Knights of the Round Table

The are the lieutenants of King Arthur in Sonic and the Black Knight. Most of the members are alternate reality doppelgängers of characters from the Sonic video game series.

Origin
Not much is known about the Knights of the Round Table's past. Presumably, the group was formed by King Arthur during the period of the king's noble rule, to serve as his foremost servants and enforcers. The Knights of the Round Table themselves willingly served under King Arthur and followed his every order, bound by their honor and code of chivalry.

Arrival of Sonic
Sir Lancelot, Sir Gawain, and Sir Percival are tasked by King Arthur to track down Sonic and Merlina during Sonic and the Black Knight's opening sequence. While Gawain and Percival express their misgivings, the Knights of the Round Table nonetheless obey, and pursue Sonic across the Grand Kingdom and beyond. Sir Lancelot is fought in Deep Woods; Sir Gawain upon Titanic Plain, and Sir Percival in Molten Mine.

Despite suffering humiliating defeats at the hands of Sonic and Caliburn, the Knights do not give up. While Sonic battles King Arthur on the island of Avalon, Lancelot, Gawain, and Percival manage to track down Merlina the Sorceress in Camelot Castle. The Blue Blur arrives just in time to see Merlina reveal herself as the true villain of Sonic and the Black Knight: the Dark Queen. As the castle falls apart around them, Sonic and the Knights flee through Knight's Passage. In order to save the Kingdom, the former lieutenants of King Arthur agree to work with Sonic and Nimue to halt the Dark Queen's magic by activating four sacred stones. Sir Lancelot rushes to Shrouded Forest, Sir Gawain to Great Megalith, Sir Percival to The Cauldron, and Sonic to Dragon's Lair.

Real world mythology
Sonic and the Black Knight 's Knights of the Round Table are based on the traditional English legends of King Arthur and Camelot.
