EPISODES EXTRA 1 -- GOA'ULD PLOTLINES

I just thought I'd give folks New to Stargate SG-1 an idea about the "bad guy" plotlines prior to the ninth season(where other bad guys came into the mix). In this case, we're talking about the Goa'uld, Jaffa, and their related enemies.

Episode No. Title Season Relevance
1, 2 Children of the Gods 1 The Pilot episode takes place one year after the Air Force Team leaves Daniel Jackson on Abydos and returns home.  Though the alien Ra was killed, a new one crops up named Apophis.  We learn that the aliens are called Goa'uld and that their servants, the Jaffa, carry the larval form of the Goa'uld symbiotes in a pouch in their abdomen.  Protecting themselves from the Goa'uld is the main background plot throughout the series.

The subplot is the kidnapping of Daniel Jackson's Abydonian wife, Sha're, and her implantation of a mature Goa'uld named Amonet.  Her brother, Skaa'ra, who is like a surrogate son to Jack O'Neill, is also taken and forced to become a host.  This implantation is the reason behind the title, Children of the Gods, because the Goa'uld that has taken over Skaa'ra is a child of Apophis.  The kidnapping and brutalization of both of them becomes Daniel Jackson and Jack O'Neill's driving force to remain with the SGC as members of SG-1.
3 The Enemy Within 1 Major Charles Kowalsky, assigned as Sg-2's team leader, is attacked, taken over by a Goa'uld symbiote, and later killed.  We find out about how the symbiotes inhabit the host body and what happens when removal of the symbiote is attempted.
7 Cold Lazarus 1 Mostly about an alien race of sentient crystalline minerals, but who were annihilated by the Goa'uld.
8 The Nox 1 An episode which has two things:  The presence of the Goa'uld Apophis, and the introduction of a very powerful race.  In the plotline, both the Goa'uld and the Humans attempt to capture an invisible flying creature in order to learn it's secrets of invisibility.
9 Brief Candle 1 The Goa'uld are discovered to have been tampering with human genetics and nanotechnology.  They have injected nanites into the small population on this one planet in order to speed up the age of humans for use as hosts.  They age incredibly fast.  One year of life takes only one day.  In 90 days, they're usually dead from old age.  However, this "experiment" was left untended and forgotten - until Sg1 gets there and is prompted to discover a means of ending the unnatural aging.
10 Thor's Hammer 1 Thor's Hammer was created by a race of aliens known as the Asgard.  They are the Roswell greys we've heard so much about.  They are currently at an impasse - cold war - with the Goa'uld.
In trying to think of finding allies against the Goa'uld, Teal'c tells of a place where all Jaffa are forbidden to go, a world called Cimmeria, and SG-1 goes there.  Sam and Daniel meet a woman named Kendra, who was a former host to a Goa'uld.  This is important because it is learned that the symbiote can be removed, and the Asgard have the technology to do it.  Another introduction is made here when Jack and Teal'c meet - and fight - an Unas, an alien known as the "First Host" of the Goa'uld.
12 Bloodlines 1 Here is where we learn of the Jaffa and, more specifically, Teal'c's family.  The primary introduction of the 'good-guy' Jaffa Master, who is Teal'c's mentor, named Bra'tac, is this episode.
14 Hathor 1 We learn about a Queen Goa'uld, capable of spawning many larval Goa'ulds.  We also learn that she can create followers due to a chemical she naturally carries in her system.
15 Singularity 1 We learn of the mineral, Nahquadah, or Naquada or Naquaada.
("Naqada" happens to be the name of an Ancient Egyptian city - like Abydos)
The Stargate mineral is the chief mining mineral used by the Goa'uld in all of their technology.  Here, the Goa'uld have made a tiny bomb with it and planted it inside a girl named Cassandra, the only survivor of a Goa'uld-devastated planet.  When she is rescued and brought back to the SGC, they learn that when she gains 2nd contact with the stargate - by an outgoing wormhole - she'll explode, taking the SGC - and more specifically, the Tau'ri gate - with her.
16 Cor'Ai 1 The presence of Jaffa is in this episode.  Background information on Teal'c is learned here when Sg1 travels to a planet which Teal'c had visited before when he was First Prime for Apophis.  Teal'c is imprisoned and put on trial for the "crimes" he carried out under Apophis' orders.
20 There But For the Grace of God 1 Another Presence of the Goa'uld and Apophis.  Introduction of two things: Parallel Universes and a Naquada-made piece of technology - a man-sized "quantum mirror".  This mirror is used to travel to these parallel worlds.   Daniel Jackson inadvertantly travels to one, another SGC and Earth, which is being decimated by the Goa'uld.  He returns to his own world, back to the planet he started from, and back to his searching team members trying to find where he disappeared.  They find him on the floor, holding the coordinates of a stargate address, the source of the Goa'uld attack, and sporting a mysterious wound unmistakably made by a Goa'uld staff weapon.
22 Within the Serpent's Grasp 1 Part 1 of 2.  With the information Daniel Jackson got from the parallel universe, he finally succeeds in convincing the rest of his team to 1) believe that he visited a parallel universe, and 2) to gate to the coordinates he retrieved from that universe.  When they get there, they discover that they've transported to a Goa'uld ship which then departs it's orbit of the unknown planet and proceeds on its mission:  To destroy Earth.  Here we have the return of Apophis and the return of Sha're's brother and Jack's friend, Skaa'ra.  Skaa'ra's Goa'uld symbiote, Klor'el, is dramatically introduced.
23 The Serpent's Lair 2 The conclusion to "Within the Serpent's Grasp".  Jaffa Master Bra'tac returns.
24 In the Line of Duty 2 Sam is invaded by a Goa'uld symbiote named Jolinar of Malkshur.  We later learn that the symbiote, Jolinar, says he belongs to a separate species of Goa'uld called The Tok'ra, who broke away from the genetic memory of the Goa'uld 2000 years ago.  It is learned that they don't take hosts by force.  But this statement is contradicted by the fact that Jolinar refuses to allow Sam to speak.  (I guess the "Tok'ra" concept hadn't been fully ironed out yet).  In Jolinar's defense, he was trying to flee a Goa'uld assassin and planned on leaving Sam as soon as possible.  However, Jolinar was still spouting "Goa'uld-like" mannerisms and actions so he made his case very difficult to believe.
What wasn't difficult to believe was a Goa'uld assassin was dispatched to kill Jolinar and since Jolinar now occupied Sam, Sam was also a target.  We are introduced to the weapon of the Goa'uld Assassin and it's varied uses.
27 Need 2 In this episode, we learn about the very negative effects on the human body gained from excessive use of the Goa'uld sarcophagus.
28 Thor's Chariot 2 The continuation and fallout from "Thor's Hammer".  Two major introductions here:  The First is the introduction of Heru'ur, a nasty warring Goa'uld.  The Second is in meeting the real Asgard, Thor, and Thor's Chariot.  We learn just how much more powerful the Asgard are to the Goa'uld.
30 Family 2 A continuation of "Bloodlines" and fallout from "The Serpent's Lair".  We learn more about the Goa'uld chemical used for brainwashing and supplication.  Bra'tac comes to Earth to bring Teal'c back to Chulak because Teal'c's son, Ry'ac, has been kidnapped and brainwashed by Apophis.
31 Secrets 2 Apophis and Heru'ur are both in this episode, as well as Daniel's lost wife, Sha're, who is now the host to Amonet, Apophis' queen.  We are introduced to Sam's father, retired AF General Jacob Carter, who informs Sam that he is dying of cancer.

The Tok'ra
The Tok'ra Part II
2 Self-explanatory.  In this two-part episode, we learn about the Tok'ra and about Jolinar of Malkshur, Sam's former symbiote.  We also get to see Sam's father, Jacob, again.  SG-1's purpose in finding the Tok'ra is to try and make an alliance against the Goa'uld.  We are introduced to Jolinar's mate, Martouf/Lantash, as well as other Tok'ra, including a dying Tok'ra named Selmac, who needs a new host to survive.
39 Serpent's Song 2 We see the Goa'uld Apophis again, and are introduced - long-distance - to a new formidable Goa'uld named Sokar.  Sokar is the one Goa'uld who has been banished from the System Lords.  Sokar's adopted persona is that of the Punisher, later known as the christian "Satan" or "The Devil".
Martouf/Lantash returns to warn them about Sokar.  After this, we are introduced to another form of Goa'uld technology:  a particle beam laser, which Sokar fires through another planet's stargate to try and burn through the Trinium-based Iris covering the Stargate.
40 Holiday 2 The introduction of anti-Goa'uld traps - technology created by a dying man named Machello.  One of Machello's inventions causes two people to switch bodies and he tricks Daniel Jackson into trading bodies.  Daniel then becomes the dying old man.  Machello's anger at having his life turned upside-down by the Goa'uld takes it's toll on Daniel and his friends.
42 Show and Tell 2 Another enemy of the Goa'uld are introduced here:  The Reetou.  They send an emissary in the form of a small boy to warn the people of Earth about a militant faction of Reetou bent on destroying all possible hosts to the Goa'uld, including all humans.  Jacob Carter and his new symbiote, Selmac, show up to help.
44 Out of Mind 2 The Goa'uld Queen Hathor returns.  Part 1 of 2.  A new piece of technology is used, called the Memory Recall Device, which stimulates memories and can display them as holographic images.
45 Into the Fire 3 Conclusion.  Jaffa Master Bra'tac returns.
46 Seth 3 Jacob Carter/Selmac shows up with a mission for the SGC and SG-1:  to find a Goa'uld who's been hiding on Earth since the time of Ra, four thousand years earlier.
47 Fair Game 3 The Goa'uld System Lords have decided that Earth is too much of a threat to be ignored.  Thor shows up with his ship to tell the SGC that three members of the Goa'uld System Lords are coming to Earth to participate in a treaty negotiation.  Earth will either join the Asgards' protected planet status or they will be destroyed.  As the Goa'uld-compensation part of the treaty, the Goa'uld ask that The Tau'ri give up their stargates.
The Three Goa'uld System Lords introduced are:  Cronus, Yu, and Nurti.
48 Legacy 3 Another anti-Goa'uld invention.  The Goa'uld inventor, Machello, attacks from the grave by way of one of his inventions, like a long-forgotten land mine.
49 Learning Curve 3 We learn a little about a Nahquadah reactor/generator when Sam is taught how to build one.
50 Point of View 3 The parallel universes come into play again as a parallel Sam Carter and Charles Kowalsky enter our universe to escape the Goa'uld invasion of their own Earth.
51 Deadman's Switch 3 A bounty hunter, working for the Goa'uld, coincidentally snares SG-1 while tracking a Tok'ra.
52 Demons 3 A village during Medieval Times on Earth has been moved to another planet by the Goa'uld.  The population is one of religious superstition and oppression and is terrorized constantly by an "Unas" Goa'uld.  We learn here that Sokar, posing as Satan, uses the Unas Goa'uld to frighten the villagers into giving up "the unclean" so that Satan may claim them - and the Unas sends them through the "circle of darkness" (stargate) to be hosts.
53 Rules of Engagement 3 The Goa'uld have a battalion of Jaffa training in War games on a planet.  But they are training as members of the American military, not as Jaffa.
54 Forever in a Day 3 Amonet returns.  We learn of the unusual use of the Goa'uld hand device and that the boy that Sha're/Amonet gave birth to, known as a Harcesis, is the holder of all Goa'uld secrets and memories and must be kept from the Goa'uld.   Sha're tells Daniel that Amonet has hidden him away in a place called Kheb.
56 Jolinar's Memories 3 Martouf (we don't hear from Lantash) returns to get help in rescuing Jacob Carter, taken captive by Sokar.  We get to see the face of Sokar, as well as his altered moon, Naetu, which resembles "hell".  We are introduced to another Tok'ra named Aldwin.  The supposedly dead Apophis returns.  Part 1 of 2.  The memory recall device is used again, but without the holographic images.
57 The Devil You Know 3 Conclusion to "Jolinar's Memories."
59 Pretense 3 The return of the aliens called the Tollan, who were introduced in the first season episode, "Enigma."  Here, they have easily defended themselves from an attack by Heru'ur.  The Abydonian, Skaa'ra, Sha're's brother, returns.  Klor'el/Skaa'ra flees one of the Goa'uld ships and crashes on the Tollan planet.  It is Skaa'ra who awakens first and he asks the Tollan to remove the symbiote, Klor'el.  We are introduced to another Goa'uld, a lesser warlord of Apophis' named Zipacna.
New Tollan technology is introduced here.  The first is the device which suppresses the Goa'uld symbiote's ability to silence it's host.  The second is the ability to remove the symbiote from the host, with the help from the Tok'ra.
64 Maternal Instinct 3 The Tale of the Harcesis child continues.  Master Bra'tac returns and a new alien race is revealed on the planet Kheb.  The main alien is called Oma Desala - Mother Nature - and she is the Harcesis child's protector.  Apophis' new troops come to Kheb to take the child and miserably fail.
65 Crystal Skull 3 Another enemy of the Goa'uld is discovered.  We are introduced to Daniel Jackson's grandfather, Nickolas Ballard.
69 Upgrades 4 A new Tok'ra, Anise/Freya, shows up.  She brings with her alien technology to test on Sg1, who are ultimately to be used in a covert mission to blow up a new ship being built by Apophis.
70 Crossroads 4 The introduction of a Jaffa temple priestess, Sho'nac.  She comes to the SGC from Bra'tac to see Teal'c, her childhood sweetheart.  She thinks she's discovered a way to turn her symbiote against the Goa'uld.  Anise and other Tok'ra return.  Sho'nac's Goa'uld symbiote is named "Tanith" and his new host is Hebron.
70 Divide and Conquer 4 Martouf returns.  Anise/Freya return.  We are introduced to a new Tok'ra, their new leader, Per'sus.  A Tok'ra technology device is introduced here, called the advanced memory recall device, used to detect a Zatarc, a person who has been unknowingly programmed for terrorist attack.  It is like an advanced lie detector.
The weapon used by the programmed person is very similar, in shape and how it's worn, to the weapon used by the Goa'uld Assassin sent to kill Jolinar.
74 The First Ones 4 The first hosts, the alien race called Unas, are discovered, living in an aboriginal society.  The planet they are discovered on is also home to the original Goa'uld symbiotes, which live in a large lake, unhosted.  As they attack an Unas and gain a host, they then travel through the stargate.  This explains why there are no hosted Goa'uld on the planet.  We also learn that these original Goa'uld have no naquada source and therefore, no power.  It may be the reason why the planet was seemingly abandoned.
77 Point of No Return 4 An alien race flees a Goa'uld attack and hides on Earth.  One of them, forgetting who he was and where he came from, becomes a conspiracy theorist and contacts the SGC.
78 Tangent 4 The scientists at Area 51 have created a modified craft from the Goa'uld death glider.  Jack and Teal'c have the task of test flying the craft, and naturally, things go wrong.  Jacob Carter/Selmac returns to help.
79 The Curse 4 Daniel Jackson's academic past is examined and a new Goa'uld, claiming the persona of Osiris, is introduced.
80 Serpent's Venom 4 Jacob Carter/Selmac returns.  Apophis and Heru'ur return.  A few new Jaffa leaders and another lesser Goa'uld are introduced.
Jacob/Selmac returns to get Sg1 to assist in foiling an alliance between Apophis and Heru'ur.  Teal'c is not with them, however, having gone to Chulak to recruit more Jaffa against the Goa'uld.  Teal'c ends up aboard Heru'ur's ship when it confronts Apophis' ship, all the while Jacob/Selmac and the rest of Sg1 are busy trying to pit Heru'ur and Apophis against each other.  A new method of cloaking technology is revealed by Apophis.
83 Absolute Power 4 The return of the Harcesis child.  The technology of using nanites to ensure rapid growth of a human is examined again.  The evil susceptibility of Goa'uld, due to the passing on of genetic memory, is also examined.
84 The Light 4 Introduction of technology used by the Goa'uld for purposes of relaxation.  Daniel euphemistically calls it "an opium den."
87 Double Jeopardy 4 The return of the fallen System Lord, Cronus.  Also, the return of characters from the 1st season episode, "Tinman":  the clones made from SG-1.
88 Exodus 4 The return of Jacob Carter/Selmac, the Goa'uld Apophis and the new Goa'uld/Tok'ra spy, Tanith.
89 Enemies 5 Continuation from Exodus.
90 Threshold 5 Probably the last episode for Bra'tac, who comes to aid Teal'c in recovering from Apophis' brainwashing.
91 Ascension 5 Incidental relationship to the Goa'uld.  The planet SG-1 visits holds a weapon used to defeat the Goa'uld.
92 The Fifth Man 5 A chameleon alien who uses memory as well as sight.  He tricks SG-1 into thinking he's one of their team, a Lt. Tyler, in order to escape from the Goa'uld.  Jack and Tyler are caught behind the lines in a Jaffa-occupied territory.
94 Rite of Passage 5 Cassandra, from "Singularity", is also the victim of Goa'uld genetic tampering.  Nirrti:  The Goa'uld who poisoned her planet and planted a naquadah bomb inside her chest makes a good impression here.
96 The Tomb 5 Introduction to the Goa'uld, Marduk, who dies.  We also learn that Goa'uld can inhabit any kind of host body when it inhabits the body of a creature-critter that was meant to kill him.
97 Between Two Fires 5 The Goa'uld, Tanith, is now working for Anubis (although no one knows his name in this episode) and he and his "master" attack the Tollan homeworld, while being protected by new shield technology impervious to the Tollan ion cannons.
99 Desperate Measures 5 Sam is kidnapped for medical study by the employees of a dying rich man who plans to implant himself with a Goa'uld symbiote.  Sam's medical clues are 'supposed' to lead them to answers in how to remove the symbiote after it heals it's host.
101 Proving Ground 5 Training exercises designed specifically to combat the Goa'uld
