The '''Sonic the Hedgehog series''' is a video game franchise published by [[SEGA]]. The games center on the anthropomorphic blue [[hedgehog]], Sonic, who must thwart the plans of the [[evil]] Dr. Eggman, a [[human]] mad scientist who desires to take over Sonic's world with his robotic creations. In his adventures, Sonic is assisted by numerous friends, including Miles "Tails" Prower, a young [[fox]] who can fly by spinning his two tails like [[helicopter]] blades, Knuckles the Echidna, the guardian of some of the powerful artifacts of Sonic's world, and Amy Rose, a female hedgehog smitten by the titular hero. Other characters usually act as adversaries to Sonic, including Metal Sonic, a robot built by Dr. Eggman that matches Sonic's speed, and Shadow the Hedgehog, a character who can utilize powerful techniques such as "Chaos Control".
