Techno-organic virus

A techno-organic virus (T-O virus) is a fictional virus appearing in American comic books published by Marvel Comics. The T-O virus transforms organic material into techno-organic material. Techno-organic material resembles both machinery and living tissue. All techno-organic cells function like independent machines and carry both the virus and all information on their carriers, including memories and appearance. This allows a damaged techno-organic being to rebuild itself from a single cell.
Marvel Universe varieties of this virus include the Transmode Virus carried by the Technarchy and Apocalypse's variant created or discovered by the fictional supervillain Apocalypse.
Transmode virus.
Characteristics.
The Transmode virus is used by members of the Technarchy to turn other beings into techno-organic beings. The Technarchy can then feed upon the infected beings and drain their energy (visible as lights flowing through the infected creature). Once the energy has been drained, all that remains of their prey are brittle statues. If an infected creature is not drained of its energy, it becomes a Phalanx. Transmode-infected creatures are usually black and yellow, although they can change their color.
The Transmode Virus is highly virulent. It can transmit via skin contact (though a Technarch can prevent transmission) and will transform a creature into a techno-organic creature within seconds. Only mutants have some resistance to the virus. For instance, Doug Ramsey was infected with the virus, but his infection only progressed very slowly and he was unaware he had been infected. This may have been caused by either his own mutant facility with computer code preventing the virus from infecting him at the usual rate, or a side-effect of the fact he was not infected in the usual manner, but had picked it up after repeatedly fusing his body and genetic code with that of the Technarch Warlock.
An infected creature also gains the ability to shapeshift. They can quickly restore themselves when damaged and can interface directly with machinery. While Technarchs feed by draining other techno-organic beings, Phalanxes have the ability to directly absorb matter (both organic and inorganic).
The Phalanx also experience a loss of individuality, forming a hive mind with other Phalanx and the need to contact other techno-organic life (a safety precaution created by the Technarchy, which considers the Phalanx to be a plague and which exterminates them whenever it discovers them).
Many mutants are soon apparently revived by a modified version of the virus in the Necrosha crossover by Selene and Eli Bard. Those mutants include Banshee, Caliban, Pyro, Cypher and the Hellions, eventually culminating in Bard using the virus to resurrect the entire deceased mutant populace of Genosha.
Apocalypse's variant.
Characteristics.
It was believed that this strain of techno-organic virus was either created by Apocalypse or discovered by Apocalypse on board the Ship. This virus was actually created by Mister Sinister as a means of killing Apocalypse. This attempt failed due to Apocalypse's immense powers, and the virus fell into Apocalypse's hands. Apocalypse later used the virus to infect the infant Cable. The virus has many similarities to the Transmode Virus and the two may be closely related. Techno-organic matter of this kind usually appears as blue/grey metal.
This strain of virus is less virulent than its counterpart, needing blood contact to transmit, and usually taking a longer time to infect a person, although it can have sudden short bursts of activity, during which spikes of techno-organic matter form from the diseased body and the body's parts change their forms. Another difference with the Transmode Virus is that infection is very painful and can incapacitate a person.
Humans infected with this virus receive increased strength and the ability to directly interface with machinery. While infected material can change its shape, it is unknown whether a fully infected person is capable of shapeshifting (Apocalypse can, but he already had this power before being infected).
