Final Fantasy Sonic X is a Massive Multiplayer Crossover (primarily focused on Sonic the Hedgehog with Final Fantasy VII elements) Adobe Flash Web Game created by BlackDevilX.

The mysterious Cain is plotting something involving a mysterious sword...but Soma Cruz manages to steal the sword and warp it away to Mobius, where it ends up in the possession of Sonic the Hedgehog. Cain's minions follow it there, kidnap Amy Rose, and attempt to kill him, but he ends up rescued by Mega Man X and Zero. From there, the group goes on a journey to take down Cain and rescue Amy.


All the games in the series so far can be found here.

"Don't touch...THE TROPES!":

  • Adaptational Badass: The True Guardian of the Stone of Chaos, is far tougher (and larger) than Slash Beast, the character he's Inspired from: X can beat Slash Beast with out any armor or special weapon; the True Guardian gave Super Sonic a good run for his money.
  • Adaptational Wimp: Metallix is far weaker than he is in Super Mario Bros. Z. Subverted, as he's actually a decoy; the True Guardian is Slash Beast.
  • Art Evolution: With each passing game, the animation gets more and more fluid.
  • A Twinkle in the Sky: While training with his new body, Sonic does this to a dummy.
  • Big Bad: Cain, who wants the Legendary Sword for his nefarious schemes.
  • Big Damn Heroes: In the first episode, X and Zero manage to save Sonic and Shadow from the Assassin robot after it defeats them.

  • Breaking the Fourth Wall: When introducing himself to Amy, Soma notes how he's been locked up "since episode 1".
  • Butt-Monkey: Tails, who gets beaten up by Aeon and then thrashed repeatedly in the battle with Aeon and Bass. And he still doesn't win the fight, even after using his Overdrive attack.
  • The Chosen One: Sonic is the one chosen to wield the Legendary Sword as detailed in the prophecy.
  • Curb-Stomp Battle: Aeon and Bass manage to easily take down Tails and Knuckles.
  • Cutscene Power to the Max: A few battles — like the one against Link — happen during cutscenes.
  • Damsel in Distress: Amy Rose is kidnapped by Cain's forces in Episode 1.
  • Dark and Troubled Past: X apparently used to work with Cain before undergoing a Heel–Face Turn.
  • Enter Solution Here: In order to get into the Temple of Time, the player must enter the first letter of the names of four legendary warriors in alphabetical order. Zephiroth gives you the name of the first one, Tidus; the other three have to be found within the next cutscene.

  • Foreshadowing: During the Episode 5 intro, Link is nowhere to be seen. Guess who betrayed the heroes at the end of Episode 6?
  • The Ghost: The Big Bad Cain has yet to be seen.
  • Heroic Sacrifice: When he realizes he's not going to be able to escape with it, Soma uses his powers to warp the Legendary Sword away before Cain's minions can get him.
  • Hopeless Boss Fight:
    • The Assassin robot Sonic and Shadow encounter in the first episode is completely unbeatable, necessitating a rescue from X and Zero.
    • A variant with Knuckles and Tails' fight with Aeon and Bass — while Knuckles is just fine, Tails can't land a hit on them until you activate his Overdrive. The next episode reveals that they lost either way.
  • Insistent Terminology: No, it's NOT a Chaos Emerald, it's the Stone of Chaos!
  • Let's You and Him Fight: Shadow fights Sonic in the first episode for seemingly no reason In-Universe (out of universe, it's to demonstrate the battle system).
  • MacGuffin: The Legendary Sword and the Stone of Chaos, which Cain plans on using for his schemes.
  • Malicious Misnaming: X derisively refers to Bass and Aeon as "Ass" and "Gay-on" respectively.
  • Massive Multiplayer Crossover: The game overall is based on Final Fantasy VII, and it includes characters from Sonic the Hedgehog, Mega Man X, Castlevania: Chronicles of Sorrow, and The Legend of Zelda.
  • Mecha-Mooks: Cain uses giant robot versions of Sonic as his minions.
  • Money Spider: Averted. Unlike with most games, the Mecha-Mooks don't carry any cash on them; being mindless automatons, they have no need for it. The game actually makes fun of you for thinking this is the case.
  • Mr. Exposition: Soma tells Amy the story behind the Legendary Sword when they're stuck in Cain's prisons together.
  • Limit Break: Overdrive Mode, which lets the heroes go into Super Mode and unleash a powerful attack on their foes.
  • Name of Cain: The Big Bad is named Cain.
  • Original Character: Several of them are used throughout the series; the most notable ones are Zephiroth and Aeon.
  • Pun: The Advancement System used to heal Sonic also upgrades his body into the Game Boy Advance-era sprites.
  • Rouge Angles of Satin: There's some of this present in the dialogue — for example, "emperor" being spelled "emporer" at one point.
  • Shout-Out:
    • Fittingly enough for a game drawing on several other Final Fantasy VII elements, the Legendary Sword heavily resembles the Buster Sword. Episode 6 reveals that it actually is the Buster Sword.
    • After Link calls them rodents, Sonic and Shadow angrily refer to him as "Keebler Elf". Link calls one of them "Mickey" in return.
  • Soundtrack Dissonance: During the scene in Episode 5 when Tails and Knuckles are curb-stomped by the villains, the cheerful 'Door Into Summer' from Knuckles Chaotix is playing.
  • Stock Sound Effects: Don't try to make a drinking game out of the number of times sound effects from Dragon Ball Z are used in the series; your liver will hate you for it.
  • Super Mode: Super Sonic is unlocked as an Overdrive Mode after you get the Stone of Chaos.
  • Summon Bigger Fish: Aeon and Bass summon the True Guardian to fight Sonic before leaving.
  • Sword of Plot Advancement: The Legendary Sword that Sonic wields is the central MacGuffin to the series.
  • Uncertain Doom: We don't find out what happened to Soma after Cain's minions got him until episode 6.
  • We Can Rebuild Him: X and Zero had to "redo [Sonic's] structure" in order to save him from his fatal wounds (aka turn him from Classic Sonic into Modern Sonic), implying this. The same thing happens to Tails and Knuckles later on.
