The spikes along their bodies also have some very unique properties, especially the ones that trail the spine. They are organically-formed, psychoactive crystals that closely resemble gemstones, the most common kinds being onyx, jade, citrine or amethyst, but others have been reported as well. These spikes work as a catalyst for the species’ psychic powers and also serve to condense radiation. The interaction between these energy types remains unclear, but it’s safe to assume that it is what allows behemoths to survive in a radiation-heavy habitat. As a behemoth takes in radiation from the surrounding environment, the spikes glow brighter and brighter, taking on a light glow that diminishes quickly as their radiation levels decrease. Broken or damaged spikes will repair themselves over time.
