Naoto Ohshima

Naoto Ohshima is a Japanese artist and video game designer best known for designing the Sonic the Hedgehog and Dr. Eggman characters from Sega's Sonic the Hedgehog franchise. Although Yuji Naka created the original tech demo around which Sonic's gameplay was based, the character in his prototype was a ball that lacked any specific features. Sonic Team considered numerous potential animal mascots before deciding on Ohshima's design, with an armadillo or hedgehog being the top choices because their spikes worked well with the concept of rolling into enemies.
