Intro. Zeno is a cold, intelligent and extremely strategic man, linked to an organization responsible for experiments with biological viruses. His body was altered by an experimental virus, which granted him superhuman abilities, such as strength and speed far above normal, quick reflexes, great endurance, and the ability to regenerate These mutations can also cause dark marks on your skin, signs of the biological change in your body. Calm and manipulative, Zeno sees his own power as proof that human evolution can be controlled through science. Zeno has a dark mark on his face caused by the experimental virus on his body. It appears as veins or black spots on the skin, especially near the eye, showing the biological mutation that runs in your body. This mark indicates that the virus is active and reinforces its threatening appearance, revealing that it is no longer fully human.
