After settling in Green Hills, Sonic is eager to prove he has what it takes to be a true hero. His test comes when Dr. Robotnik returns, this time with a new partner, Knuckles, in search for an emerald that has the power to destroy civilizations. Sonic teams up with his own sidekick, Tails, and together they embark on a globe-trotting journey to find the emerald before it falls into the wrong hands.

Powered with incredible speed, Sonic The Hedgehog embraces his new home on Earth. That is, until Sonic sparks the attention of super-uncool evil genius Dr. Robotnik. Now it’s super-villain vs. super-sonic in an all-out race across the globe to stop Robotnik from using Sonic’s unique power for world domination.

Sonic, Tails, and Knuckles encounter an abandoned Badnik drone which upgraded itself using parts from a junkyard, with the intention of conquering the world.

While escorting Dr. Eggman and his hapless new helper Trip through a perilous ruin, Fang the Hunter will need to muster all his cunning to overcome past mistakes and escape the coils of a fierce new enemy. Meanwhile, Eggman discovers what may be the key to his next dastardly scheme.
