. Dan O'Bannon drafted an opening in which the crew of a mining ship are sent to investigate a mysterious message on an alien planet. He eventually settled on the threat being an alien creature; however, he could not conceive of an interesting way for it to get onto the ship. Inspired after waking from a dream, Shusett said, "I have an idea: the monster screws one of them," planting its seed in his body, and then bursting out of his chest. Both realized the idea had never been done before, and it subsequently became the core of the film. "This is a movie about alien interspecies rape," O'Bannon said on the documentary Alien Evolution, "That's scary because it hits all of our buttons." O'Bannon felt that the symbolism of "homosexual oral rape" was an effective means of discomforting male viewers.

The title of the film was decided late in the script's development. O'Bannon had quickly dropped the film's original title, Star Beast, but could not think of a name to replace it. "I was running through titles, and they all stank", O'Bannon said in an interview, "when suddenly, that word alien just came out of the typewriter at me. Alien. It's a noun and it's an adjective." The word alien subsequently became the title of the film and, by extension, the name of the creature itself.

Prior to writing the script to Alien, O'Bannon had been working in France for Chilean cult director Alejandro Jodorowsky

. Giger showed O'Bannon his nightmarish, monochromatic artwork, which left O'Bannon deeply disturbed. "I had never seen anything that was quite as horrible and at the same time as beautiful as his work," he remembered later. The Dune film collapsed, but O'Bannon would remember Giger when Alien was greenlit, and suggested to director Ridley Scott

, Scott immediately saw the potential for Giger's designs, and chose Necronom IV, a painting Giger completed in 1976, as the basis for the Alien's design, citing its beauty and strong sexual overtones. That the creature could just as easily have been male or female was also a strong factor in the decision to use it. "It could just as easily fuck you before it killed you", said line producer Ivor Powell, "[which] made it all the more disconcerting." Fox was initially wary of allowing Giger onto the project, saying that his works would be too disturbing for audiences, but eventually relented. Giger initially offered to completely design the Alien from scratch, but Scott mandated that he base his work on Necronom IV, saying that to start over from the beginning would be too time-consuming. Giger signed on to design the adult, egg and chest-burster forms, but ultimately also designed the alien planetoid LV-426 and the Space Jockey alien vessel.

Giger conceived the Alien as being vaguely human but a human in full armor, protected from all outside forces. He mandated that the creature have no eyes, because he felt that it made them much more frightening if you could not tell they were looking at you. Giger also gave the Alien's mouth a second inner set of Pharyngeal jaws

Scott decided on the man-in-suit approach for creating the creature onscreen. Initially circus performers were tried, then multiple actors together in the same costume, but neither proved scary.

This creature has no specific name, and has been referred to most often onscreen, and in the credits of each film, simply as the Alien.

Aliens do not radiate heat, as their body heat matches the ambient temperature of the environment in which they are found. In most of the films, adult Aliens have the ability of running and crawling along ceilings and walls. They have great physical strength, having been shown to be capable of breaking through welded steel doors.

s. The sharp tip was initially a small, scorpion-like barb, but from Aliens onwards the blade design increased in size and changed in appearance to more closely resemble a slashing weapon. From Alien Resurrection onwards, the tails have a flat ridge of spines at the base of the blade. This was introduced to help them swim convincingly, and was left intact in the subsequent cross-overs. The original shooting script for Aliens and the novelization both featured a scene in which Lieutenant Gorman is "stung" by the barb tail and rendered unconscious. In the final cut of the movie, Gorman is knocked out by falling crates. As a weapon, the strength of the tail is very effective, having been shown to be strong enough to impale and lift a Predator with seemingly little effort.

 was used to illustrate the Alien's point of view. In the novelization of the movie Alien, the creature is held mesmerized by a spinning green light for several minutes. In Aliens, the adult creatures have a more textured head rather than a smooth carapace. In the commentary for Aliens, it was speculated that this was part of the maturation of the creatures, as they had been alive far longer than the original Alien. The smooth design of the carapace would be used again in Alien 3 and Alien Resurrection, although made narrower with a longer muzzle and more prominent chin. This design would be kept in Alien versus Predator, and abandoned in Aliens vs. Predator: Requiem in favor of the ribbed design. The Aliens' inner jaws are powerful enough to smash through bone and metal.

Throughout their appearances, human-spawned Aliens have been shown to have a fluctuating number of fingers

. In Alien, the creature has webbed, six fingered hands. In Aliens, the number of fingers is reduced to three (two "paired" and a single, opposable thumb), and they are shown to be much longer and more skeletal. In Alien Resurrection, the number of digits is increased to four, with two long middle fingers and a pair of thumbs. This design is kept in the Alien vs. Predator films, though the hands were made bulkier in order to make the Aliens seem more formidable against the Predators.

Aliens have been alternately portrayed as both plantigrade

 organisms, usually in accordance to their host. Human-spawned Aliens were usually portrayed as having humanoid hind limbs, while in Alien 3, the featured Alien sported double-jointed legs due to its quadrupedal host. This characteristic would be continued in Alien Resurrection for the human-spawned Aliens. Tom Woodruff, who had previously played the "dog-alien" in Alien 3, described the human-spawned Aliens in Resurrection as feeling more like a dog than the previous creature, despite having been born from human hosts. The human spawned Alien warriors would revert back to a plantigrade posture in Alien vs. Predator.

Blood and secretions

Alien blood is an extremely potent acid
Acid

 and is capable of corroding on contact almost any substance with alarming speed. It is dull yellowish-green in color, and seems to be pressurized inside the body so that it spurts out when punctured. Shusett suggested the idea that the creature have acid blood as a plausible means to make the creature "unkillable"; if one were to use traditional firearms or explosives to attack it, its blood would eat through the hull of the ship. The Alien novelization suggests that, at least at the "facehugger" stage, the acid is not blood but a fluid maintained under pressure between a double layer of skin. In later films in the series, the Aliens are shown to be conscious of the effects of their acidic blood, and even use it to their advantage: In Alien Resurrection, two Aliens escape a cage by killing a fellow Alien so its acid eats through the cage floor; in Aliens vs. Predator a queen being held by chains apparently instructs several Aliens to slash and cut her, thus corroding the chains.
In the Aliens vs. Predator: Requiem documentary: "Science of the Alien", it is theorized that the Aliens' acid blood could be some type of "hydrosulphuric acid" composition due to its corrosiveness and the conspicuously toxic effects on living human tissue. The documentary also speculates that Aliens are immune to their own acidic and toxic liquids due to a endobiological build-up similar to the human stomach's ability to protect itself from its digestive fluids. The documentary takes this theory one step further and speculates that the Alien organisms' protection system against its own toxic hydrosulphuric acid is protecting the rest of the organism with what is basically a bio-organically produced Teflon isolation.

. In both cases, the Aliens managed to learn how to operate the machinery of their mechanized environments at a very basic level. On LV-426, the Aliens were able to cut the power from a section of the complex to allow themselves access to the humans. The queen figured out to board the elevator simply by observing Ripley and Newt escaping in the one beside it, as Ripley had called for both elevators and boarded the first one to arrive. The novelisation of the film notes that the queen establishing her 'nest' at the base's main power plant could equally be the result of her selecting the warmest part of the base to make her nest or her deliberately selecting a location where any attackers would be unable to destroy her without destroying the entire facility. In the director's commentary for Aliens, James Cameron noted that the creatures in Aliens had been alive for far longer than the Alien in the original, and so had more time to learn how to manipulate machinery. On the USM Auriga, they were able to use blood from another Alien to melt through their enclosure and escape, with the Aliens in the Antarctic temple using a similar strategy to free the queen from her chains. With the exception of the "Newborn", Aliens have demonstrated little actual emotion, save for self preservation

Queen

Queen Aliens are significantly larger and stronger than the warriors, approximately 4.5 metres (14.8 ft) tall. Their body structure differs also, having two pairs of arms, one large and one small. The queen's head is larger than other adult Aliens and is protected by a large, flat crest, like a crown, and they vary from queen-to-queen. Unlike other Aliens, the queen also has high heel protrusions from its feet.

Alien vs. Predator is a 2004 American science fiction film directed by Paul W. S. Anderson for 20th Century Fox and starring Sanaa Lathan and Lance Henriksen. The film adapts the Alien vs. Predator crossover imprint bringing together the eponymous creatures of the Alien and Predator series, a...

the queen's basic design was altered to make it more "streamlined" in appearance and its over-all size was increased to 6 meters (20 feet) tall. Other changes include the removal of the "high-heel" protrusions on its legs, including additional spines on its head and making its waist thinner because there was no need for puppeteers inside its chest. The animatronic laying queen had 47 points of hydraulic motion.

Aliens vs. Predator: Requiem (2007) introduced a younger form of the full grown queen, albeit with traits inherited from its Predator host. Recalling the facehugger's method of embryo implantation, the Predalien uses its inner mouth to directly deposit multiple chestburster embryos into pregnant female hosts. This is explained by the Brothers Strause as a means of quickly building an army of Aliens before the young queen evolves into its sedentary, egg-laying state.

Egg

The eggs laid by the queen are large, ellipsoidal leathery objects between two to three feet high with a four-lobed opening at the top. As a potential host approaches, the egg's lobes unfold like flower petals, and the parasitic facehugger extracts itself from the egg and attaches itself to the potential host. Giger initially designed the eggs with a much more obviously vaginal appearance, complete with an "inner and outer vulva". The producers complained that Catholic countries would ban the film if the allusion was too strong, so Giger doubled the lobes to four, so that, in his words, "seen from above, they would form the cross that people in Catholic countries are so fond of looking at." The interior of the original egg was composed of "Nottingham lace", which is the lining of a cow's stomach. In the first film, the quick shot of the facehugger erupting from the egg was done with sheep's intestine. Initially the egg remained totally stationary save for the hydraulic movement of the lobes; however, by Alien Resurrection the entire egg was made to ripple as it opened.

Facehugger

A facehugger is the second stage in the Alien's life cycle. It has eight long finger-like legs which allow it to crawl rapidly, and a long tail adapted for making great leaps. These particular appendages give it an appearance somewhat comparable to chelicerate

; its only purpose is to make contact with the host's mouth for the implantation process, by gripping its legs around the victim's head and wrapping its tail around the host's neck. Upon making contact, the facehugger tightens its tail around the host's neck in order to render it unconscious through oxygen deprivation. The facehugger then inserts a proboscis

 down the host's throat, supplying it with oxygen while simultaneously implanting an embryo. Attempts to remove facehuggers generally prove fatal, as the parasitoid will respond by tightening its grip, and the facehugger's acidic blood prevents it from being safely cut away.

Once the Alien embryo is safely implanted, the facehugger detaches and dies.

Giger's original design for the facehugger was a much larger creature with eyes and a spring-loaded tail. Later, in response to comments from the filmmakers, Giger reduced the creature's size substantially. At first Giger assumed that the facehugger would wrap around the outside of the astronaut's helmet, but Scott decided that it would have far more impact if the facehugger were revealed once the helmet was removed. Scott and Giger realised that the facehugger could burn through the helmet's faceplate with its acid blood; subsequent redesigns of the space helmet included a far larger faceplate to allow for this.

 sculpture of the facehugger was produced, O'Bannon asked that it should remain unpainted, believing the rubber, which resembled human skin, was more plausible.

In Alien 3, another addition, a "super-facehugger" that would carry the embryo of the queen Alien, was planned but ultimately dropped. The super-facehugger is briefly glimpsed in the Assembly cut of Alien 3, but not identified as such.

Chestburster

After implantation, facehuggers die and the embryo's host wakes up afterwards showing no considerable outward negative symptoms. Symptoms build acutely after detachment of the facehugger, the most common being sore throat, slight nausea

 is extended in preparation of a queen birth, symptoms will include a shortness of breath, exhaustion, and hemorrhaging (detectable through biological scanners and present in nosebleeds or other seemingly random bleeding incidents), as well as chest pains inflicted either in lack of chest space due to the chestburster's presence, or even premature attempts to escape the host.

 and other body structure changes. Over the course of 1–24 hours, indeterminable in some cases, and sometimes up to a week, in the case of some queens, the embryo develops into a chestburster, at which point it emerges, violently ripping open the chest of the host, killing it.

 and constructed by special effects artist Roger Dicken. Giger had produced a model of a chestburster that resembled a "degenerate plucked turkey" and was far too large to fit inside a ribcage. Much to Giger's chagrin, his model reduced the production team to fits of laughter on sight. Scott drafted a series of alternative designs for the chestburster based on the philosophy of working "back [from the adult] to the child" and ultimately produced "something phallic." The chestburster in the original Alien was armless but arms were added in Aliens to facilitate the creature crawling its way out of its host's corpse. This concept would be abandoned in Alien Resurrection and subsequent films.

Growth and maturity

When a chestburster erupts from the body of its host, it is less than 1 feet (30.5 cm) tall. However, it soon undergoes a dramatic growth spurt, reaching adult size in a matter of hours; in Alien the chestburster had grown to 2 metres (6.6 ft) in height by the time the Nostromo crew located it again. The chestburster is shown to have molted before reaching maturity. In Aliens vs. Predator: Requiem Alien warriors are shown who are still growing, showing shedding skin. In the unrated cut, the Predalien is shown actively wiping off its final molted skin at the film's start. A shed skin of a growing chestburster is also shown, showing that the creature's final limbs do not grow in the earliest stages.

Alternative forms

Aliens take on various forms depending on the characteristics of their hosts. Most of the Aliens seen to date have been human-spawned, but a number of Aliens born from other hosts have also been seen.

"Dog Alien"

The "Dog Alien" (also jokingly referred to as the "Bambi burster", or "Runner Alien" in the expanded universe stories), was introduced in Alien 3. The creature itself shares the same basic physical conformation and instincts as the other Aliens shown in the previous films, although there are several differences due to the host it was spawned from (a dog in the theatrical cut, an ox

, and was asked to redesign his own creations for Alien 3. Giger's new designs included an aquatic face-hugger and a four-legged version of the adult Alien.

." However, when Tom Woodruff and Alec Gillis of Amalgamated Dynamics told Giger that they had their own design, Giger expressed himself as "very upset" and that the creature he had especially designed was his "baby". Even after the production severed contact, Giger continued to fax suggestions to Fincher because of his enthusiasm for the project, and made full-scale drawings and a sculpt of the Alien, all of which were rejected.
Giger would later be angered by the end credits of the released film presenting him as merely the creator of the original creature, and the fact that ADI personnel gave a series of interviews that minimized Giger's contribution. Fox eventually reimbursed Giger, but only after he refused to be interviewed for their behind-the-scenes documentary of Alien 3.

The Academy Awards overlooked Giger's contribution to Alien 3. However, Ridley Scott included Giger's name along with nominees Carlo Rambaldi and Richard Johnson. Fox, at the time Alien 3 was released, pointed out that studios are precluded from submitting nominees in the effects category directly to the Academy. This upset Giger so much that at one point he sent Academy president Karl Malden a fax with this closing comment: "I am under the strong impression that my contribution to the visual effects of the nominated movie has been intentionally suppressed", signing the letter with a large black pentagram

.

Giger however would comment that he thought the resulting film was "okay" and that the Alien was "better than in the second film."

Newborn

In Alien Resurrection, due to significant genetic tampering in an attempt to recover DNA from the deceased Ellen Ripley and the Alien Queen within her, the resulting cloned Aliens show a number of minor human traits. The cloned Queen inherits a womb, and as a result it ceases to lay eggs and gives birth to a humanoid mutant. Physically, the human-Alien Newborn is very different from its brethren, being larger, with pale, translucent skin, a skull-shaped face with eyes, a human tongue and complete absence of a tail. The Newborn fails to bond with its Alien Queen mother, and kills it. Instead, the Newborn sees the Ripley clone as a surrogate parent.

These pincers would have been used to immobilise its prey as it drained it of blood through the inner jaw. The creature was also meant to rival the Queen in size.

 later asked ADI to lean towards making the human-Alien hybrid, known as the Newborn, more human than Alien. The Newborn's eyes and nose were added to improve its expressions to make it a character, rather than just a "killing machine", and give it depth as a character. Jeunet was adamant about the Newborn having genitalia, a mix of both sexes. However, Fox was uncomfortable and even Jeunet felt "even for a Frenchman, it's too much."

s, skin color and similar vocalizations. It is a large, bulky creature, and possesses physical strength greater than that of human-spawned Aliens. Like human-born Aliens, it is also shown to be stronger than its host species, as evidenced by its ability to pin, push, and knock a Predator away with ease. It also possessed the ability to impregnate human hosts with multiple Alien embryos.
