SONIC X GAMMA: Planetary Chaos Amongst the Stars

The Chaos Emeralds are seven ancient emeralds and secret stones tied to the Master Emerald that possess unlimited power.

Those that hold them can use them to cause miracles and other feats, such as warping time and space, powering machines, and initiating super transformations.

The Chaos Emeralds have observed numerous joys and sorrows since ancient times, being the center of countless world-threatening conflicts and targeted by multiple factions on earth and beyond, who seek them for their near-limitless powers.

In the hands of villains, they have been used for doomsday weapons and schemes for world domination, and in the hands of heroes they have been used to save the world.

Over time, the Emeralds have been gathered multiple times, though they tend to scatter themselves after each usage and reset the hunt for them.

Doctor Ivo Robotnik a.k.a Dr. Eggman has returned and is now on the lookout for the seven mystical gems called the Chaos Emeralds to pursue global apprehension and create his Eggman Empire.

But, his plans are foiled once again by the infamous blue blur of Mobius named Sonic the Hedgehog and his friends he's made in his past life throughout time.

However, Eggman was not willing to lose and give up the Emeralds so easily, so he had no choice but to use the Emeralds to make his escape, but due to him abusing the power of the Chaos Emeralds, he was nowhere to be seen, not even a single trace of him.

Unfortunately, after the Chaos Emeralds were scattered across time and space, Sonic's world was beginning to crumble and fall apart and it was clear that Sonic and his friends weren't going to make it out alive.

Or so it seemed so when they were all rescued by mysterious warriors and were sent to a realm that was like Sonic's, but everything was so different and futuristic.

With new friends, rivals, and allies by their side, Sonic and the others must travel the globe to find the Chaos Emeralds before they fall into the wrong hands and find Eggman.
