Sir Lancelot

Sonic and the Black Knight (2009)
In the world of book about King Arthur, the mighty King became a dark knight, taking advantage of creatures from the Underworld. He became utterly invulnerable through the power of the Excalibur Scabbard and wreaked havoc across the kingdom. Merlina, the granddaughter of Merlin, desperate to defeat the dark knight, summoned a creature from another world, which turned out to be Sonic the Hedgehog. Sonic faced Arthur in battle, but Merlina stopped the hedgehog and teleported him along with herself. Three of King Arthur’s loyal knights, Sir Lancelot, Sir Gawain, and Sir Percival, were sent to kill the newly arrived hedgehog and Merlina. Sir Gawain and Sir Percival doubt the rightness of the King’s actions, but Sir Lancelot tolerates no doubt and the knights set out on the mission. Soon, Sir Lancelot finds Sonic wielding the sacred sword Caliburn and challenges him. Sonic tries to escape, but Caliburn accepts the knight’s challenge. In the duel, Sir Lancelot underestimates the hedgehog and is defeated. Sonic leaves the knight alive but takes his sacred sword Arondight.

In the end, all the Knights of the Round Table have been defeated by Sonic and using the three sacred swords, Sonic disables the invulnerability granted by the Excaliburn Scabbard and kills King Arthur, who strangely disappears in a haze like the creatures from Unerworld. Sonic deliveres Excaliburn Scabbard to Merlina, when suddenly, using the power of the Scabbard, Merlina begins to spread Underworld’s energy and send monsters into the area. The Knights of the Round Table are confused that their king was only a fake and don’t know what to do, but Sonic reminds them of their knightly duty to protect the kingdom and returns their sacred swords. Following the plan of the Lady of the Lake, Sir Lancelot, armed with Arondight, travels to the Shrouded Forest to use Arondight and other sacred swords to create a barrier around the kingdom and keep the dark energy from getting out. After putting up the barrier Sonic faced Merlina in battle but did not stand a few minutes against the power of the Dark Queen. In the end, Caliburn was broken and Sonic fell defeated. The Lady of the Lake and the Knights of the Round Table watched the battle using a magic mirror. As Sonic was about to fall, the mirror suddenly glowed and the Lady of the Lake shouted for the Knights to lower their sacred swords into it. Suddenly, three sacred swords materialized in the room where Sonic and Merlina fought and combined with Caliburn, the four swords formed the most powerful sword, Excalibur. Using Excalibur’s power, Sonic defeats Merlina, but doesn’t finish her off. Caliburn, being fixed after a transformation shocks everyone naming Sonic the true King Arthur.
