Superfacehugger

The Superfacehugger, sometimes called the Queen Facehugger, is a different type of Facehugger. The Superfacehugger has a black exoskeleton, (similar to the adult form of the Xenomorph,) a spiked tail, webbing in-between it's crablike legs, and it carries either one Queen embryo, or a Queen embryo and a normal Xenomorph embyro, (according to popular fan theories.) The Superfacehugger is seen only in the Special Edition of Alien3, and is often considered canon. Aside from those differences, the Superfacehugger is no different from the normal Facehugger.

In both releases of Alien3, two different organisms are infected with Xenomorph embryos, a dog (Or ox, in the Special Edition,) and Ripley. However, only one Facehugger is seen in the Theatrical Release version, and it does not explain how two creatures were infected. Also, the Facehugger is never mentioned afterwards. With the addition of the Superfacehugger in the Special Edition, it becomes somewhat less complicated, but the first Facehugger is never mentioned again. Some fans assume that the original Facehugger died in the crash, leaving only one Superfacehugger, and possibly, just one embryo. There are several theories regarding this, and they can be split into two groups with similar thoughts and ideas.

One group believes that there were two eggs on the ship, the first being the egg containing the Facehugger that caused the fire and impregenated the ox/dog, the second being the egg containing a Queen-bearing Superfacehugger; both eggs surviving the impact. Another theory is that the normal Facehugger injured itself trying to break into Ripley's cryotube, hence the acid blood causing a fire, and didn't survive, (the causes of death being the fire, the injury, and/or the ship's impact.) However, the Superfacehugger survived and it carries two embryos, one being a Queen, the other being a normal Xenomorph embryo.
