Nimue



Nimue, more frequently referred to by her title The Lady of the Lake, is an alternate doppelganger of Amy Rose encountered by Sonic during Sonic and the Black Knight. She is a skilled enchantress, and former guardian of the sacred sword Excalibur.

Overview
At Merlina's behest, Sonic and Caliburn journey to Nimue's home in Deep Woods in their quest to determine how to blunt the power of Excalibur's scabbard. Sonic is predictably unnerved by the Lady's resemblance of Amy Rose, but Caliburn remonstrates the hedgehog and they enter the laketop pavilion.

Nimue blames herself in part for the present dire state of the Grand Kingdom, as she was the one who initially gave Excalibur to King Arthur, only for the power of the scabbard to corrupt the once-noble King. She agrees to help Sonic only if he can prove himself a true and honorable knight who will not be similarly bewitched, and assigns the hedgehog three tasks to demonstrate his chivalry.

After Sonic has completed the first task, liberating King Arthur's prisoners in Camelot Castle, Nimue magically disguises herself as a distraught child whose fellow villagers have been kidnapped by a dragon. The hedgehog's heroism in saving the Arthurian folk convinces the Lady of Sonic's just intentions, and she tells Sonic how to negate the scabbard's power using the sacred swords wielded by the Knights of the Round Table.

Later, during Sonic's battle against the Dark Queen in the Dark Hollow, Nimue's reflecting pool allows her and the Knights to communicate with Sonic and Caliburn.

Trivia

 * In the King Arthur/ Holy Grail legend, Nimue is the adopted mother of Sir Lancelot.
 * She is also noted to be the one who created Arondight out of stars and the one who gave it to Lancelot.
 * Unlike the other Arthurian-reality-versions of Sonic's companions, Nimue is not playable in Sonic and the Black Knight's multiplayer mode (although Amy Rose is playable).
 * In Arthurian legend, Nimue is the one who killed Merlin the Wizard by tricking him into teaching her sorcery. As a result, she double crossed him and trapped him in a trunk of a tree. In some versions, it is a cave made of, or closed off by crystal, and sometimes, he is held at the bottom of the ocean.
 * In Arthurian legend, it is noted that she goes by many names, mostly Nimue, Vivien, Vivienne, and Niniane.
 * Once Sonic realizes that she isn't Amy, he becomes much friendlier around her and even puts his arm around her. This implys that Sonic does have romantic feeling for Amy, but he just gets nervous when she gets eccentric.  This is further supported by Sonic agreeing to go on a date with Amy which is why he was nervous when seeing Nimue because he knew that Amy would think that he stood her up when in reality he was brought into another world.
