Sonic the Hedgehog(ソニック・ザ・ヘッジホッグ?,Sonikku za Hejjihoggu) is a video game franchise created and owned by Sega. The franchise centers on a series of speed-based platform games. The protagonist of the series is an anthropomorphic blue hedgehog named Sonic, whose peaceful life is often interrupted by the series' main antagonist, Doctor Eggman. Typically, Sonic—usually along with some of his friends, such as Tails, Amy, and Knuckles—must stop Eggman and foil any plans of world domination. The first game in the series, published in 1991, was conceived by Sega's Sonic Team division after Sega requested a mascot character; the title was a success and spawned sequels, and transformed Sega into a leading video game company during the 16-bit era in the early to mid-1990s.

It was first announced on May 26, 2010, in a press release by Sega for Italy, and it included a teaser trailer.
