The Sun King possessed significant authority; he and his siblings wielded control over the seasons on the Forest Moon of Endor through the use of the season scepter. His sisters included the Flower Queen and the Leaf Queen, and the Snow King was his brother. In the year 3 ABY, the Snow King began a relationship with Odra, the Duchess of Sleet, who then orchestrated the theft of the scepter from the Sun King. Consequently, the Snow King plunged a substantial portion of the forest moon into a state of perpetual winter.
To resolve this critical situation, the Sun King and his sisters sought assistance from the Ewoks residing in Bright Tree Village. Through the valiant actions of Wicket Wystri Warrick and his companions, Odra was ultimately defeated, the scepter was recovered, and the natural seasonal cycles were restored.
The Sun King, alongside his siblings, initially held a position of considerable importance on the Forest Moon of Endor. At some point either during or before the Imperial era, the Sun King and his siblings acquired the season scepter, a relic imbued with the Force that granted its wielder the power to manipulate the moon's seasons. This artifact also served as a formidable weapon. The Snow King established his residence within a palace situated near the Ewoks' settlement of Bright Tree Village. While not particularly grand, the structure featured a sizable pool.
In 3 ABY, Odra, the Duchess of Sleet, successfully seduced the Snow King. Following the commencement of a tumultuous affair with the Duchess, Odra froze the Snow King's heart and, under her influence, he dispatched his Iceheads to the Sun King's palace with the mission to steal the season scepter. The Sun King, who was relaxing with a group of furry "dudes", was initially unaware of the theft. When he finally noticed, his drink had been frozen by the infiltrators. Terrified, he hid under his deck chair, allowing the Iceheads to escape with the scepter with ease. Shortly thereafter, Endor was plunged into a profound freeze due to the scepter.
The Leaf Queen reached out to Logray, the Ewok shaman of Bright Tree Village, seeking assistance. However, the elderly Ewok was not present, and the message was instead received by the young Ewok Wicket Wystri Warrick. Unable to locate Logray, Warrick, accompanied by his friends Kneesaa a Jari Kintaka, Teebo, and Latara, journeyed to the Sun King's palace via flying leaf. During their journey, Kintaka was captured by the Iceheads.
The remaining three Ewoks made it to the palace, where the Leaf Queen introduced herself and her siblings, explaining the situation and the Sun King recounting the circumstances of the scepter's loss. While the Leaf Queen continued her attempts to contact Logray, the Ewoks, without informing the Leaf Queen of their intentions, proceeded to the Snow Palace to rescue Kintaka. They successfully infiltrated the palace, and despite being discovered by the Duchess, they ultimately defeated Odra, shrinking her, restored the Snow King to his original state by thawing him out, and liberated Kintaka.
The Sun King, accompanied by his sisters, Logray, and Chief Chirpa of the Ewoks, arrived after the battle. The Sun King reclaimed the scepter, praising the Ewoks for their actions. The Snow King then restored Endor's weather to its natural state. Years later, in a 12 ABY paper, Professor Mankuskett, the Chair of Metagrowth and Polymorphism at the University of Sanbra, described how magic on Endor had transformed "local kingpins into weather-controlling warlocks."
The Sun King exhibited an extremely relaxed demeanor, often found lounging on the beaches of Endor with his "dudes," a term he was particularly fond of. In contrast to his sister, the Flower Queen, who frequently concerned herself with matters of state and her appearance, he displayed a complete lack of concern. He possessed brownish-yellow hair, beige skin, and eyes.
The Sun King made his debut in "The Season Scepter," which was the thirteenth episode of the second season of the animated television series Ewoks, and it premiered on November 1, 1986.
