The 25 Years of Sonic the Hedgehog

Sonic Advance 2 (2002)

Taking place on an undefined island, Dr. Eggman had again begun kidnapping animals and turning them into robots so he can build the Dr. Eggman Empire. This time however, he had kidnapped Tails and Knuckles too. Learning of his friends' kidnapping, Sonic rushed off to save them. Along the way, Sonic saves a young rabbit named Cream and her Chao friend, Cheese, from Eggman after defeating his EggHammerTankII. Cream then joins Sonic on his adventure to find her missing mother, Vanilla.

Sonic soon rescues Tails from Eggman too, although Tails had no idea what Eggman was up to, and Tails joined Sonic on his mission. When Sonic finds Knuckles, the echidna has been tricked by Eggman into fighting Sonic...again. After being defeated and chided by Sonic, Knuckles comes with him to get back at Eggman. The heroes eventually track Eggman to his Egg Utopia space station, which they destroy, and Cream finds Vanilla in the aftermath, unharmed.

If the player has not unlocked the final zone for Sonic by then, he falls down to earth after destroying Egg Utopia, where he is greeted by his friends. If the player has however, the last story will unlocked. As Vanilla is by herself watching Flickies, she gets sucked into a cloaked mech piloted by Eggman, who then takes his mech into space. With Sonic and his allies arriving too late to save Vanilla, Cream begins crying, but Sonic transforms into Super Sonic and goes after Eggman. Destroying Eggman's mech, Super Sonic grabs the capsule containing Vanilla. During atmospheric reentry though, the capsule breaks apart, causing Sonic to revert back to normal. Sonic still catches Vanilla and lands safely though, and Cream shares a tearful reunion with her mother while Sonic is welcomed back by his friends. Amidst the celebration though, everyone noticed Sonic was gone, having left for his next adventure.
