> Many theories exist on what Tiberium really is. Some, such as
Dr. Ignatio Mobius, believed that Tiberium itself is a lifeform rather than a mineral. This hypothesis seems to be based on early forms of Tiberium, which originally occurred as seemingly organic, plant-like pods. This theory is supported by the symbiotic relationship Tiberium shares with mutated lifeforms, its ability to corrupt lifeforms such as trees and convert them to spread more of the substance, and Tiberium's apparent ability to adapt over time, becoming resistant to reclamation efforts.
