In this game, Eggman comes into a lab and breaks a hedgehog out named Shadow the Hedgehog. Eggman thinks it is Sonic the hedgehog but then Shadow says" I'm not Sonic, I'm Shadow, Shadow the Hedgehog". The 2 hedgehogs meet a lot on their adventure and as you go through the game in the final chapter, Sonic and Shadow become friends. At the end,they become Super Sonic And Super Shadow. The game is really good. Shadow thinks of Maria a lot in this game. Maria is Professer Geralds's daughter. Maria said these words to Shadow in the game.
"Shadow, please give the people a chance to be happy. Sayonara,Shadow the Hedgehog".
Shadow thinks about Maria in Stage 4 and 9 in his story. Shadow is meant to be the Ultimate Life Form. He is also very good with motorcycles and guns.
