History VideoGame / SonicTheHedgehogChaos

Items introduced here were the Rocket Shoes, which sends your character forward with a powerful thrust of speed and mild flight capabilities for a short period of time, and the Pogo Spring, which allows you to do extra high jumps but also for a short period of time.

* TomorrowLand: Gigalopolis Zone.

* CanonImmigrant: The North Cave mentioned in the original Master System manual is a reference to the frigid cavern of the same name from ''ComicBook/SonicTheComic''. There, the North Cave acts as a sort of natural refrigerator, used as a cooling spot for the Chaos Emeralds to prevent them from wandering aimlessly.

Released towards the end of 1993 for the {{Sega}} [[SegaMasterSystem Master System]] and GameGear, ''Sonic Chaos''--or ''Sonic & Tails'' as it's called in Japan[[labelnote:*]]Not to be confused with ''Sonic the Hedgehog & Tails'', one of the game modes in the 2013 remake of ''VideoGame/SonicTheHedgehog1''[[/labelnote]]--makes quite a few improvements upon its predecessor, the 8-Bit version of ''VideoGame/SonicTheHedgehog2''.

''Sonic Chaos'' presents a couple of firsts for 8-Bit [[Franchise/SonicTheHedgehog Sonic]]. Notably, it's the first where the Chaos Emeralds are collected via Special Stage instead of in the actual zones, the first to feature the Spin Dash, and also the first to allow you to play as Tails.

One year has passed since the six Chaos Emeralds were restored to South Island, and there was much peace and quiet (except for the occasional sonic boom). Then one day, and explosion was felt throughout the island, transforming the terrain in strange ways, and the animal inhabitants searched for the cause. Flicky the Bluebird discovered that the Chaos Emeralds were missing from the North Cave, and Miles "Tails" Prower believed that the separation of the Emeralds will cause an imbalance of chaos in the world and even lead to South Island sinking into the ocean. Not a moment after that grave deduction, [[BigBad Dr. Robotnik]] appeared in his signature mobile, the pincers underneath clutching the red Chaos Emerald! After gloating about his plot to TakeOverTheWorld and making his getaway, Sonic the Hedgehog resolved to race to the other five Emeralds before it's too late. With six zones, three acts each, and five Emeralds to collect, it's time to hero up and save South Island!

One year has passed since South Island had last seen the vile clutches of [[BigBad Dr. Robotnik]]. The six Chaos Emeralds have been put to sleep in the North Cave, cooling them down to prevent them from moving aimlessly. Suddenly, all-too familiar robots start attacking the place, and Dr. Robotnik raids the natural refrigerator, nabbing the red Chaos Emerald. Fortunately, just as the situation heated up, the remaining Emeralds become active and scatter away. Now, Sonic and his buddy Tails must venture throughout South Island to reclaim the other five Emeralds and steal the sixth back from Robotnik before it's too late. With six zones, three acts each, and five Emeralds to collect, it's time to hero up and save South Island!

* {{Acrofatic}}: Dr. Robotnik managed to keep pace with Sonic in the bad ending.

* TheGoomba: Moto Bug beetle badniks return in this game, but now have Springs mounted on their backs, meaning you can only hurt them by rolling into them. They are called "Bane (Bumper) Motora" to make this clear in the Japanese manual, but the English versions kind of botch the connection by calling them Spring Snails, Boing-o-Bots and Coconut-Bots. Variants of Buzz Bomber also recur in this game, but only have their stingers so they're more Buzzes and less Bombers.

* InconsistentDub: Unusually, ''Sonic Chaos'' has a different storyline (and mostly a different manual, for that matter) between the Master System and Game Gear instruction booklets. This is the only 8-bit title that does so. If one includes the ''Sonic & Tails'' version, that's ''three'' major variations.

** The final boss theme is actually the ''normal'' boss theme from the 8-bit ''VideoGame/SonicTheHedgehog2''!

* WarmUpBoss: [[IHaveManyNames The Tracked Bug (MS)/Lady Bug Boss (ENG GG)/Great Bane Motora Gold (JPN GG)]] from Turquoise Hill Zone. It can't even directly harm you--it's just a Spring Snail, [[KingMook but bigger and with hit points.]] Its weak spot is it's front, which you can ram with the Spin Dash, bounce off of, and rinse and repeat to destroy in roughly ten seconds.

South Island is in turmoil.

''Sonic Chaos'' presents a couple of firsts for 8-Bit [[Franchise/SonicTheHedgehog Sonic]]. Notably, it's the first where the Chaos Emeralds are collected via Special Stage instead of in the actual zones, the first to feature the Spindash, and also the first to allow you to play as Tails.

But in a first for the series as a whole, Sonic and Tails were differentiated gameplay-wise. Sonic can perform the Peelout/Strike Dash - a technique carried over from ''SonicCD'' - and for some reason he's the only one who can enter Special Stages [[LawOfOneHundred (by collecting 100 Rings in a regular act)]]. Tails is slower, but he can fly, and he has the benefit of starting the game with a couple of continues (Sonic has to work for his!). Needless to say, Tails' game is considered the easier of the two.

* {{Acrofatic}}: Eggman managed to keep pace with Sonic in the bad ending.

* TheGoomba: The Motobugs return in this game, but now have Springs mounted on their backs, meaning you can only hurt them by rolling into them.

* HoppingMachine: The Sleeping Egg boss.

* ObviousBeta: It's practically an unfinished prototype version of ''VideoGame/SonicTheHedgehogTripleTrouble'', with very blank, short level design and no real reward for getting the Chaos Emeralds.

* RearrangeTheSong:
** The final boss theme is actually the ''normal'' boss theme from the 8-bit ''[[VideoGame/SonicTheHedgehog2 Sonic 2]]''!

* RecurringRiff: Mecha Green Hill's theme is [[SonicCD You Can Do Anything]]. It's also part of the final boss theme and invincibility theme.

* TomorrowLand: Gigapolis Zone.
* UnderwaterRuins: Aqua Planet Zone, which contrary to its name, is still on South Island, and thus still on Earth/Mobius/whatever.
* WarmUpBoss: The Giant Spring Motobug from Turquoise Hill Zone. It can't even directly harm you--It's just a Spring Motobug, [[KingMook but bigger and with hit points.]] It's weak spot is it's front, which you can ram with the spindash, bounce off of, and rinse and repeat to destroy in roughly ten seconds.

* CutSong: There is one in this game. Thankfully, Sega knew it would be a ''sin'' to leave it unused and so they used it in SonicTripleTrouble for the boss of Sunset Park.

* NoEnding: Even when playing as Sonic, and clearing the game with all emeralds, all you get is a slighty different credits sequence.

* ObviousBeta: To SonicTripleTrouble. Most levels use thematics from SonicTheHedgehog2, with a few that would be used in the next game. The physics feel really weird in this game, and all the levels are extremely short with barely any enemies.

* ShoutOut: In the sound test menu, if you perform a code, Sonic will pull off a [[StreetFighterII Hadouken.]]

* UnderwaterRuins: Aqua Planet Zone, which contrary to its name, is still on South Island, and thus still on Earth/Mobius/whatever. That and there is barely any water.
