Infinity Stones

The Infinity Stones are powerful artifacts that exist in certain realities of the multiverse, with the power to control and influence different aspects of said realities.

Vultroverse

Originally, the stones were unknown for most of time. They were reduced to atoms some time in the mid 21st century by an unknown entity, preventing any possible conflict that might arise over their power. Thanks to Solidus the Werewolf making contact with Earth-7642, he and Dr. Eggman became aware of their existence. In the Vultroverse, they are known as the Infinity Emeralds.

Dr. Robotnik, eager to obtain the power of the stones, travels back in time and causes a war for the stones in the early 21st century.

In the Vultroverse, the emeralds are named after components of music.

• Tempo - Manipulates and controls time. Color is lime green.
• Groove - Reveals hidden knowledge about all living beings. Color is sky blue.
• Timbre - Temporarily alters the appearance of objects. Color is red.
• Harmony - Influences and controls minds. Color is golden yellow.
• Melody - Draws and amplifies natural power from the surrounding environment. Color is purple.
• Metre - Manipulates and duplicates matter. Color is pearl white.

There was also the Rhythm Emerald. This was a fake pink-colored emerald created by Dr. Robotnik as a distraction to the Avengers. It was claimed to control the distance between points in space, a power actually possible with the Metre Emerald. The tendency for gems of power to come in groups of seven added to its credibility.
