|The 23rd series of Spawn action figures features five intricate new designs based on the thoughts and sketches of well-known Spawn comic book artist Greg Capullo: Spawn, Angel, Al Simmons, Malebolgia, and Kin. One pivotal event in the Hellspawn mythos is Spawn's slaying of his master, Malebolgia. But what if this event had gone differently? What if Malebolgia did not die? This premise is the inspiration for Spawn Series 23: Mutations, which reveals a twisted vision of the Spawn world that could have been.
