Dr. Ivo Robotnik is back and has released Chaos Zero from the Master Emerald. Chaos Zero watches over the Master Emerald Shrine on Angel Island. Now he wants to use Chaos Zero to destroy Station Square and build "Robotnikland". Chaos can grow stronger with every Chaos Emerald he "eats". When he gets all 7, it's all over... but not while Sonic's around. Along with Tails, Amy, Knuckles, and new characters E-102 Gamma and Big The Cat, Sonic must save Station Square in his hugest adventure yet. Written by

Did You Know?
At the Sonic Adventure conference in 1998, pamphlets were passed out advertising it. One of the pictures showed a screenshot from the first Sky Chase minigame, which included a dragon attacking the Tornado. This dragon never made it into Sky Chase (nor anywhere else) in the final version of the game. Speculation is still extensive regarding the dragon's origins and what purpose it could have served.

The same events in other peoples stories happen differently in terms of what is said by each character, also the fights are different (ie. Sonic and Tails both fight Knuckles, but Knuckles only fights Sonic). See more
Look! Chaos has absorbed all of the emerald's power! He must be sealed in the Master Emerald now!
How can that help? It won't change the way he feels on the inside! His heart will remain in turmoil, and his anger just won't vanish! He'll just be trapped... forever!
