Créature surnaturel : loup mécha dans des grottes cristallines

Imagined non-existing deep-sea unknown blending equine and marsupial traits, colossal whale-sized, depicted in documentary photography style in a crystal caves habitat. Anatomically believable design — coat, scales or skin texture coherent, eyes and limbs in plausible proportions. Single creature, calm posture, environment provides natural lighting and scale reference. No humans. No animal cruelty, injury, blood or gore. No monster-of-the-week horror — this is a wildlife-style render of a believable invented species. Specifically: cybernetic mecha wolf. Target search intent (rendered visually, no on-image text): "creature surnaturel" (fr).
