In the episode " A Rick in King Mortur's Mort " (Season 6, Episode 9), Morty inadvertently becomes the King of the Sun after receiving a solar sword from a knight while waiting in line for food. The episode is a parody of Arthurian legends, specifically the films A Kid in King Arthur's Court and Monty Python and the Holy Grail , as well as high-fantasy tropes like those in Game of Thrones . Key Plot Developments
To end the war, Morty pretends to commit the sacrifice using a fake prosthetic provided by Rick. When the ruse is nearly discovered by high-tech scanners, Rick and Morty fake their deaths by jumping into the sun's plasma, a meta-reference to the "Vat of Acid" strategy. Character Growth and Themes
By debunking the knights' superstitious beliefs with basic science, Morty inadvertently disbands the order, destroying the "Scepter" that maintained a fragile peace treaty. This triggers a "Solo War" between the planets of the solar system, with each world parodying different fantasy or sci-fi themes (e.g., Mars as John Carter , Venus as vampires).
Morty discovers that becoming a Knight of the Sun requires a ritualistic castration—throwing one's penis into the sun. His refusal to comply leads to him dueling and accidentally killing the King, which forces him into the role of the new ruler.
