We need to see if the Mutagen will respond to nanobots and stem cells. Also after our first round of research, we have produced a report.

Mutagen, The Parasite, or The Plague is a virulent species of parasite, is an anomaly to all known biology, and an anomaly to regular life. This may be explained by the fact that it is most likely an extragalactic species, originating from a different galaxy. It is extremely adaptive, and mutates hosts through different stages of accelerated "evolution," where the body of biomatter accelerates its own evolution to the point of a massive biological breakdown, whereby the infection can first take place. The species can reproduce without host bodies, though this is described as a last-ditch effort, and only performed by pure mutated forms.

The only known pathway for Flood reproduction and survival is by the infestation and assimilation of other species. They do this through a form of cellular reproduction known as lysogenic replication, where the viral cells infect host cells with their own genetic code, mutating the host cells into viral forms.

Capable of surviving extreme environments ranging from -130 to +150 degrees Celsius and even underwater (in early stages of life), the Flood can withstand the harsh environments of all known colonised planets.

It would seem that the Flood can infect any living organism, but that they prefer hosts with a large brain capacity to accelerate the formation and expansion of the Hivemind Intelligence(Large intelligent mass) and the group intelligence as a whole. They are only as intelligent as the beings they infect; the more cunning the enemy, the more dangerous the Flood will be.

As the Flood spread and replicate, they will alter the environment to better suit their needs. This takes the form of biomass growing on any available surface, and the air being filled with spores. This appears to be part of the Flood life cycle and is done automatically, and leads to the development of a Hivemind.

OOC: Yes, it is. They can be biomechanically linked to a nanobot provided that certain biomechanical conditions are met. Actually, we managed to build an entire legion of super soldiers that is imbued with viral living armor from the cellular level. That living armor serves as an internal main frame for the nanobot filled exo skeleton. The nano exo skeleton, in return, supports the stats augmenters that is carefully connected to the living armor as well.
