Description
Eclipse, later unveiled as Shade, holds the title of Moon Kingdom prince and elder sibling to Princess Milky. Operating under his Eclipse alias, he presents himself as an enigmatic, pragmatic figure detached from social norms, single-mindedly dedicated to saving the Mysterious Star. His disguise—a dark blue cowboy hat, black coat, and whip—contrasts with his regal true appearance: golden coat, navy-blue cape embroidered with royal insignia.

Shade balances calm calculation with solitary tendencies, prioritizing strategic action over emotional considerations, yet harbors profound loyalty to his family. His mother Queen Moon Malia’s deteriorating health fuels his medical ambitions, while witnessing court intrigues fuels his distrust, prompting him to secretly probe the chancellor’s machinations—a pursuit vindicated when the chancellor’s treasonous plot emerges.

Anime and manga diverge in his romantic arc. The anime traces his shifting affections from Princess Rein to Princess Fine, highlighted by his accepting her flawed chocolates, tearful reaction to her despair, and their celebratory dance post-Black Crystal King’s defeat. The manga retains his steadfast longing for Rein, hinting at mutual feelings by the finale. His rivalry with Prince Bright matures into respectful kinship as they align their goals.

As Eclipse, he strategically tests the twin princesses’ capabilities, masquerading as an antagonist while gathering intelligence to safeguard the Mysterious Star. His alliances with Fine, Rein, and allies, aided by his dragon companion Regina, underscore his covert heroism. Expertise in botany and astronomy reflects his scholarly mind.

Media-specific traits include manga-exclusive black hair, purplish-gray eyes, and ear piercings, with Eclipse as his birth name. The anime prioritizes his redemption and integration into the group, whereas the manga emphasizes lingering tension with Rein and eventual romantic closure. Both iterations cement his complexity: a guarded strategist whose familial devotion and unflinching pragmatism anchor his pivotal role in resolving crises.
