ソニック・ザ・ヘッジホッグ/ Sonic the Hedgehog

Sonic the Hedgehog is a 2D side-scrolling platformer developed by Sonic Team and published by Sega for the Genesis/Mega Drive. Players control Sonic the Hedgehog, who can run at near supersonic speeds and sets out on a quest to defeat Dr. Robotnik, a scientist who has imprisoned animals in robots and seeks the powerful Chaos Emeralds.

In his attempt to steal the six Chaos Emeralds and harness their power, the mad scientist Doctor Robotnik has trapped the animal inhabitants of South Island inside aggressive robots and stationary metal capsules. Sonic the Hedgehog sets out to thwart Robotnik's plans by freeing his animal friends and collecting the emeralds himself.
