Excalibur is the famous sword of King Arthur, sometimes called the 'Sacred Blade'. What is not in the history books, however, is that Excalibur is, in fact, the Elemental Blade of the Sky. This means that its wielder can control Fire, Light, and Air. It also has the unique effect of encasing its wielder in a suit of Golden Armor.
King Arthur was the original owner of the blade, but it appears that the weapon has selected Sonic the Hedgehog as its new wielder.
- Sonic being the new wielder of Excalibur is based on the game Sonic and the Black Knight, where Sonic's Sacred Blade, Caliburn, transformed into Excalibur.
