Acid Rain Astronauts/Spacemen were first introduced through Kit Lau's Instagram story update "A Prisoner Without Fetter" on 15/11/2016.
A few days later first glimpses of the prototype figures were viewed. There appears to be 2 seperate types of Spacemen, a white version and black, it is unknown whether these will reflect on the final colourschemes. The figures currently have no known accessories and boast impressive articulation.
The allegiances of the Spacemen are currently unknown, given there are 2 types this could suggest either opposing nations/factions or 2 BABEL units for different use.
