Flood

The Flood are one of the main antagonists of the Halo franchise. They are a species of highly virulent parasitic organisms that can reproduce and grow by consuming sentient life forms of sufficient biomass and cognitive capability. They are considered the greatest threat to the whole existence of life, or, more accurately, biodiversity, in the Milky Way galaxy.
