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.
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.
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").
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.
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 it's processing power unlike AI that are bound to their original frames. In fact it's 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).
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.
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.
Well no the Oracle was developed to predict the future, hence the name.
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 vaporised 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.
Mega Corp - The Maytec Consortium, considered to be an international power that effectively runs the independent nation of California OW.
Menstrual Menace - Anne when she's in heat, justified in that she has it just once a year.
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.
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.
Xanatos Roulette - The Oracle seems to be a regular Chess Master most of the time due to his ability to run simulations and knowledge of Time Travel, but apparently another time machine in close proximity can throw him off.
