TRANSLUCENT-MORPH

Maybe they could Discover this New Kind of Xenomorph at the Bottom of a Ocean, maybe on some other World?

James Cameron would love this angle! Might bring him back to the franchise ( for good or bad lol )

Art is so incredibly important to the Alien series. What Giger brought to franchise can never be overstated. The series might as well be called Giger's Alien. And I've yet to see anything close to the genius of Giger.

Star Wars, Star Trek, etc.. just aren't that reliant on it. I can't think of a creature from any of them that was breathtaking.....maybe the the summa-verminoth from Han Solo?

I wonder if they can even make creatures similar to Giger? How does the Giger estate work?

I think the Giger Estate does have a BIG SAY in WHAT they can or CANT do in Terms of when Designing anything related to his Bio-Mechanical Aesthetic.

But i think when you are looking at Introducing other New Monsters then you DONT have to make them Close to that Aesthetic we saw in ALIEN... The Deacon and Neomorph while we could see some Connection, they was BOTH nothing like the Bio-Mechanical Fiend from the FIRST MOVIE.

This for Example from ALIENS: Fireteam Elite...........

We also have Various Concept Work from the Prequels that do-not have that Bio-Mechanical Aesthetic like we had with the Xenomorph.  So i think if you introduce a New Monster that has some of that Aesthetic then YES i think maybe they would have to get Permission  from the Giger Estate.

For Example like the Unused Ultramorph Concept..... because maybe its LIKENESS is too Close to HR Gigers Designs.

That could have been interesting.

From what I'm aware, anything Giger made for the alien series (Some xenomorph designs, derelict design, derelict interior, egg silo, facehugger victims etc) belongs to studio, so concept artists can work from that. Anything else that Giger made in his spare time (all those bio mechanical landscapes and abominations) for galleries or whatever belongs to his estate and would have to be negotiated and approved for use with the estate.

Looking at some of the early Alien covenant concept art by Khang Lee, there were lots of interesting semi-translucent alien creatures that seemed to be inspired by aquatic life forms.

Like Guillermo Del Toro said, when designing a movie monster, reference nature.

Well the Source i had from Feb 2015 (taken from Information about October 2014) had Claimed that there would be TWO MONSTERS in the Prometheus Sequel and had indicated that ONE was kind of Translucent........... The Neomorph (Especially the Infant Burster Stage was kind of Translucent a Bit.....) but it would be NICE to see something much more Translucent maybe NOT quite as much as a Jelly Fish though.
