Sonic the Hedgehog

Sonic the Hedgehog, also simply called Sonic, is a primarily video game-based franchise surrounding its main protagonist, Sonic the Hedgehog. In it, Sonic runs around at the speed of sound on his journeys alongside his friends Tails Miles Prower the Two-Tailed Fox, Knuckles the Echidna, and many others, stopping Dr. Eggman (formerly Dr. Robotnik) from completing whatever evil scheme he has in mind. Sonic often rivaled with Mario both back in the infamous Console Wars and in video games like Mario and Sonic Olympic games.

Gameplay
Unlike with Super Mario, the gameplay of Sonic barely stays the same. In the beginning with the first few big Sonic games, they were all similar in the basic way the player would control Sonic. But has time went on, Sega changed the way the player did, well, everything. One moment, Sonic's running around, spindashing through his enemies. The next, he's driving a car, driving next to his friends despite being times faster than his car.
