the cool feeling to whisk on one's face. Ah, yes. This was such a fantastic day. A fantastic day to just relax, take a vacation, or simply go for a run. The last of these activities has been done by a certain someone regardless of the weather. Through rain or snow, hot or cold, against the wind or through a neutral environment, he always takes pride in his asset by doing one of his favorite things.

Rushing through the many winding hills was the fastest creature on the planet. Or arguably, the entire universe. His blue quills behind his head bounced from his quick pace. His feet, consisting of socks and his traditional red sneakers, was a blur, circulating in quick motion through loop-de-loops and corkscrews without falling off. Arms were stretched out towards his posterior end, a typical gesture whenever he blazed at high speed.

Sonic the Hedgehog always enjoyed running every day. He's always eager to do something. He wasn't the kind of guy to laze around and do nothing. Two words to that: Bor-ing. He desired thrills in his life. His positive attitude was another usual trait of his personality. Albeit arrogant at times, it was to express his excitement. He usually showed off his signature smile and occasionally added a wink and a thumbs-up.

You'd expect this would be him right now. Well, guess again.

Sonic's emerald eyes were narrowed as his peach-colored muzzle maintained a frown. Usually, this expression was found for various reasons. Failing to win a battle (or race if he's facing someone fast), having his friends being threatened, pacing at a slow rate, losing his ability to run, swimming in water, as well as other factors that could a trigger a negative response out of him.

There was another legitimate reason why he was upset.

You might be wondering, what did the fat Egghead do this time? What sort of evil plot was he devising? (Did you assume his cause for distress?) Well, let's get straight to the main point.

A few days ago, his little buddy, Tails, went off to run a personal errand. Known to be a reliable mechanic, pilot, strategist, and of course, Sonic's best friend and brother, he always idolized the Blue Blur while said hero can rely on him for support in any tough situation. Anyways, on that day, he never returned to their shared home in the Mystic Ruins. When he tried contacting him on his communicator, all he received was a voicemail of his innocent, intellectual voice. It was completely off for him considering Tails always answered his calls within the first ring. That was more than enough for Sonic to enter search mode, suspecting that his friend was in trouble.

The teenage hedgehog's initial perception was that the doctor kidnapped him as a hostage or ransom so he could coax his way to retrieving the seven Chaos Emeralds, an ultimate collection of wondrous gems with mysterious, yet unlimited powers to the one who takes possession of them. He first infiltrated Eggman's island base, but he didn't find a trace, not even a piece of fur, of the kitsune. All he got was an angered Eggman, his temper way over easy, before he fled away. He ventured high and low to other locations he and Tails have been to.

Sadly, he had no luck. Because of that, he was frustrated.

Sonic was extremely desperate to find his pal. He refused to believe that he was dead. Hell, he loathed any idea of Tails being hurt or injured, even if it was from minimal torture.

To think that Tails was harmed made Sonic irate. To think that he was deceased on the other hand... the thought made him shudder.

The best he hoped for, out of all the bad outcomes, was him being captured. It meant that he was still alive, giving him some breathing room. But anything was possible, and he hated to admit that.

If in the case he was kidnapped, who, besides Eggman, would've taken him? Sonic's made tons of enemies in his past adventures, ranging from his metal doppelganger, Chaos, and Zavok of the Deadly Six. The last of these foes had a somewhat strong connection to the fox, considering the red Zeti planned to turn him into a robot after his team failed to catch Sonic. At one point, he thought Shadow had something to do with his disappearance. Then again, the black counterpart didn't know the fox too well, other than the belief that he wasn't strong as Sonic and especially not as tough as him. But he wasn't always considered an adversary to the Blue Blur. Just a hedgehog who tested his speed and strength to show how powerful he was. Or what if there was some new evil to threaten Sonic, yet have similar intentions to use his friend as bait to get what they want?

He didn't have the answers to those questions. Neither do his friends. In fact, he hasn't heard from them since. The only thing that ran in his mind was a single goal.

Find Tails, and fast.

"I know you're out there, bro. I just don't know where. But I'm gonna find you, one way or another. Just please hang on."

He zipped at a faster speed as he passed a huge waterfall. After minutes of nonstop hunting, Sonic continued to lose his patience. He couldn't give up. He wouldn't dare to give up that quickly. He's Sonic! He's made tons of promises, but none were as major as his personal goal, which was to protect Tails at all costs. If that vow was broken, he'd fail himself, not as a hero, but as a brother.

He didn't pay attention to where he was until he stopped at the edge of a mountain cliff. He could see nothing but the same usual landscape whenever he ran through the green hills. He sighed heavily as the sky turned dark, with the sun completely gone and a half crescent moon lighting up the night.

"Tails, where are you?" he said to himself out loud.

Another day, another letdown. Sonic closed his eyes, slightly groaned, and clenched a fist.

He was not that susceptible to being stressed or worried. When it involves his little brother though, it was a different story. Those bad feelings lingered in his heart, pondering if the two-tailed fox was truly okay. Sonic returned to his house in the Mystic Ruins. He'd have to try again tomorrow.

Location: ?

A dark, mysterious, yet ominous lab featured tens of glass cylinders containing DNA structure-like materials inside. They were placed all over the area, covering the majority of the room. A man with black boots walked past several of them, including one where one of his robot henchmen was polishing. The other was busy typing on a computer beside him.

"Sonic. How I hate him. And all of that loathing has been focused into this invincible instrument of destruction."

The man clenched his hands with fury, reminiscing all of his attempts of trying to take over the world and being trounced by a blue, fast, and most annoyingly, cocky creature who was known for his speed and love for action.

"Every defeat, every humiliation at the hedgehog's hands will be returned a thousandfold by my unstoppable creation."

He pushed aside the yellow robot who was cleaning the outer glass and stared at the floating specimen inside. It was a figure, with gloves, a mask, and a pyramidal stone attached to its chest.

"This is my dream come true. With this invention, I can expand the Eggman Empire across the globe and conquer the world. Mwa-hahaha!"

With the doctor laughing maniacally, the red underling peeked to the side of the computer to see his friend dangling in midair. "The boss means business this time!" Orbot expressed a hint of anxiety.

"Uh-huh," Cubot groaned, agreeing with him.

They both glanced at the dark figure. The stone on his body glimmered with a strong tint of red. A yellow pupil was visible from the eyehole of the mask. And on the backside was a very unique tail.

"Oh, Sonic... If only you knew what I've been planning this whole time. For sure, I know I'll conquer every bit of land to my advantage. And I certainly know there's no way you can beat me. Especially with him doing all the necessary work to achieve my domination. Get ready to run, Sonic! That is, when you'll be running into your eventual demise! HAHAHAHA!"

Cubot twisted his head to get a view of Orbot's concerned face. Albeit they're under Eggman's command, they were not sure if their leader has gone insane or has been that way from the get-go. Either way, they couldn't help but peer at the entity inside the capsule again. (1)

END OF CHAPTER

I find it to be a challenge for me to write something like this, because, to reiterate, I don't have a lot of experience with Sonic and the whole series. But I would highly appreciate it if I receive some feedback on what you think of this introduction, what I could improve/fix, if something is canon and I described it incorrectly, or anything else to make my writing better. (I only accept constructive criticism, not harsh comments.)

Thanks for taking the time to read! If you are interested in this story at all, please hit the follow/favorite button for future updates. Leave a review for any of the reasons I mentioned above, and I hope you enjoyed the first chapter of Revengeful Resistance! Until we meet again in Ch. 2, this is TheGameNguyener (TGN), signing off.
