Across 2016 and 2017, Diamond Select Toys released three exclusive Ghostbusters Select figures of Ray, Peter and Winston covered in Marshmallow from the end of the 1984 movie. These were offered as exclusives in the main, and as single releases with no diorama pieces.
Now it has been confirmed that we will finally get a Marshmallow covered Egon to complete the set.
Infinite Earths broke the news that the new Egon was on its way and confirmed it would be a Previews exclusive available via comic book stores and independents. At present there is no release date.
"A Diamond Select Toys Release! The 1984 horror-comedy classic Ghostbusters is as beloved now as it ever was, and this action figure captures one of its most iconic moments! The most serious and strait-laced of the Ghostbusters, Egon Spengler gets covered with marshmallow in this 7-inch scale action figure inspired by the film's final scenes. This figure features newly sculpted parts and 16 points of articulation, plus alternate hands, proton pack, neutrino wand and display base. Sculpted by Gentle Giant!"
