Maria Robotnik, the most well-known victim of N.I.D.S.

Neuro-Immuno Deficiency Syndrome, (also known as NIDS, Neuro-Immune Deficiency Syndrome and N.I.D.S.), is a rare, incurable and potentially fatal disease.


Professor Gerald Robotnik originally intended to find a cure to this disease to save his granddaughter, Maria. He was asked by the government of the United Federation to make immortality possible. Gerald only agreed as Maria had developed N.I.D.S. and he saw the research as a potential for a cure. Thus, Project: Shadow was created, its goal to create an immortal lifeform, but the project fell apart when the military shut it down and killed or imprisoned those involved so they could use the project's result, Shadow, as a weapon.
