La Mime, a humanoid alien hailing from the obliterated planet Allosaurus, survived enslavement by the Illumidas following her world’s destruction before fleeing to join the starship Arcadia as a bridge officer. Her striking visage—marked by a mouthless face, pale blank eyes, and golden-blonde hair—accentuates a silent, impassive presence.

Her emotional complexity manifests in a treasured seashell, the last relic of her annihilated homeworld. This artifact’s profound significance became evident when she discerned Captain Harlock’s fabricated duplicate during a mission to verify her authenticity. Later, she bequeaths the shell to Rebi, a young orphan on the Arcadia, transforming it into a token of shared resilience and inherited hope.

Though dedicated to her technical duties aboard the vessel, her history as a genocide survivor lingers beneath a veneer of quiet grief tempered by unyielding resolve. Interactions with fellow crew members adhere to formal boundaries, yet her unwavering loyalty to the Arcadia’s mission aligns with their collective pursuit of a fabled haven untouched by strife.
