LEGO Sonic the Hedgehog is an Unofficial LEGO Theme that will probably never be released. In order for this to happen LEGO would have to sign an agreement with SEGA. A problom this theme could create is hard to shape the heads. LEGO and Sonic the Hedgehog fans would like this however. And if LEGO Mario was also released, it would bring the Mario vs. Sonic feel. Most of the sets would probably contain Dr. Eggman Robotnik's machines and Eggman himself. Some of the other sets could contain some of Sonic's friends. These friends would be Knuckles, Shadow, Silver, Rouge, Blaze, Mike Prower AKA. Tails, Amy, Cream & Cheese, and Chris. Shadow could have his Rocket Shoes as part of the back of his minifigure if it were released. Dr. Eggman could be in Titan Sets that have his Final Boss machines. There could be a special set with Super Sonic, Hyper Sonic, Super Knuckles, Hyper Knuckles, Super Tails, Hyper Tails, Super Metal Sonic, Hyper Metal Sonic, Super Shadow, Hyper Shadow, Super Silver, and Hyper Silver. There could also be a video game called "LEGO Sonic the Hedgehog".
