The xenomorph has seen many formsdue to its strange life-cycle as a parasite.

This is especially noticeable with side view shots of the creatures.

This design choice is intended since the xenomorph design wascreated by famous Swedish artist H.R.

Giger was known for his distinct bio-organic art style which heavily implemented sexual organs into alien-like designs.

This art style was also the inspiration for the aliens of theSpeciesfranchise.

They were slimmer and faster but imperfect precursors to the xenomorph.

This was how the neomorphs were able to bite limbs and even heads clean off.

Combined with their speed, it made them deadly opponents for the crew of the Covenant and even androids.

Six Fingers VS Four Fingers

Across theAlienmovies, xenomorphs actually have six fingers on each hand.

For the most part, thedesigns for the xenomorphs inAlien: Resurrectionremain consistent with those seen prior.

In James Cameron’sAliens- and several other films - the tails were upgraded.

Warrior drones feature tails with long spinal barbs and a massive stinger that allowed them to impale enemies.

That is if the xenomorphs even have genders, to begin with.

The only time a female is confirmed is with the queen.

To continue with the whole sexual theme, these practical effects were accomplished with KY jelly and condoms.

This wouldn’t be the first time this substance would be used.

The neon-green blood ofYautja Hunters in thePredatormovieswas made by mixing KY jelly with green glowsticks' fluid.

There are some other differences though: the Runner features a lack of tubes on its back.

On its rather long tail is easily the most massive and deadly bladed tip of all xenomorph types.

The strange thing is that the tail is what the Runner uses the least in combat.

Hardened Carapaces

Another difference between the originalAlienand its sequel is the aforementioned dome-like head.

In the firstAlien, the xenomorph sports a glossy and smooth cranium that fits into H.R.

It certainly gives an otherworldly appearance and helps the creature blend into the environment of the Nostromo.

Others suggest that it was simply just a new design choice to make the xenomorphs look creepy.

Human Skull

This is one that many could go their whole lives and not notice.

However, the dome was changed to the more opaque design everyone knows and loves.

The original suit with a human skull can be found in rare behind-the-scenes photos and in a museum.
