Design a grim underwater figure: DREDGER-9, a hulking, pressure-hardened enforcer who stalks the flooded corridors of a long-forgotten deep-sea colony. His body is encased in a massive, corroded brass diving suit, bolted together with age-blackened rivets. The dome-shaped helmet features a cracked, fogged viewport glowing faintly green from within, hiding a barely visible silhouette—something human once, now warped. Thick tubes coil from his back into oxygen tanks encrusted with barnacles and coral. His limbs move with hydraulic weight, and each footstep sends out muffled clangs through the ocean gloom. A dull hum resonates from his core—an ancient pump still ticking. His color palette is weathered brass, algae-stained teal, and abyssal black.
