Big Boss

Yet Big Boss was still not fully dead. The Patriots used nanomachines to cryogenically preserve his body in secret as a biomort. Big Boss's genetic code was used in the Sons of the Patriots ID recognition system as the key to the Patriots' worldwide control. However, Liquid Ocelot, EVA (Big Mama), and Naomi Hunter formed a plan to revive Big Boss. Restored to life, Big Boss was reunited with his clone, Solid Snake, and was infected with the FOXDIE virus planted by the Patriots, ending Big Boss's life for good.
