Chaos Emeralds

The Chaos Emeralds are powerful items used by the Sonic Team.

Chaos Control
Using Chaos Control, Sonic and his friends have the ability to turn into Super and Hyper forms, it can also manipulate time, space and reality, and it gives Tails teleportation abilities.

Super Forms
One of the most powerful things in the Sonic franchise, there are many incarnations of the Super forms.

The Original Super Sonic, is one of the only incarnations that doesn't have a time limit, the characters can stay in this super form, as long as they need.

In Super forms, the characters can breath underwater, are invulnerable and are imune to almost everything. In this form, they can jump higher than normal form and can travel at the speed of light, it's abilities are far more powerful than when they're is in his base form and they're even able to fly.

The creator of Sonic has stated that "Super Sonic can travel so fast that he can freeze time.", it was also stated that, if going all out, Super forms' speed can be limitless, however, since he starts at the speed of light, he needs to charge energy to get infinite speed, and it may take some time.

The characters can stay in super form for days on end, however, only the original Super forms can stay super for as long as he needs, and there are afew ways that Sonic can lose this form:

1: Eggman created technology to drain the emerald power from Sonic.

2: Other emerald energies, such as Knuckles' Super Emeralds, are powerful enogh to one shot Super Sonic.

3: Beings with Universe Busting power, such as Solaris, can cause damage to Super Sonic.

Super Sonic, Super Shadow and Super Silver have teamed up before, to defeat Solaris, so, in terms of power, it's safe to say that Super forms are powerful enogh to destroy 1/3 of the universe.

Hyper Forms
Hyper forms are twice as fast and powerful as Super forms. Super forms can travel at the speed of light, while Hyper forms can travel two times the speed of light, that's 1.3 Billion MPH, Hyper forms also can teleport small objects and enemies.

The only problem with this transformation is it's extremely short time span, the characters can only stay Hyper for about 1 minute, while the original Super forms can stay Super as long as he needs to.

This form is no longer canon to the Sonic timeline.
