Superman: The Kryptonite Spectrum (2025-)

Four new mineral formations, each a distinct color, have been catalogued from deep space. Superman and Batman are conducting a series of controlled exposures in a secure Fortress of Solitude laboratory. The procedure is methodical, clinical. Each sample induces a unique physiological response in the Kryptonian subject, recorded and analyzed in real-time. The data is critical; the potential for these substances to be weaponized by any number of Earth's hostile factions makes containment the only priority. The sterile light of the monitors reflects off the crystalline surfaces, mapping unknown vulnerabilities onto a living body.
