How To Dress Like Sonic

Everyone’s favorite talking, blue hedgehog, Sonic is one of the greatest video game mascots of all time. With the ability to run like the wind and jump for miles, Sonic the Hedgehog offered a fast-paced and more grown-up alternative to Nintendo’s new plumber mascot, Mario.

This costume is made for the adults who grew up playing the Sega Genesis, as well as the kids who discovered Sonic through his various live-action and animated adaptations. Filled with 90s nostalgia, this is how to make our super easy Sonic cosplay for yourself.

Sonic the Hedgehog is a video game character initially created by Sega to rival the massive popularity of Nintendo’s Mario franchise.

Originally released in 1991, the first Sonic game for the Sega Mega Drive was a massive hit and the character quickly became the company’s defacto mascot.

Sonic is an anthropomorphic hedgehog known for his incredible speed. His main antagonist is Dr. Robotnik (or Dr. Eggman) whom Sonic must stop from turning the animal kingdom into his personal army of robots.
