Fanfic: Sonic X: Dark Chaos
A fanfiction by Eric Neo Matrix. It can be found here at

The story is a full remake of the third and final season of Sonic X. When a young alien girl crashes on their world, Sonic and his friends discover that she is being hunted by a powerful new foe; an android fox known as Tsali the Ultimate Weapon, who has declared genocide on her people and hunted them down to extinction for reasons unknown. Our heroes go into space to stop this new enemy and find the Chaos Emeralds.

And from there, things get worse. Much, much worse.

Sonic and his friends find themselves in a galaxy engulfed in tyranny and civil war between an enormous empire of demons led by Lord Maledict and the Metarex, and threatened by invasion from the ancient enemies of the Demons, the Angel Federation. But as Sonic and friends soon discover, there are far greater horrors than mere demons and angels beyond the void.

The story is currently being heavily rewritten to increase its quality and readability, and the author has recommended not reading it until it is fully revised.

Now has a work-in-progress character sheet.

This story contains examples of:

  • Abusive Precursors: The Forerunners were an alien collective charged by Maledict and Allysion to populate the new universe 500 trillion years in the past, but they rebelled and were sealed beyond the realms of time and space. Ancient prophecy says that they will return and bring about the end times.
  • Angels Devilsand Squid
  • Artistic License - Religion: Deliberate, according to the author. The Muslims of the Angel Federation are essentially every single Islamophobic stereotype turned Up to Eleven, and the Angels are willing to commit wholesale genocide on Demon subjects out of simple hatred and self-righteousness.
  • Bad Ass: Pretty much everyone.
  • Bad Boss: Surprisingly, Maledict mostly subverts this. Despite his manipulative tendencies, he genuinely cares about the people he rules over and has great fondness for his servants. Just don't attempt to betray his trust.
  • Bittersweet Ending: Tails is dead, but Dark Tails is defeated and the universe is saved. And then the Forerunners return.
  • Big Bad Ensemble: Tsali, Maledict, and Dark Tails
  • Big Damn Heroes: Several times throughout the series.
    • Venus the Seedrian fends off Dark Tails and rescues Tails and Cosmo in Episode 62.
    • Eggman distracts Beelzebub in Episode 67, allowing the heroes to escape with Cosmo and Chris in tow.
  • Black Comedy Rape: Cosmo almost suffers this in Episode 67 at the hands of Beelzebub. Chris isn't so lucky.
  • Boisterous Bruiser: Astorath is one of these.
  • Brainwashed and Crazy: Dark Tails can turn sentient beings mad by speaking to them. This is also a side effect of exposure to Dark Chaos Energy.
  • Broken Bird: Poor, poor Cosmo. Cream becomes one too.
  • But for Me, It Was Tuesday: Maledict's response to Cosmo's "The Reason You Suck" Speech before the final battle, combined with Hannibal Lecture.
  • Chronic Backstabbing Disorder: Eggman saves Sonic's life, then he betrays Sonic, then he teams up with and betrays Sonic again, then he saves several of Sonic's friends from Beelzebub, he briefly joins with Maledict, and then he attempts to betray Maledict and gets himself captured in the process before once more teaming up with Sonic.
    • Rouge pretty much doesn't care what side she's on. She originally help Eggman, then she betrays him to serve Maledict for jewel payments, then she helps Sonic and friends before betraying them to Maledict, then she betrays Maledict and joins with Eggman again.
  • Cold-Blooded Torture: Sonic and his friends find a video of the Chaotix being tortured by Maledict and Beelzebub.
  • Cool Starship: Both the Blue Typhoon and the Dreadnought, but many Demon warships are described in detail as as well.
  • Cruel Twist Ending
  • Curbstomp Battle: The battle between Maledict and Super Sonic/Super Shadow/Super Eric in Episode 64 ends up being one of these. Even in their most powerful forms, the heroes are unable to harm the Devil at all.
  • Cybernetics Eat Your Soul: Tsali is this trope to the point of Deconstruction.
    • Venus the Seedrian is a literal example. Maledict takes her soul as part of an actual Deal with the Devil. Although he gives her great power in exchange, he curses her to slowly and painfully become a machine just like Tsali.
  • Dangerously Genre Savvy: Beelzebub. In episode 67, he kidnaps Cosmo specifically because he knew Tails would go after her. And then he deliberately makes Tails angry so he can study the resulting effects of Tails' Shroud infection. He also reactivates the Galaxy Crusher to destroy the entire galaxy from a safe distance and Kill 'em All in order to cleanly end the war. Maledict is not amused when he finds out.
    • Maledict himself is also very Genre Savvy. Part of the reason he didn't want Sonic entering the war along with the fact that he wanted to keep his son safe is because he knew Sonic would most likely ruin his meticulous master plan. And he was right.
  • Darker and Edgier: The third season of Sonic X was dark on its own, and this fic takes it to the extreme. Much of the galaxy is in ruins, torn about by civil war and malevolent gods. Numerous characters die and there is loads of graphic violence.
  • Deal with the Devil: Since the devil is an actual character, this is quite common.
    • Dark Oak is following the advice and orders of the mysterious M who is actually Maledict.
    • Tsali, nearly killed during the nuclear annihilation of Seedrius, sold himself to Maledict for revenge. The Devil gave him permission to destroy the Metarex and plunder the galaxy without fear of punishment. Tsali doesn't find out the price until later.
    • Venus the Seedrian prayed to Maledict for the power to defend her race from Tsali. He answered, although not in the way she expected.
  • Deconstruction Fic
  • Demoted to Extra: The Metarex are just one of the many different factions fighting over the galaxy. The Chaotix, Dr. Eggman, and even Sonic himself are hit badly with this, although the rewrite is adding many more scenes with them and developing them a bit more.
  • Disproportionate Retribution: Tsali was tortuously turned into a combat android by Cosmo's father Luke in order to stop the Demon invasion of the Seedrian homeworld. His response? Exterminating the entire Seedrian race by himself and hunting the survivors across the galaxy.
    • Live on a planet controlled by the Demon Empire? If the Angels attack your world, they exterminate you and the entire population outright simply because you're "living in sin" according to them.
  • Eldritch Abomination: Dark Tails full stop. Powered by Dark Chaos Energy? Check. Enough power to cleanse whole planets of life? Check. Can drive other beings completely insane by speaking to them? Check.
  • The Empire: The Demon Empire rules half of the entire universe; in the distant past, it ruled all of it. Bloated and autocratic, it is nonetheless the main governing body of the setting. The Milky Way lays on its frontier.
  • Enemy Mine: Tsali betrays Maledict and teams up with Sonic when he finds out Maledict had been manipulating him from the start and ordered the destruction of his original homeworld.
  • Family-Unfriendly Death: Loads of them.
    • Cosmo's older sister Galaxina has her head shoved into a ruptured fuel line by Tsali.
    • Venus commits suicide by impaling herself on one of her own thorn-covered vine tentacles in order to break Dark Tails' control.
    • Tails gets the most unfriendly death of them all during the final battle.
  • The Federation: The Angel Federation, led by Allysion and Jesus Desjiliac Christos was originally a group that rebelled against the Demons in ancient times. The Federation also composes two other nations, the Israeli Republic of the Tribes and the Emirate of Mecca. The Emirate and Republic are often at each other's throats; only the Angels keep them together against their common enemy.
  • Forever War: Exaggerated with the conflict between the Demon Empire and Angel Federation. It's actually called the Eternal War in-universe.
  • Galaxy Shattering Kaboom: The Galaxy Crusher, a Demon super weapon capable of obliterating whole galaxies by collapsing the black holes forming their centers. Although mothballed by Maledict long ago, Beelzebub reactivates it without his permission.
  • Gambit Roulette: The entire Metarex war is part of a gigantic gambit by Maledict to conquer the universe by creating an "Ultimate" creature strong enough to defeat the Angels. To do this, he started a diplomatic incident to start a war between the Demons and Seedrians, and then he made sure the young Tsali survived the destruction of his homeworld. Then as the conflict escalated, he used a spy to convince Luke to turn Tsali into a Chaos-powered robot, and then had him alter Tsali's programming. In the process, Tsali would go completely beserk and destroy the Seedrians from within, and then Maledict would take him under his guidance so he could be turned on the Angels. Then when the Metarex began to appear, he sent Tsali to defeat them. And to ensure that Tsali ''would'' defeat them, Maledict created an alter-ego known as "M" so he could secretly control the Metarex and lead them to their own destruction.
  • God and Satan Are Both Jerks: Where to even begin?
  • Heroic Sacrifice: Both played straight and inverted in Episode 77. Tails is forced to sacrifice himself to defeat Dark Tails and save the universe and Cosmo is the one who fires the Sonic Driver at him.
  • Jesus Was An Alien Spy: A core trope of the story. Not only Jesus, but Satan, Muhammed, all the angels, and a large majority of the Jewish prophets from the Old Testament were as well.
  • Killed Off for Real: Molly, Alice, Venus, Trinity, and Tails.
  • Love Redeems: Cosmo convinces Tsali and the Metarex to end their conflict in the last episode, helping them both realize that their lust for revenge destroyed themselves and brought nothing but pain and suffering to the galaxy.
  • Sonic I Am Your Father: Maledict created numerous "Ultimate" creatures to find a way to defeat the Angels. His first attempt resulted in Shadow, but when Gerald Robotnik discovered Maledict's true plan he attempted to sabotage the project. After the ARK incident, Maledict abandoned Project Shadow completely and began Project Sonic, resulting in the birth of Sonic the Hedgehog. However, after discovering that the hedgehog only inherited the Devil's super speed, Maledict - fond of his failed creation - shot the infant Sonic in a capsule to Mobius, deciding to spare Sonic's life and allow him to make his own future. He decided to use Tsali as his next subject instead of a hedgehog, kicking off the events of the story.
  • Mood Whiplash: All over the place, but most notable in Episode 65. The chapter ends with a romantic, heartwarming scene between Cosmo and Tails - and then it cuts to Jesus launching the Angel invasion of the galaxy.
  • Messianic Archetype: Tails becomes this by the end of the series. His Shroud infection gives him control over Chaos Energy and allows him to use the Chaos Emeralds. According to Maledict, he is even know in prophecy as the "Chosen One".
  • Morality Kitchen Sink
    • Sonic and his friends are firmly white, along with Eric and his own crew.
    • Maledict and his servants are dark grey. While they have genuine goals and motivations like order and peace, they cleanse whole planets and even entire galaxies if it suits them.
    • Tsali is black at first.
    • Venus and Tephiroth are both lighter shades of grey.
    • The Metarex are grey too, mostly because they have entirely different motivations from their canon counterparts. Rather than cleansing the galaxy of animal life, they simply wish to gain freedom from the Demons so they can rebuild their race.
  • Nuke 'em: Cosmo's mother Hertia nuked her own home planet into oblivion to stop Tsali. It didn't work.
  • Omnicidal Maniac: Dark Tails whishes to recreate the entire universe in his own image by corrupting it with Dark Chaos Energy. Of course, this puts him at odds with Maledict and Allysion - who both want to do the same thing in their own images.
  • Only a Flesh Wound: When Tails refuses to hand over Cosmo to him in Episode 73, Tsali throws him to the floor and graphically rips his heart and lungs out of his chest. Tails responds by turning into Shroud Tails, immediately regenerates his wounds, and retaliates in kind.
  • Orphan's Plot Trinket: Sonic keeps an inscribed amulet in a desk in his quarters. It's not until later that he finds out that the amulet was given to him by Maledict when he was created and that the writing reveals Maledict is Sonic's progenitor.
  • Physical God: Maledict the Devil is one of the creators of the whole universe and is essentially omnipotent. Allysion is as well, although the "physical" part is debatable.
  • Plant Aliens: Cosmo and the Metarex.
  • Sequel Hook
  • Shoot the Shaggy Dog: Several of the episodes end up like this, but Episode 68 is probably the most notable. Tsali steals the Chaos Emerald and murders Molly, and then a Demon fleet glasses the planet from orbit.
  • Shipper on Deck: In Episode 65, Team Chaotix try to get Tails and Cosmo together just like the regular episode. And just like the regular episode, all of their attempts fail. Tails and Cosmo do get together though.
  • Shoo Out the Clowns: The Chaotix essentially disappear after Episode 65, until they show up for the final battle.
  • Summon Bigger Fish: Episode 63. Tsali is finally cornered and on the verge of defeat. Cue Maledict himself appearing to face Sonic personally.
  • Super-Powered Evil Side: Tails gets one, although eventually he gains full control of it and keeps his normal personality.
  • This Is Unforgivable: Shadow's reaction to Tsali insulting Maria in Episode 63.
    • Pretty much everyone's reaction to Tsali murdering Molly after promising he would release her in exchange for the Chaos Emerald in Episode 68 and then calling in an entire Demon fleet to destroy the planet they're on.
  • Time Skip: An indeterminate amount of time passes between many of the episodes.
  • Took a Level in Badass: Cosmo, especially compared to the original series. She protects Tails from Tsali, gives a "The Reason You Suck" Speech to the Devil himself, and ends up commanding the Blue Typhoon during the final episodes.
    • Tails is the biggest recipient of badass levels, to the point where he quickly enters Mary Sue territory with all the transformations and powers he gains over the course of the series. Not only does he command the Blue Typhoon, he gains control over Chaos powers as well. The rewrite tones it down to more realistic levels.
  • Tragic Keepsake: Sonic finds a shred of Tails's glove after the final battle.
  • Waking Up Elsewhere: Sonic awakens after his fight with Tsali to find himself on a bed inside Dr Eggman's base. Turned out that the good doctor saved him from almost certain death and allowed him to recover his health during the week that he was comatose.
  • War Is Hell: Many of the planets Sonic and his friends land on have been reduced to wastelands by the Metarex conflict. A number of other planets are destroyed by the various factions during the story itself.
  • Well-Intentioned Extremist: Maledict, in many more ways than one. He's willing to unleash horrific atrocities upon millions to keep peace in the Demon Empire and stop the Metarex uprising. The Angels are not much better.
    • The Metarex are completely re-imagined as an organization of these.
  • Wham Line: "They are coming". Doubles as The Stinger
  • World of Ham
  • Wrong Genre Savvy: Sonic and his friends go off into space expecting to find their Planet Egg, beat up Tsali and the bad guys, and return home as heroes. They don't realize the kind of tale they're really in until much later.
  • X Meets Y: Sonic Tensei 40000.
