The Shrink Ray, also known as the Reduce/Enlarge, is an object that appears in the Sonic the Hedgehog comic series and its spin-offs published by Archie Comics. It was a device used by Dr. Robotnik for a number of times by the Knothole Freedom Fighters.
The Shrink Ray was first used against the villainous Universalamander in order to shrink him down to a manageable size by Super Sonic. Later, when the villain returned, the device was used against him again only to cause him to grow as a result of a modification made to Universalamander by Dr. Robotnik that reversed any energy turned against him. However, the Knothole Freedom Fighters overcame this challenge by creating a device designed to make Universalamander grow-and thus shrinking him once again. Sonic the Hedgehog later employed it again after his fellow Knothole Freedom Fighters were infected by Dr. Robotnik's French Frirus, which allowed him to join forces with Rotor Walrus' Auntie Bodies and combat the artificial disease.
