"It looks like damage."
The bio-helmet is one of the main tools used by the Yautja. As well as performing the basic function of protecting a Predator's head, the helmet also grants the wearer access to multiple vision modes including zoom capabilities, facilitates Vocal Mimicry, and includes breathing apparatus, diagnostics, and visual and audio recording systems. The helmet often also incorporates a red targeting laser used in conjunction with a Plasmacaster.
The bio-helmet is directly linked to a Predator's wrist gauntlet, which controls many of the helmet's functions. Together they form one of the most versatile tools used by the Predators, while the helmet itself is a distinctive aspect of their overall appearance.
Bio-helmets have been shown to have access to several different visual frequencies, is most commonly seen being infrared, effective to visualize the humans, but rendered essentially useless in a Xenomorph Hunt. Also available is a spectrum and a specifically tuned mode, EM field detector, used to visualize Xenomorphs. Additional vision modes are available to determine the health status of the targets. In Aliens vs. Predator: Requiem, a Yautja hunter gathers the substance he was containing a Facehugger in, and installed a new vision mode on his bio-helmet which allowed him to see the substance highlighted. He did this by inserting the substance via a needle into his wrist gauntlet, suggesting a connection between the two.
Housed within the helmet is a targeting and tracking system for shoulder based Plasmacasters. A shoulder mounted Plasmacaster uses this laser target designator, which comprises three corners of an open triangle, to aim at the designated prey. Incorporated to finalize the shot is a lock-on system. As the quarry is decided upon, the designator will zoom a triangle in on the prey which will flash and turn solid red, then fires. This also has a zoom capability, so the Predators can see and aim over great distances. This tracking system also allows the Predators to plot trajectories of thrown objects. The targeting system can also be used to heat up metals like Wristblades.
Another feature of the Predator's helmet is its voice translator/recorder. This device can both record and play strips of audio, which a Predator may use to express meaning or catch prey off guard, or to simply listen to the voices of their prey, as if to study their language. The helmet also seems to affect hearing as well; in Predator, when the Predator took its helmet off, it heard things at a much higher pitch than before and slightly more distorted. As seen in Aliens vs. Predator: Requiem, the helmet also has a video playback mode that displays what the wearer has witnessed or been involved in.
In the Aliens versus Predator video games, the Predator has four vision modes, regular vision (to fit in with the first-person shooter genre), thermal (spotting regular beings like humans), electric (gives a red background, used spotting Xenomorph's by their white outline), and Predator vision (gives a green background, used for spotting other Predators and technological objects, such as weapons and armor, shown in a white outline). The Predator vision mode can also be used for orientation in pitch-dark areas, as it displays a clear, light-independent picture of terrain.
However, in Aliens vs. Predator, there are only three Predator vision modes: Normal, Thermal/Heat, and Xenomorph. Normal mode is self-explanatory. Thermal vision is used to detect human and synthetics (and Predators — cloaked and uncloaked — in death matches). Alien vision is to detect Xenomorphs. Humans, Synthetics, and Predators (especially cloaked ones) are nearly invisible in Alien mode, whereas Xenomorphs are nearly invisible in Heat mode, because they do not give off a thermal signature.
In Predator: Concrete Jungle, the Predator's helmet offered four types of vision and varying diagnostic functions for each: Normal Vision, which was the same as a human and had no diagnostic; Thermal Vision, which highlighted heat signatures and could analyze health and armor weaknesses in prey. Although in this game it could also highlight Xenomorphs even though in the movies and games they are not seen in Thermal; Tech vision, which contrasted energy sources and analyzed a prey's weapon systems; and Neuro Vision, which exposed the prey's current emotional status (calm, panicking, hostile, etc.) and, on scan, would show the target's affiliation and rank.
There have been numerous bio-helmet designs and variations shown over the Predator franchise and most Yautja have unique helmets and that appear to be personalized to some degree. These design variations appear to be entirely cosmetic.
Jungle Hunter's bio-helmet: This was the first bio-helmet ever seen, as well as the most basic in design. It was a simple, yet effective helmet.
City Hunter's bio-helmet: This bio-helmet was similar to the original one, but with a few major differences. The helmet's shape is noticeably different, with a steeper forehead and a full-rounded crest, along with a more prominent snout. Rather than two eye holes, it bears a single visor. The helmet was also a deep bronze colour.
Chopper's bio-helmet: This bio-helmet had gill-like patterns on both side of its mouth area, as well as a single visor and a dull copper colouration. Due to its unique design, Chopper has earned the name "Gill".
Celtic's bio-helmet: This bio-helmet had a strange, elaborate design around the mouth area, making it appear vaguely like a Yautja's face. The helmet also shows four scratch marks over the left eye when Celtic got scratched by the Xenomorph Grid.
Scar's bio-helmet: This bio-helmet was in many ways identical to the Jungle Hunter's helmet, although it had a Predator-type visor. When Scar kills a Xenomorph, he burns a mark onto the forehead, making him as a Blooded Yautja.
Wolf's bio-helmet: This bio-helmet bore several marks on the face, lines of Yautja script over the forehead, a reptilian hide complete with spikes, and a deep gunmetal colouration. Compared to many other Predators' helmet, Wolf's helmet takes on a slightly more skeletal appearance, with more pronounced cheeks, brow and snout.
Tracker's bio-helmet: This bio-helmet appears vaguely similar to a regular helmet with two tusks tied to the snout, a darker colouration with a hint of green, and a slightly more organic appearance.
Falconer's bio-helmet : This bio-helmet is somewhat bulkier than most others. It had lines on both sides of the mouth area, and also featured two metal spikes on the back. It slightly resembles a real life falcon head.
Berserker's bio-helmet: Compared to the typical design of the helmet, the Berserker Predator's bio-helmet was more narrow with a very dark umber colouration, and features deep red visors. Its distinguishing feature is a large jawbone attached to the bottom half of the helmet.
Crucified Predator's bio-helmet: This bio-helmet is similar to the original one used by the Jungle Hunter, but has heavy damage on the left side and exposes the Crucified Predator's left eye.
Fugitive Predator's bio-helmet: This bio-helmet resembles the Jungle Hunter's helmet, but features a sort of metallic shine to it and a prominent, flat mouthpiece. Unlike previous bio-helmets, this one features a large scratch across the left eye and has a Plasmacaster hidden inside it.
Serpent bio-helmet: This helmet appears to be styled to represent the face of the Xenomorphs. The forehead is smooth, representative of the Alien's carapace, and the mouth area is shaped like the fanged maw of the Alien. It also features a split crest at the top.
Spartan's bio-helmet: This helmet is shaped like a Spartan helmet. It has somewhat of an opening near the mouth and has two visors, similar in design to a real Spartan helmet's. It is also split into three sections at the top of the head.
Elder Predator bio-helmet: This helmet is a lot different than other bio-helmets. It features an opening near the mouth area, and the top of the helmet is adorned with many markings, representative of all of the battles and hunts the Predator has experienced.
Ancient Predator (Bull) bio-helmet: This helmet is somewhat similar in shape to the original helmet, with the exception of the cybernetic details on the cheek areas. The Ancient Predator's personalized helmet bears a bronze coloration, as well as special Yautja inscriptions on the brow and a large opening on the front of the snout.
Big Red's bio-helmet: This helmet appears in the fan film Batman: Dead End. After Batman defeats the Predator, the rest of his hunting party appears, led by Big Red. The helmet he wears is almost the same as the Classic helmet, aside from its bright red coloration and the black streaks that adorn the forehead.
Scarface's bio-helmet: This helmet appears in the 2005 video game Predator: Concrete Jungle. It bears a striking resemblance to Celtic's bio-helmet, with the only real difference between the two being that Scarface's bio-helmet features a row of pointed spikes that run down the center of the helmet and a red line going down the left eye hole.
Ronald Noland's bio-helmet: A helmet presumably taken from a Predator he killed, Nolan -- a human -- had a bio-helmet that he used to hunt down the main characters of Predators. Despite being made for a Yautja, Nolan seems to have no trouble using the helmet. The helmet was actually broken and fixed to another helmet, one that looks similar to a samurai's helmet.
Machiko Noguchi's bio-helmet: Machiko's bio-helmet was created to be unique compared to typical bio-helmets as it was made to fit her face and head. It lacks the protruding "muzzle" of a typical helmet, and like a human face, is mostly flat as it does not need to account for Mandibles. The eye pieces are also more transparent as her eyes can be seen through it.
Aliens vs. Predator bio-helmet: This helmet appears in the 2010 video game Aliens vs. Predator and is worn by the Elite Clan students, as well as Dark himself. It bears a resemblance to the one that was worn by the Jungle Hunter. This helmet, however, is somewhat sharper in shape (featuring more pronounced cheeks and a flatter snout), has a row of vertical patterns on each cheek and is darker than the other helmets, sporting a gunmetal coloration.
The Predators use an infrared vision made in their helmets as their primary source of vision. This gives the Predator a thermal imagining sensory where they use it to track, survey, and target their prey. However, in the original theatrical release Predator, this can be skewed by the prey when Alan "Dutch" Schaefer becomes covered in mud, which covers his heat image, thus allowing him to hide not but a few feet away from the Predator. Dutch realizes this and uses it to work to his advantage later in the final battle.
Predators also employ an ultraviolet vision mode, as seen in Predator 2. However, it is shown that during this scene we see the City Hunter employ several different modes of vision before settling on one. Not all of these vision modes are known.
During the theatrical release of Alien vs. Predator, we also see that the Predators have what seems to be a finely tuned EM Field Generator, which is used to see and hunt Xenomorphs, since infrared is seemingly useless because Xenomorphs don't give off any heat, and acid doesn't generate heat. In this vision mode we see the Xenomorphs as a green outlined figure, more or less.
In Predator: Concrete Jungle, apart from the thermal vision, there is a vision which shows electrical currents and a neural vision which shows the mood of the Predator's prey, allowing the Predator to tell the difference from passive civilians and aggressive enemies.
Aliens versus Predator 2 introduces a new vision mode called 'PredTech', which essentially inverses all colors (also allowing the Predator to see in the dark, much like the Alien's alternate vision) and makes organic material seem transparant. Artificial objects such as firearms and Sentry Guns stand out in PredTech, which also shows cloaked Predators (which do not show up on infra-red or EM vision).
In Aliens Vs Predator: Deadliest of the Species, the helmet are shown also as working as a life support system, allowing the Yautja to breath easily on any world, (The Yautjas can also breath on human worlds, but have more difficulty, having to breath deeper.) It also featured a modified version allowing a human to breath in a natural Yautja environment, which would normally burn the lungs of and kill any human. Though this conflicts with Predator 2, where a human walked around unaided in a Yautja ship without being harmed at all. In the first Predator film the helmet was originally designed to look like a mechanized version of the creature's face. The prop was scrapped, as it was felt that it gave away the Predator's final appearance too early. The original design would reappear in subsequent films as the helmets of background or secondary Predator characters. In Aliens vs. Predator: Requiem, concept artist drew the helmet of the Wolf Predator as being made from a trophy skull, while drew the helmet as identical to that appearing in Predator 2, with the addition of a spiked reptilian hide strapped to it.
In Predators, it seems to show that Predator helmets are capable of withstanding incredible damage. It can even withstand bullets as shown when Ricky tries to kill Wolf by shooting him in the face. The Crucified Predator seems to have had part of his helmet blown off by from the blast mark of presumably a Plasmacaster more than likely Mr. Black's before the events of the movie, as it seems to be functional when Classic puts his back on. Also, in Aliens vs. Predator: Requiem, Wolf manages to gain knowledge of the Predalien through the helmet which seems to have had the top stabbed through. This may also mean that Celtic's helmet, while punctured, if been recovered, may have very well worked. Although this can also mean that most of the technology to work the helmet is in the mouth area which makes sense as the others are still functioning and with battle scars to the forehead or face.
A Yautja's bio-helmet has the ability to flash its eye area, turning them usually bright yellow. In Predator, the Jungle Hunter does this while he's staring at Mac. In Aliens vs. Predator, as Rookie in the jungle mission, after you find the skinned body, you can just notice a Yautja walking past you while flashing its eyes. This happens again in the Alien mission (The Ruins) where you fight the Predators, but the Predators' eyes flash bright green, not yellow. Wolf also flashes his eyes blue. This is most likely customization by the Predators. They could possibly use this visor-flashing ability for frightening or intimidating their prey to make them run. This would make their quarry easier to kill as said by Royce that if you run, you die. It is also possible that Predators do not flash their eyes intentionally, but it is rather a side-effect of the Cloak. Since the field bends light around the Predator, the Predator would not be able to see, since visible light, and thus potentially infrared light, would be bent around the Predator's eyes, preventing it from reaching them. The area around the eyes may have a "weakened" light-bending field or some other mechanism to allow light to reach the Predator's eyes, resulting in the eye lenses of the helmet seeming to "flash" at certain times or angles.
