I've also made the spontaneous decision that I want King Sonic as a future character, as Avalon could be an interesting location.
Those of you unfamiliar with Sonic canon may be asking yourselves "what's the deal with Sonic being a king?" Allow me to explain. See, during the late 2000s, Sonic and the Black Knight came out. In the game, a wizard and Merlin's granddaughter named Merlina pulls Sonic back into medieval times to kill King Arthur, who's been corrupted by the dark magic of Excalibur's scabbard. In order to do this, he needs to take the three Sacred Swords from the Knights of the Round Table. Namely, Sirs Gawain, Lancelot and Percival - who for some reason are alternate reality versions of Knuckles, Shadow and Blaze. Also Tails is a blacksmith and Amy is the Lady of the Lake. Don't question it. Sonic and his talking sword, Caliburn, defeat the Knights and take the swords, eventually cornering King Arthur at Avalon and striking him down. Sonic returns to Merlina with the scabbard just in time to save her from Gawain, Lancelot and Percival. Merlina drops a truth bomb by revealing that King Arthur Pendragon was just an illusion created by her grandfather (that is somehow sentient. Don't question it.) and that all along Merlina was using Sonic to get the Scabbard so she can use its magic to create the Darl Hollow and turn Camelot into an eternal kingdom. Sonic unites with the Round Table to escape with their lives and make a force field which fails to stop the Hollow but creates an opening for Sonic to get in. Sonic tries talking to Merlina which doesn't work, Merlina snaps Caliburn essentially killing him, and Sonic telepathically communicates with the Round Table through the magic of the Lady of the Lake. The four Sacred Swords combine to reveal Caliburn was actually Excalibur the whole time, and for some reason Sonic gains a suit of magical golden armor. Don't question it. It's badass. Excalibur Sonic (yes that's the name of that form) defeats Dark Magician Merlina with his superior attack points and they revert to normal with Sonic giving an exstistential monologue about life and death. Then Caliburn reminds everyone that whoever can draw and wield him is the rightful king, revealing that SONIC WAS THE REAL KING ARTHUR THE WHOLE TIME.
Yes, this happened in an official game. And due to the fact we see it in a storybook, it's technically canon.
