Wikipedia:Articles for deletion/List of Alien morphs in the Alien franchise
The actual overview of the creatures, which is the only sourced content here, is already fully covered at Alien (creature in Alien franchise).  Those sources also appear to be largely primary or from unreliable sources, so I don't really see anything that would need to be merged to the primary article.  The actual list portion is a lot of unsourced, overly detailed plot information that does not pass
