In early 2018, NECA released a 2-pack featuring figures of Batman and a ‘Joker’ Alien which are based on the old Batman/Aliens crossover comic book series.
Official Description
NECA is extremely excited to reveal the first in new series of action figure 2-packs inspired by classic comic book mash-ups! The first release in the “Versus” line comes from the 1997 Batman/Aliens comic book mini-series co-published by DC Comics and Dark Horse. In it, Batman faces strange new Aliens produced using DNA from some of Arkham Asylum’s deadliest inmates. The set includes two brand new, comic book based figures, both with over 30 points of articulation. Batman features a fabric cape, and the “Joker” Alien has a bendable tail.
