After the events of Sonic Generations, Sonic receives a letter from Yacker, informing Sonic of a new planet to explore and the possibility of greater powers within him. Sonic sets out once again to explore it and finds himself in a new world - the desert planet. After saving a floating Helix Wisp, Sonic explains his predicament and finds out the Helix Wisp can transform into a pale blue Helix. The Helix Wisp asks if Sonic is okay, and Sonic explains that his life as a guardian was taken away from him and gives Sonic the power of flight. After Sonic destroys the cannon, Sonic creates a portal and returns back to Dr. Eggman's ship. After reuniting with Knuckles, Tails, Rouge, Amy, Mecha Knuckles and Cream, Sonic explains where he is from and reveals that he is inheriting his new powers from the Helix Wisp, as well as Yacker's letter. He sends all of the Freaks to their missions. At the end of the game, Sonic, Tails, and Knuckles create a portal and return back to Dr. Eggman's ship. However, in the middle of partying up for the festivities, Sonic receives a letter from Yacker stating that he was unable to obtain the legendary shield, and has been summoned back to the Hibiki High school where he was attending school.
After the events of Sonic Generations, Sonic continues his adventure by traveling to different locations in the game. Using the portals found in the game's hub world, Sonic can travel anywhere in the game's world to a degree. He can stand on an individual platform and fly off to the next world. He can also open a portal and travel directly to the next world, as well as some neighboring worlds. By entering a portal in the game world, Sonic can return to the corresponding world in Sonic Generations. Every world has its own story and gameplay, leading to a more immersive experience.
Sonic Colours is the first game in the series to be released on the Wii and Nintendo DS. While Sonic Colors marks the first time Sonic and Tails have traveled together to the new planet Earth, it has several gameplay elements that are common to the games in the series, such as the inclusion of the Double Dash (Sonic Dash). As is seen in several games in the series, Sonic falls into a state of \"carnophagy\", a condition where the only thing that matters to Sonic is to be able to eat as many pixels as possible. SEGA's marketing for Sonic Colours even went as far as highlighting this by including an AI system that makes Sonic act more like a real dog than in past games. Sonic Colours received critical acclaim upon its release for its graphics, level design, gameplay, and soundtrack. According to Japanese magazine Famitsu, the game sold over a million units within a month after release. 7211a4ac4a
