Yes, I recognize that these Xenomorphs from Aliens are not minifigures, but who else is your ABS Ripley going to fight? These are some great creations from Brandon (AKA Catsy), with lots of articulation and pose-ability.
These would pair nicely with the upcoming Hazel Fantasy Aliens line which debuts at the Tokyo Toy Fair in March.
Brandon has incorporated these great builds into a series of scenes which can be seen on his Flickr stream.
