What would the definitive Xenomorph look like?

MemberTrilobiteJuly 10, 2016In the seven movies of which it has made an appearance (not counting the skull in Predator 2) the Xenomorph has been shown to evolve and adapt by assimilating genetic traits from its various host's that prove beneficial to its survival. Using its first appearance in Alien as the archetype the deadly creature has since lost (and then regained) its carapace, gained (and then lost) scythe-like appendages on its forearms, evolved from an anatomical plantigrade posture to an anatomical digitigrade posture, lost (and then regained) its dorsal tubes and (mystery) dorsal appendage, evolved an ever-increasingly larger tip to its tail, and gradually lost the majority of the "mechanical" aspects of its skin, becoming more tainted with the flesh of its hosts with each new generation.
Recently Netherrealm Studios' latest Mortal Kombat game has reminded us of the Xenomorphs ability to assimilate features and traits from its hosts with the iconic characters inclusion in the games DLC, with the Xenomorph assimilating the trademark Tarkatan retractable blades on its forearms (pictured above). Of course, the once popular line of toys developed by Kenner explored many of the possibilities that the "genetic assimilation" could offer with many notorious traits included in their toy line-up, some of which are pictured in the collection below.
It is my belief that the best onscreen interpretations of the Xenomorph, to date, have been in the first two movies and the Deacons brief appearance in the closing moments of 2012's Prometheus. In my opinion, it was while ADI was in charge of the creature from Alien 3 up until AVP:R that the Xenomorph became with each iteration another step away from what made the creature so visually appealing, which was only made worse with the consistent requirement that ADI co-founder Tom Woodruff Jr. be inside the "hero" suit. Looking at Giger's drawings that inspired the Xenomorphs original design (such as "Necronomicon V", pictured below) I have always held that the Alien should be portrayed by a tall, slender woman in the suit rather than an average built man of average height. A feminine posture, stance, and gait would lend the Xenomorph a more fluid and nuanced performance's tenure. I also believe that the Xenomorphs head should be built around the actors head, not atop of it as I have always found the latter design lends the creature an unsightly thick neck.
While I may have my own ideas on what features I would like to see expressed in the "definitive" rendition of the Xenomorph, and with Alien: Covenant likely giving us a new generation of Xenomorph I am curious as to what elements of the creatures design other fans have preferred or would prefer to see. Should the Xenomorph have a Plantigrade or a Digitigrade stance? Should the original barb design for the tails tip return? Should the Carapace remain or not?
