In honor of "Project Hail Mary"'s Rocky, we celebrate 17 sci-fi aliens who look nothing like humans

Split image showing three aliens that look nothing like humans (L-R) Starro the Conqueror from "The Suicide Squad", a Brain Bug from "Starship Troopers", and Kang (or Kodos?) from "The Simpsons".

Spend too long in the "Star Trek" — or indeed "Star Wars" universes — and you might start believing that every alien species is a human being with a few prosthetics glued to their faces. But while this approach certainly makes life easier for filmmakers, it doesn't quite live up to that old Vulcan maxim about "infinite diversity in infinite combinations".

So we reckon Mr Spock would approve of Rocky, Ryan Gosling's extra-terrestrial BFF in "Project Hail Mary", whose five limbs and complete lack of a face make him a rather more unconventional co-star.
