This is a wonderfully detailed action figure by Bandai based on the alien Xenomorph as it appeared in the original Alien movie. It has been articulated in a way that replicates the poses that the Alien was seen in during the movie.
The tail alone contains 18 joints to allow for all sorts of posing. There are interchangable hands for even more combinations. And the head is actually translucent plastic showing off the brain underneath.
Although there are a lot of variations on the Xenomorph design these days I do think the original remains the best one. This would make a lovely addition to my ever growing toy collection.
