Dr. Nazino was a humanoid male, a physician on Nukolee. He was the head of the Nukolee Customs Health Authority.
In 2267, Dr. Nazino disguised a bomb as a medi-analyser in an attempt to kill Prince Raviki; however, the young man haughtily refused to allow the doctor to examine him, proclaiming that only the royal physician was allowed to do so. Montgomery Scott noticed that the medi-analyser was very hot and quickly threw it away just before it exploded. Dr. Nazino was killed attempting to escape. It was later determined that he had been affected by gases from Sanduy's Comet, which triggered random bouts of temporary madness. (TOS comic: "A World Gone Mad")
