Premise

Like the original comic strip, the series begins with the fall of Thule, the fictional kingdom that Prince Valiant is heir to. Valiant, his parents, and a group of survivors from the castle are exiled by the ruthless conqueror Cynan to a hostile marsh across the sea. The young prince, deeply saddened by this defeat and vengeful towards Cynan, attempts to make the best of his new life but craves some greater purpose. He finds this purpose when he has a series of dreams about a kingdom called Camelot, King Arthur, Merlin, and the Knights of the Round Table. Valiant becomes enraptured with Camelot's New Order, which is founded on the ideas that might does not make right and that truth, justice, honor and friendship should be the guiding forces in people's dealings with each other. Against the wishes of his father, Valiant leaves the exiles' settlement in search of Camelot so that he may serve King Arthur as a Knight of the Round Table.

During his quest, the prince meets two peasants who fall under the spell of his dream and join him. The first that he meets is Arn, a wandering peasant with great skills as a woodsman but who is ashamed of his class, illiteracy, and clumsiness. The second is Rowanne, the daughter of a blacksmith, who is feisty, unorthodox, and an expert with a bow and arrow. These three quickly become best friends and find Camelot together. But before they can become knights, they must undergo training, face off against various enemies, and do a bit more growing up.

Season one (26 episodes)

The first few episodes of the series deal with establishing Valiant's backstory and character, uniting him with Arn and Rowanne, and locating Camelot. Two main story arcs guide the rest of the season: 1) Valiant's training and emotional maturity; 2) Cynan's growing threat to Camelot. Through trial and error, Valiant learns the value of humility, patience, responsibility, and controlling his temper. This serves him well as he encounters various emissaries, both good and evil, connected to Cynan that indicate his ambition to invade Camelot. By the end of the season, Valiant has proven himself enough to be allowed to lead an army back to Thule and reclaim his homeland from Cynan's forces. He successfully does so with the help of Arn, Rowanne, Merlin, and his father King Williem. The season ends with Valiant bidding farewell to his parents and childhood home, returning to Camelot, and being knighted by King Arthur. There are also several stand-alone adventures that cause the trio of Valiant, Arn, and Rowanne to grow in fame throughout the kingdom.

Several key storylines begin during the first season that won't be resolved until the following year. The most obvious is Arn and Rowanne's desire to be knighted — their training and coming of age sagas continue throughout the second season. The love triangle amongst the trio (where Arn and Valiant both have feelings for Rowanne and Rowanne cares for both of them equally) is pushed to the background towards the end of the season and will resurface with new complications later on. Recurring villain Duncan Draconarius slowly undergoes a process of redemption that has yet to be completed. Another character, Denys, is briefly introduced yet will come into his own as a recurring character during the second season. Conflicts that are left to percolate until the second year include Camelot's hostilities with the Viking nation, the fallout from the massacre of the Viking peace delegation, the threat posed by a newly exiled Sir Mordred, and the beginnings of popular discontent towards Arthur's New Order. Also unknown are the final fates of the villains Robert (who is never heard from again), Cynan, Dylan, and Lord Maldon.

Season two (39 episodes)

Three main story arcs guide the overall course of the second season: 1) Valiant settling in as a knight and honing his leadership abilities; 2) Arn and Rowanne coming to terms with their insecurities as they continue to work towards knighthood; 3) the growing threat posed by the various factions of Mordred's New Dawn, a corruption of Arthur's New Order. Mordred and his partner Lord Maldon prey upon the public's prejudice against non-native Camelotians and fear of an imminent Viking invasion. The situation grows steadily worse over the course of the season as Mordred forms alliances with Camelot's enemies (including the Viking nation and the Misty Isles) and a traitor within Camelot takes steps to ensure its downfall. By this time, Arn and Rowanne have both earned their spots at the Round Table, while Valiant has risen in status to become one of the leading knights of Camelot.

Towards the end of the series, King Arthur enacts a drastic plan to foil the New Dawn, a plan that goes awry due to Maldon and causes Arthur to be buried alive. Queen Guinevere then makes the surprise move of proclaiming Prince Valiant to be Arthur's chosen heir and the new King of Camelot. Camelot continues to lose ground against its enemies until a series of surprise events turn the tide of battle: the Vikings acquire information about Mordred that causes them to end their alliance; the general public revolts against the New Dawn's forces; Valiant defeats Mordred in combat and reclaims Excalibur; and Arthur returns alive and well. The series ends with King Arthur back on his throne and saluting the future of Camelot under the New Order as Valiant, Arn, and Rowanne stand by his side.

Other notable storylines develop over the course of the season that influence the main plot arcs. One is the introduction of Princess Aleta and King Hugo of the Misty Isles — these characters add new dimensions to the Valiant-Rowanne-Arn love triangle and the danger posed by Mordred's forces. The Northland storyline also complicates the love and war arcs while providing the catalyst for Arn and Rowanne to finally achieve knighthood. Duncan Draconarious is revisited in a few episodes that place him firmly on the side of Camelot. Several stories focus on Valiant's young squire Denys, including one that finalizes the fate of season one villains Cynan and Dylan. And of course, there are the stand-alone adventures that add to Valiant, Arn, and Rowanne's growing legend in Camelot.

Some unresolved and underdeveloped plot threads are worth pointing out at this juncture. One is Valiant and Aleta's marriage, an important part of the comic strip that never transpired onscreen (the two characters end the series betrothed). Another is Rowanne's relationship with King Michael of Northland, which developed rather abruptly and lacked definite closure as the series geared up for its big finale. And the character of Lady Morgana, introduced in the first season with the potential to become a major antagonist, is forgotten about until the very end of the second season.

The characters of King Arthur, Queen Guinevere, Merlin, Sir Gawain, Sir Mordred, Lady Morgana, and Sir Kay are all major characters with origins in Arthurian legend. Also pulled from traditional lore are Camelot, the Knights of the Round Table, and Arthur's sword Excalibur. The general chivalric principles Camelot is famous for have been codified on this series as the New Order. In addition, the second season episode "The Black Rose" features the characters of King Lot, King Uther, and Queen Igraine in a flashback episode that retells the famous "sword in the stone" legend.

Like the television series, the Prince Valiant comic strip is set in the world of King Arthur and features the above list of major characters amongst its cast. Both the comics and the TV show have the characters of Prince Valiant and Queen Aleta as well as their respective realms — Thule and the Misty Isles — and Valiant's Singing Sword. There are two Arns in the comic book continuity: a young prince who is Valiant's rival for a beautiful maiden, and Valiant and Aleta's firstborn son. The latter character grows up to become a heroic figure equal in importance to his father. In the comics, Valiant's father is named Aguar instead of Williem, while his mother in the comics is unnamed (she is called Briana on the series). In the comics Thule is conquered by a tyrant named Sligon (who has a daughter and no sons) rather than Cynan. There are several situations, adventures, and minor characters from the comics that are retold in the animated series.

Rowanne and Sir Bryant are the two major characters from the television show that do not have counterparts in Arthurian legends or the long running Prince Valiant comic strip.

Video games

In 1992, King Features developed video game versions of the The Legend of Prince Valiant television series for Nintendo Entertainment System and Game Boy, only in Europe. This fighter/action game, published by Ocean, tells the story of Valiant's search for Camelot at the beginning of season one. The player controls Valiant, enabling him to walk, jump, and throw things at opponents. Typical obstacles are pit traps, water hazards and Archers embedded in the background who shoot like turrets from a stationary position.
