Not to be confused with Samhain from The Real Ghostbusters or Samhain (RPG) or Connla

Samhain was a Celtic witch-god worshiped largely by practitioners of black magic in the Middle Ages. [1]


In the present, Samhain first manifested in Central Park. [2] For an unspecified amount of time, Samhain observed the Ghostbusters until he was sure of their power and had everything he needed. One June, Egon Spengler and Winston Zeddemore took a break and treated themselves to some Popsicles. Samhain watched them from atop a tree nearby. Egon thought he felt a sinister fall breeze from the park. He decided to take some readings later. Samhain stated Egon would find nothing. He vowed to return for the Ghostbusters later and they wouldn't see him coming. Samhain expanded the window to the other side on October 31, when ghosts could most easily cross over to the physical plane. Samhain minimized its weaknesses by hiding its true name, a tradition from ancient times in which knowledge of a true name gave a measure of power over an entity. Samhain summoned lesser entities to it and siphoned energy off of them like batteries. Samhain's power was increased exponentially. [3] He projected darkness over New York City and turned day into night. He planned to end all life with eternal autumn. The Ghostbusters attacked Samhain with Proton Streams, Boson Darts, and Proton Grenades but they were ineffective. They changed tactics and trapped the lesser entities. Samhain was eventually weakened and trapped.


On June 26, 2016, during the Crossrip Podcast Episode 227, Erik Burnham clarified the details about Samhain in the Tobin's Spirit Guide by Insight Editions would be used in the comic. Samhain was planned to appear in the International arc but there wasn't any more room as the writing went on from 2015 to 2016. Burnham still wants to use him at some point. [4]

On November 29, 2016, Erik Burnham revealed Samhain was originally involved in the story for Ghostbusters International Issue #7 but a different route was taken with Banshees. [5]


Insight Editions

Insight Editions

Samhain has the ability of minor environmental manipulation. Samhain's autumnal aura caused temperatures to drop and turned leaves brown. With increased strength from other ghosts, Samhain could turn day into night.
