A detailed 3D concept of a colossal blue‑crystal slug with an elongated, glistening slime‑coated body. Its form is studded with sleek, knife‑shaped crystal spikes, and three faceted blade‑like eyes peer forward. Instead of teeth, its clean, geometric mouth features serrated crystal edges. On its back rests a compact cybernetic launcher, configured with a single slender bone‑style harpoon. Every surface blends slick ooze with biomechanical plating, creating an eerie fusion of organic and futuristic design.
