Neuro-Immuno Deficiency Syndrome, also known as N.I.D.S., is a subject that appears in the Sonic the Hedgehog comic series and its spin-offs published by Archie Comics. It is a rare, incurable and potentially fatal disease.
Not much is known about Neuro-Immuno Deficiency Syndrome, although it appears to be a disease that a person develops rather than contracts; Buns Rabbot got N.I.D.S. when it developed in her spine. It also appears to compromise a person's immune system.
Professor Gerald Robotnik set out to find a cure for N.I.D.S. after his granddaughter Maria developed it, and used the United Federation's Project Shadow as a means of doing research. Unfortunately, the termination of the project by the government meant that no cure was ever developed. Others have tried to cure N.I.D.S. in recent years; Dr. Ivo Kintobor of Moebius successfully made a medical suit that stopped the disease from progressing with a stasis field, but forced the victim to stay in the suit.
- This disease could be based on HIV/AIDS (human immunodeficiency virus/acquired immunodeficiency syndrome), a real-life infectious disease.
