Description
King Mercenare began as the benevolent King of Splendorius before ancient darkness corrupted him. His descent into evil stemmed from desperate use of the forbidden Golden Crown of Wisdom, seeking a cure for his daughter Princess Marie Angelica's illness. This act unleashed the darkness, possessing him and twisting him into the embodiment of evil. The corruption reshaped him physically into a large, imposing figure marked by thorn-like features, a horned helmet, and glowing red eyes; a later revival further augmented his form into a more muscular state.

As the leader of the Mercenares, he personified the sin of Pride among the Seven Deadly Sins. His forces harvested "Janergy" from human selfishness and hatred, aiming to fully revive him and swell their ranks. Following an initial defeat, his daughter sealed him within a statue using the Spear of Light, leaving him dormant until his servants gathered sufficient dark energy for resurrection. Revived, he launched invasions against both Splendorius and Earth, converting many Splendorius citizens into Distains during the first assault.

Trapped deep within King Mercenare lingered the consciousness of the original King of Splendorius, a remnant of humanity beneath the darkness. This inner self finally broke free during a pivotal battle with the Glitter Force. Glitter Heart, Glitter Ace, and Glitter Diamond weakened the dark hold, creating an opening. The decisive moment came when his daughter Regina, wielding the Miracle Dragon Glaive, shielded the Glitter Force from his attack and openly defied him, declaring love for her allies. Her defiance and the Glitter Force's collective power shattered the darkness's grip, freeing the true king's spirit. After King Mercenare's defeat, only a fragment of darkness remained, later destroyed with Proto Mercenare's fall. The freed King of Splendorius subsequently abdicated his throne, choosing to live on Earth alongside the reincarnated Regina.

The character draws thematic parallels to the King of Hearts and shares mythological resemblance to Kronos. The name "Jikochu," the origin of his English name, stems from the Japanese term for egocentrism, reflecting his core trait of selfishness.
