I'm glad for once I started a thread that didn't turn into a fight.
The reason I started this thread because when I did my second Aliens fan animated film, my #1 fan convinced me to introduce Alien crossbreeds. I had this awesome idea where Wey-Yu sic'ed Facehuggers on different animals based on the Kenner Aliens, but again, I stuck to the practical ones, in other words, animals that a Facehugger can get it's penis thing down. I got the Gorilla Alien, Snake Alien, Crab Alien (there are large crabs), Panther Alien, my version of the Dog Alien, a Boar Alien, a Rhino Alien, a Bull Alien (one with horns), and a Bat Alien. You ever heard of the largest bat, the flying fox, it's about the size of a dog, it's on the endangered species list, but still exists. I customized the models from Aliens video games like Colonial Marines and AVP2010. I thought it was fun. And of course, my 3rd story has the Ultramorph, because I felt that creature was a missed opportunity, I used a normal Alien with a Verdugo body from Resident Evil 4 because he had a smooth enough body.
