Sonic and The Black Knight - Plot

Plot

A sorceress named Merlina, granddaughter of the original Merlin, summons Sonic to help free the mystical realm of King Arthur, who has been possessed by an unknown evil that comes from Excalibur's scabbard, and is now ruling the realm as the tyrannical Black Knight. Sonic's speed alone will not end The Black Knight's reign, so he must take up the talking sword, Caliburn, in order to break Arthur's curse and save the kingdom. Sonic must also collect the blades of King Arthur's Knights of the Round Table and Excalibur itself if he is to restore King Arthur's sanity and return him to a benevolent ruler. Sonic is assisted in his travels by a kind blacksmith and the legendary Lady of the Lake. Facing dragons, King Arthur's warriors from the Underworld and the Knights of the Round Table (who bear similarities to Shadow the Hedgehog, Knuckles the Echidna, and Blaze the Cat), Sonic collects the blades and enters a showdown against the Black Knight. However, when the dust settles, it is revealed that King Arthur was merely an illusion, and that Merlina was using Sonic as part of her plan to become the all-powerful Dark Queen and make the kingdom last forever, but Sonic knows that such a world would never work out and fights her, but takes a severe beating the first time and Caliburn is destroyed. Sonic's resolve to stop the witch, however, is great, and with this resolve (as well as the Knights' blades), Caliburn is restored and revealed to be the true Excalibur and Sonic is turned into Excalibur-Sonic (a variation of Super Sonic). With their new power, they fight Merlina and defeat her. After the battle, Sonic convinces Merlina that, while every world has to come to an end, what matters is that everyone should live their lives to the fullest until that day comes. With the fight over, the Knights of the Round Table are about to disband (due to King Arthur's death), but Caliburn says that he is the one who chooses the king, who is Sonic, playing the role of the real King Arthur all along. After the credits, Sonic tries to tell Amy of his adventure, but she thinks he was making an excuse about forgetting their proposed date. The game ends in a fashion similar to Sonic and the Secret Rings, with the book "King Arthur and the Knights of the Round Table" changing to "Sonic and the Black Knight".
