S.S.D.D. is a long-running (in both senses) British Furry Comic about four people who share a flat: Norman Gates, an Axe Crazy anarchist rabbit who's destined to overthrow the government and found the Collective of Anarchist States; Richard Edwards, a fox and Norman's best friend, also the landlord; Kingston, a constantly stoned hare; and Rich's girlfriend Anne Winters, who's somewhat unstable but is also the only one of them with a job. There are also a few time travelers attempting to prevent Norman's revolution, including Space Marine Tessa Edwards, who is a probable descendant of Rich and Anne; Dr. Cook, the Mad Scientist who developed Time Travel; and two robots, one of which is Tessa's boyfriend. In addition, there is an AI known as the Oracle who seems to be secretly manipulating Norman and will be the real power behind the CAS in the future.
Let's start with the Oracle, shall we, and go from there.
Other AIs seem prone to "Nexus Syndrome" unless caps are placed on their intelligence (sometimes even then). Typical symptoms appear to be boredom, seeking other interests, and turning on your masters (which was a good thing in Tin-Head's case).
All In The Manual: In recent years the author has often substituted comic updates with text detailing aspects of the SSDF world or quotes from various characters.
The Alternet: The Maytec Consortium runs a very fast, secure, and expensive network. The Internet is effectively run by the Collective of Anarchist States and banned pretty much everywhere else, though it's still popular because the Maytec network doesn't have free porn or bootleg movies.
Amoral Attorney: Gary Hart, and not just in the courtroom, he's also a Pyro Maniac with a hobby of blowing up golf courses. It's telling that Norman thinks he's crazy.
Anarchy Is Chaos: The Anarchist Collective sort of goes back and forth. Officially, there are only two laws, "do not profit at the expense of another anarchist" (which can be interpreted to cover anything from scams to murder), and "there are no other laws". The officials in charge are referred to as "Advisers" who don't put out laws so much as "suggestions"; you can technically break them without any sort of official penalty, but since the only difference between local police, angry crowd and lynch mob is how organized they are... The Collective does have a rather intimidating military, not to mention a secret weapon, though.
There's also a reference to "true anarchists" who live in the wasteland between cities, taking potshots at passing vehicles.
Beethoven Was an Alien Spy: The Bush family are androids planted by future Norman to set up the economic collapse. And Ms. Waterman mentions that the Anarchist negotiator who vanished into thin air in Cook's lab was named Jules Verne.
BFG - Tessa's plasma cannon, though apparently it "takes a special kind of lunatic to not only strap a small fusion reactor to their backs, but to also run around a battlefield with one too"
Boxed Crook - The "dirty half dozen" that made the Oracle were all hackers that got caught (the agency didn't have a big enough budget to legitimately hire decent programmers, so they resorted to "slave labor").
B Side Comics - two, Sticky the Stick Man and Church of Poisoned Minds, which eventually became their own comics
City on the Water - The Britannia, a super-sized aircraft carrier made from an iceberg that was bought by a number of wealthy Brits around the time of the Anarchist revolution. Tessa's from the lower decks.
Clone Army: The Anarchists use clones known as "Gigglers" as Cannon Fodder. They're engineered to feel no pain and are grown at an accelerated rate that leaves them no time for an education so they're dumb as rocks. They're controlled using an implant that pumps them full of happy drugs when they do something right, hence the name.
Lee is a clone grown by the Anarchist's enemies, the CORE, using a stolen cloning rig that was given to their R&D department. He was grown at a normal rate so he is smart, but still a bit flaky.
Cloning Body Parts: It is possible to clone biological body parts, but most CORE troops prefer to upgrade with cybernetics.
Cloud Cuckoo Lander - Lee, in fact the entire squad was chosen because they were psychologically unstable.
Cerebus Syndrome - The comic was originally just random gags, but starting with the SSDF story arc it became much more serious, at least in the storylines involving future characters, which is pretty much the main story line now.
Conscription - Tessa was sentenced to serve in the CORE for two years for hitting a policeman. Apparently most member nations have a similar form of the draft.
The Anarchists on the other hand actually call their military the "Volunteer Force", but they can afford to forego conscription as they use a lot of clones and robots.
Contagious A.I. - The thing that makes the Oracle different from other AIs, because it can copy itself to other computers it can increase its processing power unlike AI that are bound to their original frames. In fact its creator was an expert in writing viruses.
Divided States of America - the "Tower Of Babel" storyline starts with an animated map of the states and their progressive division. At the start of the storyline the Anarchists control the northeast states out to Wisconsin and Illinois, the Texans have expanded eastward to the coast, the west coast is controlled by Maytec, and the rest is still the U.S. Currently Texas is split in half by the Anarchists and Americans.
It was recently revealed that Richard acquired their house due to his father buying properties in his name as a tax dodge, presumably this is how Rich also got the other flats he owns (whose residents apparently pay rent).
Gargle Blaster - The squad manage to get drunk on 99% proof cider, it comes with a "do not drink" warning label because they can only sell it legally as paint thinner.
Gambit Roulette - The Oracle is a regular Chess Master most of the time due to his ability to run simulations and knowledge of Time Travel, but another time machine in close proximity can throw him off.
Genius Ditz: Trisha, the ditzy Maytec AI, is, according to some analysts, very good at her job of halting official complaints and attempts to return products. And hypothesizes that she was designed to act like that to customers, but AIs are such drama queens that she couldn't help hamming it up at every opportunity and everyone else began expecting her to act like that so she not only acts stupid to everyone she pretty much is stupid. The occasional homicidal thought notwithstanding.
Going Critical: There's one arc that handles a fission reactor about to go critical realistically, with a lot of failsafes that had to be sabotaged and the main danger coming from it being the radioactive and very hot water. The fusion reactors in plasma cannons also tend to explode but that's explained as the container walls superheating when magnetic containment of the plasma is lost, larger fusion reactors have enough space for the plasma to dissipate harmlessly.
Healing Factor - one of the advantages of the implants Tessa and her squad are testing.
Lee: (fork pops out of his foot) "Ooo! 21 seconds! That's faster than the old implants! But this isn't a fair test. For one this isn't scientific standard cutlery.
Heroic Comedic Sociopath - Norman Gates, though the only "heroic" thing he's done was stopping (violently) a robber at a convenience store, at least that's how the local press made him look. Tessa seems to be a borderline case, particularly in the current arc.
Human Popsicle - The future Norman Gates was frozen for centuries after his supposed death and cryogenics is routinely used for interplanetary travel.
Another time, Tessa was mistaken for dead and put in a freezer, she survived freezing thanks to her implants, including her mechanical heart that doesn't produce a pulse and caused the confusion in the first place.
Humongous Mecha - The Texans use mechs that resemble a cross between AT-ST's and tanks, it was joked that many CAS soldiers have been killed trying to trip them with cables instead of just throwing grenades from a safe distance. The other power blocs use sub-sapient robots with heavy weapons, such as the treaded Inlay Rook.
Identical Grandson - It's noted that Norman's lawyer Gary Heart looks a lot like Captain Jack Heart despite the 400 year gap between them, though Jack also states that Norm is his godfather so time travel may have been involved. Also Tessa Edwards looks a lot like both Richard Edwards and Anne Winters (Rich's fur patterns, Anne's eyes and hair style).
Immune to Drugs - Kingston, who once claimed that he had enough chemicals in his system to render most of China comatose.
Tessa and the rest of her squad supposedly get this from their augmentations, Lee claimed that it would take "enough alcohol to poison an elephant" for them to get drunk.
Interspecies Romance - While most main characters that are in relationships are with their own species there are a few examples, for example Nathan (cat) and Red (fox), First Advisor Laura Black (rabbit) and Jonathan (fox), and recently Anne seduced Nathan to try to find out what he was hiding (Richard wanted her to question him but that probably wasn't what he had in mind).
It Seemed Trivial: Because nobody talks to Michael, he is the only one of the group trying to stop the Oracle who knows about the Echelon Plug-in, which Michael had a copy of. Michael, on the other hand, has no idea what the Oracle is. In other words, nobody knows the two programs are one and the same, which means the Oracle already exists in Michael's time.
Kill Sat - The Tower of Babel is unusual in that the actual satellite is only a mirror designed to redirect maser beams fired from a very large, very phallic tower. The Anarchists use it in combination with a nuclear strike to defeat the Texans (the tower took out their anti-missile defenses and then the nukes vaporized their military bases, and unintentionally Austin).
Longevity Treatment - At least two members of Maytec's board of directors are 30 years older than they look as a result of expensive implants. A comment by Central suggests that they were included in Tessa's implants.
Long Runner - Started in September 1998 and is still updating multiple times a week.
Missing Floor - A supposed 'storage installation' in the middle of the desert hosts a top-secret research-lab in a hidden basement. Once again, it can only be accessed by hitting the elevator buttons in a specific order. Or by blasting the panel, apparently.
Morning Sickness - At the start of the "Anne's Pregnant?" arc (turns out to be a false alarm).
Nano Machines - Were retconned in as Tessa's implants (previously implied to be just Cybernetics).
No Ontological Inertia - Subverted, objects sent back in time are apparently permanent. During the early stages of the Philadelphia project Dr. Cook found a PDA from one of his co-workers with information from two weeks in the future (in particular stock market data) and even after the original PDA was locked up and prevented from being sent back the future version persisted and the data on it didn't change.
Parental Sexuality Squick - Tessa's adoptive parents have an embarrassingly open relationship, possibly why she was still a virgin when she was conscripted.
Personality Chip - Sticks apparently had somewhat limited intelligence before he was modified, though it's implied that he actually had an inhibitor removed rather than having anything added. Most strong AIs seem to develop personality on their own unless preventive measures are taken.
Plasma Cannon: The Black Rose Mk. II was Maytec's brief foray into this type of weapon. During the Mars war they gained a reputation for killing as many of their wielders as enemies and were discontinued. Regardless, Tessa owns one.
Polyamory: Richard roomed with a "lesbian" couple in college, when one of them, Red started to feel attracted to him her partner suggested a threesome just to keep her interested. Things fell apart rather quickly after that.
Poor Communication Kills: Michael is regularly kept out of the loop. This bites everyone in the butt when it turns out he knows the origin of the Oracle, but doesn't have enough information to make the connection.
Powered Armor - Tessa and her squad tested armor that was controlled using their implants, unclear if they become standard issue at all.
Prescience Is Predictable - An unintended consequence of the Oracle's programming, he engineers World Wars in order to observe the results.
Private Military Contractors - The CORE evolved from a private security force that patrolled malls and amusement parks before society collapsed. Now they're the main thing holding back the Anarchists.
Reassigned to Antarctica - Before the start of the S.S.D.F. story arc Tessa apparently got drunk and ordered Tin Head to disassemble her commanding officer's car, as a result she was assigned to a decaying space station orbiting Uranus.
It actually seems that most of the personnel on board station E11 are problem cases.
Also some of the alternatives to joining the supersoldier project.
Restraining Bolt - The majority of AIs have limitations placed on their intelligence in order to keep them from getting bored with their jobs and rebelling, though Sticks is proof that the limits can be removed.
Ridiculously Human Robots - AIs without restrictions to their intelligence are usually mind-wiped every other month to prevent them from becoming this, Tin Head actually became bored when his memory wasn't erased and made a Heel-Face Turn by helping Tessa escape the CAS.
Set Right What Once Went Wrong - What Tessa and Dr. Cook are trying to do and the future versions of Norman and the Oracle are trying to prevent. Though mostly because the former's time machine was irreparably damaged by their botched jump.
Sex Bot - Sticks is one of the few male examples of this trope.
Temporal Paradox - Apparently they're purely mental. The Anarchists never captured the Wildfire and acquired Time Travel technology, but they're still zipping through the past in a ship they will never build.
Also Cook got on the Maytec board using stock information from a PDA that he made sure never got sent back in time.
Time Travel for Fun and Profit: Dr. Cook starts a tech company (the one that employs Anne not-coincidentally) in the 21st century, and the whole reason he was on the Maytec board of directors is stock quotes from a PDA that fell through an early time portal.
Theme Naming - The Inlay robots used by the Anarchists are named after Chess pieces, Bishops are heavy infantry, Rooks are the equivalent of tanks, and Knights and Kings are commanders and are apparently the only sentient units. You can probably guess what Arthur's knights are named.
In addition the name 'Inlay' is apparently a reference to the mythology of the rabbits in Watership Down.
Trading Bars for Stripes: Standard practice for CORE member nations. Tessa was sentenced to two years service for punching a police officer, and insulting the judge.
