The Thargoid Biological Matter is an organic, alien substance with a pulsating, bioluminescent glow, showcasing a deep purple and green color palette. Its surface is uneven and textured, resembling a mix of crystalline and fleshy materials, with visible veins that pulse rhythmically as if alive. The matter is encased in a semi-transparent, chitinous shell that fractures in a web-like pattern, revealing the glowing interior beneath.
