What does the seven chaos emeralds do?

Answer 1

Chaos Emeralds

The Chaos Emeralds as they appear inSonic R

The Chaos Emeralds are, in most games, seven emeralds with mystical powers; they are a recurring feature of Sonicgames. The emeralds can turn thoughts into power,[62] warp time and space with a technique called Chaos Control,[63][64] give energy to all living things and be used to create nuclear or laser based weaponry.[65]

They are the basis of many of the games' plots, and the player is frequently required to collect them all to fully defeat Doctor Eggman and achieve the games' "good endings", super forms, or both. The methods used to acquire the Emeralds and the end-results after collecting them differ between titles in the series. Most early games require the player to find the emeralds in Special Stages,[61] while some modern games implement the emeralds as a plot element. In certain games, such as Sonic R and the 8-bit versions of Sonic the Hedgehog and Sonic the Hedgehog 2, the player is required to find the Chaos Emeralds within the zones themselves.

The Master Emerald was introduced in Sonic & Knucklesas a plot element. It resides in a shrine on Angel Island and is guarded byKnuckles the Echidna, as only those of the Echidna Tribe are able to control it.[66] The power of the Master Emerald is what keeps Angel Island afloat in the sky.[67] It can control the power of the Chaos Emeralds,[62] including neutralizing or amplifying their energies.[68]

Special StagesUsually, Special Stages were employed as a means of earning Chaos Emeralds.[61] Special Stages usually take place in surrealenvironments and feature alternate gameplay mechanics to the standard platforming of the main levels. The 16-bit Sonic the Hedgehogconsisted of a giant rotating maze, which many considered a major technical achievement.[69] The most common special stages, however, were segments with the character running through a long tunnel to collect certain items. 3D "collect item" levels, as in Sonic 3and Sonic & Knuckles, used the same perspective but had Sonic collecting all the blue-colored orbs on the surface of a giant sphere. Finally, Sonic Advance 2 employed a 3D ring-collecting stage, and Sonic Chaos(Sonic and Tails in Japan) used a variety of gimmicks for its levels. Since Emeralds of the 8-bit version of Sonic the Hedgehog were hidden in the main stages, the game's spring-filled Special Stages were merely used as a means of adding variety, increasing score and earning continues. Similarly, Sonic 3 & Knuckles, in addition to the main Special Stages, featured entirely optional bonus stages, one of which combined the rotating maze of Sonic the Hedgehog with the pinball gambling of Sonic the Hedgehog 2. Sonic Heroes contained an alternate Special Stage for a chance of earning additional lives.
