An acient parasitic race
housed on Halo. It consists of three forms, the Infection form, the combat form, and the carrier form. The infenction form latches on to a host, inserts a needle like appendage, forces a match in the hosts DNA, and mutates
the host. If the host was in
tact at the time of "consumption", it is mutated into a combat form. Superior to its normal counter part, the combat form posseses superior strength and lightning speed. The hosts head is pushed back, allowing
sensory organs to form, and the hosts fingers are turned into whips. If the host was to badly damaged, it turns into a combat form. The hosts head swells enourmesly, and fills with fluid and infection forms. When killed or near an opponent, the head explodes, showering the area with
flood.
Cortana-Dust and echos, were
all thats left....we did what we had to do, a
covenant armada...and the flood...gone"
