Sir Galahad

Sir Galahad an alternate reality version of Silver the Hedgehog, from the Arthurian world of Sonic and the Black Knight. Also known as the "Silver Knight", Sir Galahad is one of the Knights of the Round Table, said to hold almost the same power as Lancelot. His abilities make him dangerous, as he shares the same telekinetic powers as his doppelganger Silver the Hedgehog.

While Galahad has no role in the main story of Sonic and the Black Knight, he is playable in mulitplayer mode after Sonic clears the "Lancelot Returns" mission in Deep Woods. Galahad's profile can be obtained by earning 5 Mastery Stars in Knight's Passage: Legacy.

Trivia

 * According to the Arthurian legends, Galahad is the son of Sir Lancelot and Elaine of Corbenic. So in this case, Galahad (Silver the Hedgehog) is the son of Lancelot (Shadow the Hedgehog) in the Arthurian times. However, the game does not tell about this.
 * Galahad is unlocked by beating the mission "Lancelot Returns"; this is further reference to Galahad being Lancelot's son.
 * Galahad was also best known as the "Holy Grail Knight".
 * Sir Galahad's sword bears a resemblance more to a dagger than a sword.
 * Sir Galahad's voice clips were actually re-used Silver voice clips from Sonic the Hedgehog (2006)
 * According to the Arthurian legends, Galahad and Percival are companions. The co-incidence lies in the fact that Silver and Blaze are companions and Silver and Blaze are playing the roles of Percival(Blaze) and Galahad(Silver). This could possibly be the reason that Silver and Blaze were chosen to play those roles in Sonic and the Black Knight.
