Deathclaw

Deathclaws are an enormously large, agile, and strong species of mutant reptiles created through genetic engineering. They are substantially larger than a human, and have large and dangerous claws.

Female deathclaws, also called Mothers and Matriarchs, are stronger and tougher than males, as well as fewer in numbers. Only one female is the pack mother at a given time, with another female taking its place when it dies. A pack is led by an 'alpha male'. Although they do not have vocal chords, the deathclaws seem to be able mimic human speech much the same as a parrot does, although normal deathclaws aren't intelligent enough to be capable of real speech.

History
The deathclaws were originally created before the Great War by the United States military, in order to replace humans during high-risk close-combat search-and-destroy missions. They were Jackson's Chameleons genetically modified with DNA of various other species.

The Master also experimented on the deathclaws early on, but his experiments were not very successful, and eventually they were not used in his army. However, some of the modifications he made to their genome refined them into even more dangerous beasts.

Around 2161, deathclaws were still a mystery, a legendary creature, to many inhabitants of Southern California. In Fallout, a deathclaw first appeared in a mission to find missing caravans: while the deathclaw was not responsible for the caravan disappearances, as some had believed, evidence in its lair did lead to the correct solution. Deathclaws had also established a nest in the abandoned warehouse district of the Boneyard, obstructing traffic between the Gun Runners and potential trading partners and making any scavenging in the area very hazardous. As the deathclaw population grew, the deathclaws stopped being perceived as legendary beasts, and started to be seen as simply yet another dangerous animal.

Varieties
Outside of the two versions described below, there are at least two variations of the 'regular' deathclaw. One has a spiked back and long, forward horns, while the other has no spikes on the back and has smaller, backward horns. It is possible that the former deathclaws are male while the latter are female or the other way around.

Talking deathclaws
In 2235, the Enclave captured many deathclaws and exposed them to FEV. This boosted their intelligence, giving them the ability to talk with varying degrees of erudition and articulation. This subspecies was highly intelligent, about the equivalent of an eight-year-old, with some individuals reaching human normal level. Their learning capacity was very high and they were capable of abstract thought and reasoning. Although they did not have vocal chords, the deathclaws seemed to mimic human speech the same as a parrot does. Socially, they had rigidly hierarchical, peaceful, pack-based ethical code. They were extremely loyal to the pack as a whole, treating it as a family unit rather than having individual families. Fights within a pack are unheard of, and the pack's leader controls many aspects of life, such as choosing and matching female and male deathclaws for reproduction. Oddly enough, Deathclaws are not subject to sterility from FEV exposure. Why this is was never explored.

While the Enclave hoped that the Deathclaws would be intelligent enough to obey orders without being so intelligent as to question them, the Enclave's deathclaws began to doubt the morality of their masters. While they helped the Enclave in storming Vault 13 in 2242 and kidnapping the population, they later abandoned the Enclave, adopting the now-empty vault as their new home under the leadership of Gruthar.

Several humans from the surrounding area moved into the vault to live under the protection of the deathclaws, but not all were pleased with these new neighbors. One human, Matt, struck against the deathclaws by bombing the mother and hatchlings (the deathclaw mother survived, but security was tightened from then on). The deathclaws faced other problems adapting to life in the vault, as well: after the overthrow of the paranoid Overseer, the dwellers of Vault 13 had turned day-to-day operations of the vault over to a Brotherhood-technology based computer. The only way the deathclaws could interact with it was by voice commands, but the computer's voice module was broken. Fortunately, a travelling tribal known as the Chosen One had a replacement voice module, and was willing to install his in exchange for Gruthar's help in finding a GECK, one of which Gruthar had within the vault's storage area.

The deathclaws paid a high price for their rebellion, however: an Enclave team, lead by Frank Horrigan, attacked Vault 13 and massacred the deathclaws (and presumably those humans under their protection). Of Vault 13's inhabitants, only Goris, who had accompanied the Chosen One on adventures outside Vault 13, survived.

Depending on the actions of the Chosen One, Xarn, a deathclaw kept in Navarro under the custody of Doctor Schreber, and Goris were the only intelligent deathclaws in the whole Fallout Canon to survive the end of Fallout 2. According to some reports, they did not, however, reproduce, and were the last of their kind. Whether this will hold true in the future remains to be seen.

Hairy deathclaws
A deathclaw subspecies living in the area of the former states of Illinois, Missouri and Kansas developed patches of fur to better cope with the colder climate. Furthermore, some of them were noted to be capable of speech as early as in 2197, which means that they either developed speech through spontaneous mutation, or were experimented on by someone other than the Enclave. They were also more matriarchal than their Western counterparts, with packs being led by Matriarchs.

One such Matriarch was captured by the psychic tribe known as the Beastlords. While the tribals were able to use their psychic powers to control lesser animals, the deathclaws were intelligent enough to resist them. However, they cooperated with the Beastlords in order to protect their Mother. After the Matriarch was freed by the Midwestern Brotherhood of Steel, that pack decided to join the Brotherhood, and the Elders surprisingly agreed.

Strategy for Fallout 3
Deathclaws are bad news in Fallout 3. They are pretty much the meanest monster in the game. Taking down a Deathclaw requires heavy preparation. It is highly discouraged to use Melee or Unarmed weapons to take one down, and at minimum you should use from mid to high-powered Small Guns up to take one down, maybe coupled with some explosives for good measure. Ideally, you should try to get a sneak critical on one before you actually start fighting. Your main priority should be to cripple their legs from afar, so that they can't run after you or pounce. Big Guns are strongly recommended against them; the Minigun, in particular, is a good choice, since it has a great rate of fire that can help you cripple them quickly. You should be as armored as possible(Power Armor is a godsend). You should also make sure you have plenty of Stimpacks available and set to a Hot Key, so that you can instantly heal if one gets close enough to do damage. The Flamer is also a good weapon, they where weak against fire in Fallout 1 & 2 and it seems to do pretty decent damage against them although you have to go in close range.

Other Options: Two of best weapons to take down are the Bottlecap Mine and Dart Gun respectively. The Dart Gun does minimal damage to them, but instantly disables both thier legs, removing thier jump attack and making it easy for you to fire at them while backpedalling. The Bottlecap Mine is also a great for taking them down, simply toss one down, back up a bit, and get thier attention. Even with minimal Explosives skill it will nearly instant kill them, typically finishing off any long range damage you started.

While once in a blue moon you can find a solitary Deathclaw roaming about(this author's first encounter with one was that one attacking a group of Raiders near Arefu, which was pretty early in the game), there is also one roaming outside the Super Duper Mart, there's also the very real danger of stumbling into a nest of them. In particular, the town of Old Olney, on the northeast section of the map(between Vault 92 and the Republic of Dave) is overrun with them. Needless to say, if one Deathclaw is a tough proposition, a group of three or four of them will usually mean you'll be loading a previous save...

It is also worth mentioning that later in the game once the Enclave has made themselves known to the PC, small contingents of Enclave Soldiers may have crates with them that contain a solitary Deathclaw. If opened, the combination of Enclave Soldiers and this beast can easily require a Mini Nuke as the only viable solution.

Quotes

 * "The Deathclaw is the most evil thing to rise out of the ashes after the War. Some say it's a powerful ghost from the war that haunts the land. It's no ghost, it's as real as you and me. It's 20 feet tall with teeth as big as your arm.  It's some kind of demon that found it's way here when the world was engulfed in fire." - Beth (Beth's dialogue file)
 * "The Deathclaws are all over in the Boneyard. I'd rather not even think about them. Huge and aptly named." - Katja (Katja's dialogue file)
 * "Okay. Well, it's like a damn big man, is what it is.  Got spikes and claws that can cut through the heaviest armor.  But don't let the size fool ya, it's quick." - Harold (Harold's dialogue file)
 * "You can't look at 'em! It is said the Death Claw can hypnotize just by lookin'.  Then it walks up and "boom", you're et!" - Harold (Harold's dialogue file)
 * "Heard some tales about something faster, bigger, and meaner than any living creature has a right to be. Not too many, though, which means that it doesn't leave many survivors. Big claws, ferocious disposition." - Tycho (Tycho's dialogue file)
 * "The Death Claw? Oh, that's a bedtime story. Drinks blood and howls at the full moon." - Killian Darkwater (Killian's dialogue file)
 * "I heard a tale from a traveller up from the south. He said the Death Claw was a creature that killed people at night.  He said no one can catch it, because it can disappear like smoke.  Not that I believe it, of course." - Tandi (Tandi's dialogue file)

Appearances in games
Deathclaws appear in all Fallout games. In Fallout Tactics hairy, talking deathclaws appeared. While them being hairy can be easily explained by additional mutations, their intelligence before the Enclave even started experimenting on making deathclaws intelligent is inconsitent with the canon.

Behind the scenes
The deathclaws are a homage to the Shadowclaws in Wasteland. In Scott Campbell's original concept art (see: gallery), deathclaws were mammals covered with fur. The reason it lost the hair from concept to production was a technical limitation of the rendering software, which couldn't get all the hair to move properly. The hairy Deathclaw in Fallout Tactics was inspired by the original concept.

According to the Fallout Bible, after a Dungeons & Dragons computer game made by Interplay was cancelled, deathclaws were modelled (visually) on the Tarrasques of the D&D canon, as a Tarrasque clay model was already made. However, according to Chris Taylor, while they do look Tarrasque-like, it was not intentional and the clay model was supposed to be a deathclaw from the start. .
