===Biological beings===
While most commonly associated with AIs, this form of corruption is not limited to machine entities: given the right conditions, the Flood is capable of manipulating organic beings as well due to the Gravemind's immense intelligence as well as its powerful metaphysical abilities. Using a key individual as an unwitting puppet, for example, would be highly effective at demoralizing the enemy and generating chaos in their midst; doing so may potentially be more beneficial to the Flood as a whole than immediate biological infection.<ref name="s286">'''Halo: Silentium''', ''pages 286-289''</ref> However, instances of this occurring are relatively uncommon and were only hypothetical to the Forerunners during the [[human-Forerunner wars|first Flood outbreak]] and most of the Forerunner-Flood war.<ref>'''Halo: Silentium''', ''pages 34-35''</ref>

However, normal Flood infection also contains an incorporeal aspect. When the Flood infects a biological being, a metaphysical strain of the infection capable of surviving [[mind transfer]] procedures and the destruction of the victim's physical body. Even if the extracted essence is restored to a new body free of infection, the Flood is capable of resuming its biological infection through this fundamental corruption of pattern information. This was most tragically demonstrated with the [[Composer]] and its failure to reconstitute infected individuals' biological forms: the new bodies of Flood victims subjected to Composer processing would invariably degenerate and fall apart in a short period of time.<ref>'''Halo: Silentium''', ''pages 320-323''</ref>

Because of its highly flexible and adaptive nature, most Forerunner attempts to directly protect their AIs against the logic plague failed.
