The tyrannical Dr. Robotnik attacked Christmas Island 15 years ago. The island was mainly populated with hedgehogs, and a couple owls. There were two hedgehogs in specific named Jules and Aleena who hid their baby boy from Robotnik when he attacked. The owls kept a few of the other hedgehogs safe and evacuated most of them off of the island off of Robotnik's radar. But Longclaw, one of the owls, raised one hedgehog in particular.. That hedgehog is Jules and Aleena's child Sonic. For 15 years, Sonic was the only hedgehog on Christmas Island. When he was old enough, he roamed around Christmas Island, exploring, finding small, but exciting adventures with the only friends he has: just a bunch of animals (one of each animal from the first two classic sonic games). But when Robotnik returned to that area, Sonic defended and took out his first few Badniks, realizing that Robotnik was capturing the animals and using them as batteries so he could find the mythical Chaos Emeralds! Now the hedgehog's destiny as a hero has already begun as he takes down warships, protect islands, and meets his new friend Miles "Tails" Prower, who will eventually become his brother.

Once again, Sonic was about to trash up Eggman's place. Just your typical days, right? Well, not really, because the blue blur's impatience and bad habit of charging into things without thinking, turns into a terrible mistake.
