A highly detailed futuristic demon-slayer headgear accessory for Roblox, inspired by DOOM aesthetics but uniquely original. Combine sci-fi armor plating, glowing crimson runes, and a semi-mechanical skull mask design. Include subtle battle damage, retractable antenna or blade-like spikes, and glowing red or orange eye lenses. The design should feel brutal yet sleek, as if forged in a hell-tech forge, but NOT directly copying any existing DOOM or Roblox model. Style: dark sci-fi, gritty, high-poly feel.
