History VideoGame / SonicTheHedgehogChaos

* TheGoomba: Moto Bug-style 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/Spring) Motora" to make this clear in the Japanese manual, but the English versions kind of botch the connection by calling them Spring Snails and Boing-o-Bots. A giant variation of them appears as the first boss of the game in a vein similar to [[VideoGame/SonicTheHedgehog2 Egg Mobile-D]]. Variants of Buzz Bomber also recur in this game, but only have their stingers so they're more Buzzes and less Bombers.

* WakeUpCallBoss: The springing Robotnik-bot at the end of Sleeping Egg Zone Act 3 bounces and rapid-fires bullets that explode when they hit the ground. Unless Sonic/Tails is bouncing on the machine directly, dodging the bullets can be a giant pain and tell you the game's not as simple as you may have been led to believe by that point.

-->--Commercial for Sonic Chaos.

One year has passed since the six Chaos Emeralds were restored to South Island, and there was much peace and quiet ([[HotBlooded except for the occasional sonic boom]]). Then one day, an explosion was felt throughout the island, transforming the terrain in strange ways, and the animal inhabitants searched for the cause. [[VideoGame/{{Flicky}} Flicky the Bluebird]] discovered that the [[MacGuffin Chaos Emeralds]] were missing from the North Cave, and [[KidSidekick Miles "Tails" Prower]] guessed 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 [[EvilGloating gloating about his plot]] to TakeOverTheWorld and making his getaway, [[TheHero 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!

But in a first for the series as a whole, Sonic and Tails were differentiated gameplay-wise. Sonic can perform the Peel Out/Strike Dash - a technique carried over from ''VideoGame/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.

* ChickenWalker: This is the machine Eggman is operating when Sonic/Tails meets him at the end of the game (an Eggmobile on skinny legs). It can jump, crouch, and fire two kinds of shots (including a ricochet shot).

* CyberSpace: Electric Egg Zone, which has a computer board design to it. ''Sonic Chaos'' is the first handheld Sonic game to use a CyberSpace level for an Eggman-themed stage, something that ''Sonic Advance 2 & 3'' would adapt for their semi-final full-length zones.

* FinalBoss: Unlike the previous two Game Gear games, you only face Eggman's largest minions as the bosses of the Zones prior to Electric Egg Zone. Eggman himself, however, still fills the FinalBoss role and is still fought in his own Egg Walker mech at the end of the last Zone.

* TheGoomba: Moto Bug-style 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/Spring) Motora" to make this clear in the Japanese manual, but the English versions kind of botch the connection by calling them Spring Snails and Boing-o-Bots. A giant variation of them appears as the first boss of the game in a vein similar to Drill Eggman from ''Sonic 2 Genesis''. Variants of Buzz Bomber also recur in this game, but only have their stingers so they're more Buzzes and less Bombers.

* InCaseOfBossFightBreakGlass: The Robotnik/Eggman springing robot in Sleeping Egg and Robotnik/Eggman himself in Electric Egg require the player to jump on their cockpits to destroy them.

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

** The final fight with Eggman/Robotnik at the end of Electric Egg Zone Act 3 has two phases. The first pits you against an Egg Walker/Laser Walker with Eggman in it, and unlike most other Eggmobile vehicles up to this point, Sonic/Tails has to specifically hit Eggman and his cockpit directly to damage the machine. After it blows up, Eggman retreats a few paces and converts what's left of his Eggmobile into a speed ship and tries to ram the player for a OneHitKill. This is sudden death for him too; all it takes is one additional hit on him and his craft to down the Eggmobile and send Eggman scurrying for the escape jet for his VillainExitStageLeft to end the game.

* VillainExitStageLeft: After defeating Eggman/Robotnik at the end of Electric Egg Zone Act 3, he outruns Sonic/Tails to an escape platform and flees. On Sonic, if you got all 5 of the Chaos Emeralds, Eggman drops the 6th on his way out and you can pick it up to end the game. Otherwise, Sonic/Tails leave off the right of the screen like the other zones, but without the extended run.
* WakeUpCallBoss: The springing Eggman/Robotnik-Bot at the end of Sleeping Egg Zone Act 3 bounces and rapid-fires bullets that explode when they hit the ground. Unless Sonic/Tails is bouncing on the machine directly, dodging the bullets can be a giant pain and tell you the game's not as simple as you may have been led to believe by that point.

* LawOfOneHundred: How you get into the Special Stages. You grab 100 rings in a non-boss act, and you're automatically taken to them.

Variants of Buzz Bomber also recur in this game, but only have their stingers so they're more Buzzes and less Bombers.

* BossOnlyLevel: Again, Act 3 of each Zone has a small platforming pre-boss area, some sort of straightaway, and then the boss. The difficulty of ''Sonic 2 Game Gear'', however, convinced Sega/Aspect to add rings and sometimes extra lives and invincibility boxes to the act to make the fights easier.

* WhatHappenedToTheMouse: In the original Master System manual, the North Cave is briefly mentioned as a gathering place or hiding spot of the six previously collected Chaos Emeralds, but the concept is then dropped entirely from the series. However, in ''ComicBook/SonicTheComic'', [[AdaptationExpansion it is explained as location in the Frozen Zone once used to freeze the Chaos Emeralds and prevent them from wandering aimlessly due to their natural instability.]]

* 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 ''VideoGame/SonicTheHedgehogTripleTrouble'' for the boss of Sunset Park.

With six zones, three acts each, and five Emeralds to collect, it's time to hero up and save South Island!

* 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 keep them hidden and prevent them from wandering aimlessly.

* HoppingMachine: The Sleeping Egg Zone boss.

** The final boss theme is actually a remix of the ''normal'' boss theme from the Game Gear version of ''VideoGame/SonicTheHedgehog2''!

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

* SpringCoil: [[DubNameChange Hop Spring (MS)/Pogo Springs (ENG GG)/Hopping (JPN GG).]]

* 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 its front, which you can ram with the Spin Dash, bounce off of, and rinse and repeat to destroy in roughly ten seconds.

* UnderwaterRuins: Aqua Planet Zone, which contrary to its name, is still on South Island, and thus still on [[SuddenNameChange Planet Mobius/the earth/Sonic's world]].
