Neuro-Immuno Deficiency Syndrome, (also known as NIDS, Neuro-Immune Deficiency Syndrome and N.I.D.S.), is a fictional, rare, incurable and fatal disease.
It was originally intended by Professor Gerald Robotnik to find a cure to this disease to save his grandaughter, Maria. He was asked by the government to try and make immortality possible. Gerald at first refused but then Maria developed N.I.D.S. and he said he'd do it to save her. Thus, Project Shadow was created, a unique immortal life form that would hopefully allow humans to live forever; but the project failed when the military shut it down and killed or imprisoned those who were involved. It is most likely an STD, since in Sonic X, Shadow states that Maria was born with it, but it has also been stated to be contagious, meaning that she mostly likely received it from her mother, who probably contracted it during (or before) her pregnancy with Maria. Based on it's name, it is most likely a disease that affects the nervous system while also weakening the immune system, to the point of being unable to resist illness, as is evidenced by its name ("neuro" comes from the Greek word "neuron," meaning "nerve" and in medical terms, refers to the brain and nervous system. Immuno-deficiency implies a weak immune system).
Others have tried to cure N.I.D.S. in recent years; Dr. Ivo Kintobor in particular, who has successfully made a special suit, the Omega Care Unit, that stops the disease from progressing, but forces the victim to stay in the suit.
Buns Rabbot suffers from the disease in the comic series.
- This disease could be based on AIDS, a real-life disease.
