Note: In this writeup, I am concerned only with the contextual treatment
of the Goa'uld from within the Stargate SG-1 television series, not from the
Stargate movie.
In order to create a successful science fiction series, whether in print,
on television, or on film, it is often necessary to invent a universe to serve
as a framework for the story. This Universe may be much like our own, save for
a few imaginary characters, as-yet-undiscovered technologies, or extrasolar
planets teeming with sentient life. Stargate SG-1 is a good example of this
principle; it presents a largely normal Earth of the late 1990s, which just
happens to be under attack by aliens.
The "alien attack" scenario has become a science fiction cliche, but SG-1
distinguishes itself by the uniqueness of its aliens. The primary adversaries
of the humans are a race known as the Goa'uld, which are parasitic, highly
intelligent, and technologically advanced. It almost seems bizarre that such
a species could rise to power given their physical limitations -- the Goa'uld
require a host in order to survive and to use the technology they have
acquired. Nevertheless, the Goa'uld have been around much longer than humans,
and in their years of evolution have become a formidable adversary. The Goa'uld
think very highly of themselves, and have a habit of enslaving entire populations
under the guise of divinity. They like to keep their subjects in the dark
as far as science is concerned; their technology is kept highly classified and
known as "magic" to those enslaved by the Goa'uld. The benefits to the Goa'uld
from this deception are obvious; by keeping people ignorant, they will assure
a fearful, devoted populace.
Goa'uld biology is explored rather extensively in the SG-1 series. Their
method of reproduction is somewhat strange in that they require a host species
even for the process of making more of their own kind. A humanoid female
inhabited by a mature Goa'uld serves as the Queen; if this queen mates with a
humanoid male, she will give birth to a large number of Goa'uld larvae. In order
to enslave the population of a given planet, a sample of DNA from a denizen of that
planet is required; hence the necessity of the Queen mating with a male. The Queen
posesses the technology to almost instantly create stomach pouches in humans; these
pouches are meant to nurture a baby Goa'uld to maturity. On planets where
Goa'uld rule is long established, the creation of the pouch is generally performed
by a priest on a young child when he reaches a certain age, during a ceremony known
as the Primta.
Goa'uld do not have a physical "gender", per se, but they do tend to pick a
host gender and stick with it. Perhaps over time some "male" or "female" aspects
creep into the symbiote from the host.
A person incubating a Goa'uld larva is called a Jaffa. The Goa'uld use the
Jaffa not only as incubators for their young, but as soldiers and guards of powerful
Goa'uld system lords such as Apophis and Haru-ur. Though the larva does not
control the Jaffa's mind, the vast majority of Jaffa remain loyal to their system
lord because of years of indoctrination and intimidation. The larval Goa'uld
takes from 7-10 years to mature; during this time, it grants near-perfect health
and slowing of the aging process to the Jaffa. The symbiote becomes the Jaffa's immune system; soon after the Primta ceremony (when a young Jaffa receives his first larval Goa'uld), the Jaffa becomes unable to live without the symbiote. If it is removed, death of the Jaffa will occur within a matter of hours. When the Goa'uld reaches maturity,
it is transferred to a specific host, which it will take over completely. If
a suitable host is not found, the Goa'uld will generally emerge from the Jaffa on its own and seek a host. The Jaffa will die; Jaffa are not capable of serving as a host.
The physical appearance of a Goa'uld changes drastically three times over
the course of its life cycle. As newborns, they resemble elongated shrimp, or
pink worms with teeth. Near the end of the incubation period, their color
darkens, and they grow to approximately two feet long; they look a bit like
tiny, legless dragons. Once this dragon-like form enters what is to be its
permanent host, it wraps itself around the spinal column and attaches to the
brain stem. Soon, it sheds its skin (which is absorbed by the host's body) and
fully integrates itself with the host's nervous system. The adult Goa'uld is
somewhat smaller than the mature larva, and though it depends on a host to survive,
it can move from one host to another when necessary (such as when the host body
is dying, or when the Goa'uld wishes to travel in disguise.) Mature Goa'uld
generally enter a host through the back of the neck, leaving a characteristic
scar.
The Goa'uld are described as scavengers, at least where technology is
concerned. They have, however, adapted much of what they have stolen for their
own purposes. The Goa'uld did not invent nor build the system of Stargates, though
they would like us to think they did. Nevertheless, the technology used by the
Goa'uld is, on the whole, far more advanced than anything humans have, and includes:
- Faster than light travel
- Teleportation (like Star Trek transporters)
- Sarcophagi which can bring people back from the dead and
extend the lifespan indefinitely
- Energy-based weapons with small, light power sources
Despite, or perhaps because of, the highly advanced nature of Goa'uld technology,
there are some vulnerabilities to be found. If an infiltration team can find its
way inside a Goa'uld stronghold, good old-fashioned explosives (such as grenades
and C4) can do quite a bit of damage.
Though the SG-1 series diligently continues to clarify numerous Goa'uld mysteries,
many questions remain. Where did the species originally come from? Where is their
"home world", or do they have one in the first place? Why, if the Jaffa does not
communicate with his symbiote, do the little worm things seem to poke their little
heads out on demand? Why are the Goa'uld so obsessed with being considered gods?
(perhaps they are compensating for something?)
On the whole, it seems that the writers of SG-1 have created the Goa'uld with two
principles in mind:
(1. The creatures must be well thought out enough to allow for some suspension
of disbelief while watching the series; we don't want to insult the intelligence of
our target audience.
(2. The creatures' abilities must be such that they continue to be an interesting
and dynamic enemy throughout the (hopefully long) life of the series.
Certainly, someone went to a great deal of effort to dream up a species with
a distinctive life cycle and biological makeup. This helps add to the believability
within the context of SG-1's local reality. It is also apparent that such
technological marvels as the sarcophagus are mainly to assist with plot, specifically,
making it so dead characters (both good and bad) can return.
