Gawain, along with his fellow knights Sir Lancelot and Sir Percival, was sent by King Arthur to eliminate Sonic the Hedgehog when he arrived into their world. Gawain was the second knight Sonic fought, and after being defeated, Gawain felt that he was disgraced and wanted to die, saying that only death could remove that stain upon his honor. Sonic prevented him from performing this act and asked if there was more to being a knight than serving a king.
After King Arthur turned out to be an illusion created by Merlin years ago and that it was all a plot orchestrated by Merlina, Gawain, along with the other knights, set off to use the sacred swords to defeat Merlina. After the four swords formed a barrier around the castle and Sonic defeated the Dark Queen, Caliburn revealed that Sonic was the true King Arthur of this world, and Gawain, along with Lancelot and Percival, bowed to Sonic before the hedgehog returned to his own world.
Powers and abilities
Much like his alternate reality counterpart, Gawain possesses immense amounts of superhuman physical strength, being able to deal maximum damage to his opponents with relatively few strikes. To match his strength, Gawain also possesses incredible durability that lets him withstand just as much punishment as he can deal out, reaching the point where he is hardly faced by Sonic's sword strikes.
Like most other characters in the series, Gawain can run at super speed and is able to keep up with even Sir Lancelot, who has been remarked to be as quick as Sonic. Gawain is also rather acrobatic, executing both swordplay and tricks while in midair. Also, by stretching his arms and legs outwards while airborne, Gawain can catch the wind under his dreadlock-like spines, allowing him to glide long distances through midair and can do so with great control over his movements.
As a member of the Knights of the Round Table, Gawain is a master of swordsmanship. In battle, Gawain specializes in offensive swordplay, focusing on powerful ground combo sword strikes and slashing dives, while keeping up a constant series of strikes, not allowing his opponent to lower his guard. However, Sonic has remarked that Gawain is good at defending as well. Gawain is also skillful enough with his swords to throw them as boomerangs to strike his opponents from afar and catch them when they return.
Gawain primarily wields swords bearing resemblance short single-edge axe-like twin swords. Unlike the other members of the knights of the round table, Gawain always dual-wield two twin-swords in battle where they complement his twin-fisted approach to conflict. His preferred weapon of choice, however, is Galatine, one of the legendary sacred swords, which are praised for their absolute sharpness.

In Arthurian Legends, Gawain is the son of King Lot and Morgause (also called Anna). He is also the half-brother of the villainous traitor, Mordred. He also had three other brothers, but they were all killed by Lancelot when Gawain tried to stop Guinevere's execution. Only his half-brother was spared.
Gawain's set character style is Paladin, a Power-type style. This refers to Knuckles himself being a Power-type character.
Gawain is the only Adventure Mode Character who has no Homing Attack, making it so that he has to glide head on into foes in the Legacy Missions to destroy them.
In the Arthurian Legends, Gawain is said to get his strength from sunlight, hence why he is called Knight of the Sun.
Sir Gawain made an appearance in Sonic the Hedgehog #197 as part of the comics' adaptation of Sonic and the Black Knight. Though Gawain's name was never stated in the comic, Ian Flynn confirmed his name in the comic book to be the same as in Sonic and the Black Knight.
