Sonic the Hedgehog (SEGA)Sonic the Hedgehog · SEGA

SEGA's Sonic the Hedgehog stands as one of the most recognizable characters in video game history, originating from the 1991 platform game that launched on the Sega Genesis. Designed by Naoto Ohshima after an internal character design contest at Sega, Sonic was created to give the company a mascot that could rival Nintendo's Mario. The original Sonic the Hedgehog game follows the blue hedgehog as he races through side-scrolling levels at supersonic speeds, aiming to foil the mad scientist Doctor Robotnik's plans to collect the powerful Chaos Emeralds. Sonic's primary form of attack is a spin move, curling into a ball to damage enemies and destroy obstacles. The game's innovative curved scenery technology allowed Sonic's sprite to roll smoothly along slopes and loops, creating a sense of speed and momentum that defined the franchise. Composed by Masato Nakamura of the J-pop band Dreams Come True, the soundtrack became equally iconic. The game sold over 40 million copies across all platforms and established the Genesis as a competitive platform in the 16-bit era, spawning a multimedia franchise that continues to this day.
