Plutonite

Plutonite is a fictional mineral featured in the DC Comics universe, most notably associated with the planet Krypton. It is a substance that possesses a unique ability to absorb and store solar radiation, making it a key component in Kryptonian technology. When exposed to specific wavelengths of light, Plutonite can release this stored energy in controlled bursts, powering various devices and even weapons. Its most prominent use is as an energy source for Kryptonian spacecraft, allowing them to travel vast interstellar distances.

Plutonite is also known for its inherent instability. While it can store immense amounts of energy, it is also highly susceptible to environmental factors and specific frequencies. Improper handling or exposure to certain energy fields can lead to uncontrolled releases, causing significant destruction. This inherent volatility has made it a subject of study and concern for Kryptonian scientists.

In some narratives, Plutonite has also been depicted as having a secondary effect on Kryptonians, causing them to experience physical discomfort or weakness when in close proximity to large quantities of the mineral, although this is less common than its primary function as an energy conduit. The specific properties and applications of Plutonite can vary slightly depending on the continuity and writer, but its core role as a powerful, yet volatile, Kryptonian energy source remains consistent.
