The Psionic Emitter, otherwise known as Egg Totem, is an object that appears in the Sonic the Hedgehog comic series and its spin-offs published by Archie Comics. It was a device created by Dr. Eggman in the year 3237.
The Psionic Emitter was used by the Northern Tundra Dark Egg Legion to control the Walrus Herd. It was placed on top of the legion's totem base, where it amplified the legion's mind control waves to secure their control over the herd. When Silver the Hedgehog used his telepathic powers to permanently free the walruses from the legion's control, the device was destroyed and the orca's sense of direction was greatly disrupted, causing them to retreat.
