Virus was a prospective member of the Legion of Super Heroes, but she was rejected. She had poor control over her ability to cause others to be sick. Obviously her powers are causing others to be sick.
The BG is from Pixel Lab, was made by Remco. Nice website where they have free C4D 3D models.
Stay in good health, take your vitamins and mineral. Don't get any viruses, keep that inmune system high. Til' next time folks.
