Alien Non-Interference Clause: The undoing of Nogg's Plan A. If the humans claim Earth's seat at the G.O.B., then Earth is no longer considered a "dark planet", and is open to exploitation by any planet in the G.O.B.
Always Need What You Gave Up: Yuri's therapist robot erases her memory of torture at Flineous's hand in order to bring her back to sanity. Not long afterwards, she runs into Flineous again, so the therapist is forced to restore Yuri's memories, causing her to revert to her scary, violent self.
Anti-Advice: Dustin thoroughly establishes himself as a dumbass, so when he tries to warn Pierrot against trusting Curn, it convinces Pierrot to do exactly the opposite.
Pierrot: Dusty thinks it's a bad idea, it must be sensible.
Anticlimax: Kuu-Drahc is played up as a major antagonist and personal rival to Emily, culminating in the Combat by Champion scene described below. A random rockslide crushes Kuu-Drahc before the fight even begins. Even Emily is disappointed by this.
Much later, one of the unclamped Eebs is revealed to have survived. He's found and disposed of within five pages and without any fanfare.
Action Girl: Emily is one from the get-go, while Yuri and Martina evolve into the role.
Artificial Limbs: Yuri now has six four of them. Martina later gets a prosthetic arm and eye to replace the ones the unclamped Eebs burned off, which unlike Yuri's are practically indistinguishable from the originals.
Asshole Victim: Major spoiler! The Eebs. Back when they had free will, they were violent and capricious; their own laziness and the other species' lack of challenge was the only thing keeping them from ruling the galaxy with a telekinetic crush-grip.
Dustin. Victim, then asshole, then both simultaneously and continuously for the rest of the comic.
Asteroids Monster: A Ditherker will spawn multiple copies of itself just before dying.
Asteroid Thicket: Brograhm's Teeth, slightly justified in that it's a miniature Big Bang constantly spewing out debris that's often the size of a planet into a black hole.
Badass Longcoat: Emily. She even wears it over her spacesuit. Later, she upgrades it so that it can also be used as a hang glider.
Batman Can Breathe in Space: Yuri's upgrades include a built-in space suit, allowing her to survive the near-vacuum of space without any external help.
Berserk Button: Don't hurt animals around Pierrot. Don't talk about hurting animals near Pierrot. And don't try to force Pierrot to eat meat.
Yuri seems sweet, but if you tick her off, she will mess you up. Just ask Flineous.
Martina is morally conflicted about killing, even in self-defense—but she's not afraid to stun-gun her own captain to insure that No One Gets Left Behind. And, when backed into a corner, she is willing to kill if it's the only way to save more lives.
Bishonen Line: Yuri's cyborg upgrades cause her to look increasingly inhuman—then her most powerful, "A God Am I" upgrade returns her to humanoid form, just with different skin color.
Black Box: Eeb-derived technology is this to non-Eebs, almost without exception. Even if another species could understand the tech, the Eebs are terrible at explaining it, and everyone else just relies on Eeb slave labor rather than bothering to learn how anything works. And in the specific case of spacetrawlers, the G.O.B. goes to great lengths to hide the truth of their construction and functioning, because this information is very politically volatile.
Dimitri:[regarding a bug-alien he slept with] Pheromones and ventral revealing outfits. Way hot.
Brain Bleach: Yuri seem to give Dimitri reason to ask for some here. Or at least some... uncomfortable cleaning implements. It's worth noting that disgusted/horrified as he is, he's still willing to try it out.
Brick Joke: Russian tea cookies. Also kind of Nogg's promise to Martina, but that isn't really funny...
Gurf's aptitude for fleet commanding. Mentioned by Gurf's mom in #88. Comes up again in #172, squeaking in at just under a year later. Not bad, eh?
Broken Pedestal: Rickshaw Boans, founder of Interplanet Amity, is a huge inspiration to Krep. When Rickshaw returns from parts unknown, he's even more zealous than he used to be, while Krep has undergone Character Development and is no longer so gung-ho about Rickshaw's "shoot first, ask questions later, and take no prisoners" approach.
Chekhov's Gunman: The Man Behind the Man hides in plain sight (both for the readers, and in-universe), well before his true importance to the plot is revealed. He's that nameless guy standing behind Kuu-Drahc at G.O.B. meetings.
Chronic Backstabbing Disorder: Dimitri gives Dal many opportunities to sever her G.O.B. ties and prove her loyalty to him. Every single time, she uses the opportunity to try to kill Dimitri.
Clip Its Wings: Martina doesn't like killing, and suggests shooting the wings off enemy spacefighters as an alternative. Emily, the one manning the guns, thinks it's stupid.
Martina: That said, is there any way out of this without killing them?
Martina: Don't suppose you could just aim for their wings?
Emily:I'M NOT GOING TO FUCKING AIM AT THEIR WINGS!
Combat by Champion: When Emily realizes that her side is outgunned in the space dogfight with the G.O.B., she goads Kuu-Drahc into halting the battle so the two of them can fight one-on-one and hand-to-hand.
Cybernetics Eat Your Soul: Possibly more symbolic than literal, but Yuri's descent into PTSD is accompanied by her cyborg implants becoming less human and more monstrous.
Inverted at the end: Martina tells Yuri that if they're going to stay friends, she needs to remove all her weapons. This process along with getting brain-clamped brings Yuri more-or-less back to her senses.
Even Evil Has Standards: In the story of Brograhm's Teeth's namesake a group of ruthless killers saw the destruction by acid bombs of an entire planet's population, they were so shaken they gave up their life of crime and took low-stress office jobs. The G.O.B. station in the stellar phenomenon known as Brograhm's teeth is staffed by convicted criminals, mostly mass murderers, and the process of making Spacetrawlers has them breaking down in tears.
Everyone Has Standards: Brekt, the loony-sounding conspiracy theorist, is offered a place in Nogg's crew. She turns it down: "I may be nuts, but I'm not that crazy!"
Fake Weakness: Easy to pull off when one's torturer knows nothing of human physiology. "No! Dear God, don't make me eat chocolate! It burns!" Until they decide to start cutting off limbs instead...
Faking the Dead: Dimitri uses holograms to convince the G.O.B. that their assassin succeeded in killing him.
Fantastic Racism: In the Spacetrawler universe, grounds for legally declaring a species non-sentient include lack of willpower and bad fashion sense. (On paper, at least. Political expediency seems to be the real reason: non-sentient species are easier to exploit.)
When it becomes necessary to forcibly restrain Yuri, Martina uses a bomb that Yuri herself asked the Eebs to make.
Major spoiler! The Eebs invented the brain clamp technology, and they were the ones who started using it on themselves. By the time the rest of the galaxy decided to enslave them, only a half-dozen of them remained unclamped.
Dimitri loves Dal, and she might reciprocate, but she's more committed to the G.O.B.
Dimitri and Haldeyis have a strong relationship until his new job with the G.O.B. leaves him unable to spend time with her.
Curn and Oohlooh.
Martina and Luunock. Nogg does some hasty backpedaling when he realizes Mr. Zorilla doesn't want to hear how far they went.
Pierrot is briefly courted by a Qiyemp female. He breaks up with her on Carpsellon and leaves her to comfort the dying Kuu-Drahc, shortly before the destruction of the planet.
Irony: Of the Situational variety. Rickshaw Boans suspects that Krep is not sufficient committed to the cause, so he kicks Krep out of Interplanet Amity to prevent him from undermining the latest mission. This act finally convinces Krep that Rickshaw isn't such a great guy after all—and prompts him to go and deliberately undermine Rickshaw's mission.
It Tastes Like Feet: Dimitri points out that the coffee tastes like asteroids. After all, it was synthesized from space debris.
Klingons Love Shakespeare: Dimitri licenses his recipe for Russian tea cookies. It becomes wildly popular on multiple planets, and Dimitri makes a fortune.
Lampshade Hanging: Mr. Zorilla calls out Nogg for the way his narrative jumps between plot threads willy-nilly, and for the gratuitous cliffhangers.
Laser-Guided Amnesia: It's a relatively trivial procedure to erase (or restore) memories. The subterranean Mihrrgoots make liberal use of this to prevent the outside universe from learning of their existence. And the therapy-bot (who used to be a bar-bot) speeds up Yuri's counseling by erasing her traumatic memories.
Mad Scientist: Eebs, when given vague instructions to build something, can have some odd ideas. I.e. when Dmitri told a group of them to construct a means of leaving the hotel without being seen adding legs to the hotel and floating it out on a river of lava have to be shot down before one of them suggests a tunneling machine, that makes beer.
The Man Behind the Man: Qwahntoo is the real brains behind the GOB, and Kuu-Drahc, the apex speaker is just the public face. Amusingly, in his first appearance Qwahntoo is literally standing behind Kuu-Drahc.
No Biochemical Barriers: Handwaved by the approxiscan devices, which scan the biology of encountered creatures to identify compatible foodstuffs, atmospheres, and (to Dimitri's great interest) romantic partners.
Note to Self: Pierrot finds out some important information about the Eebs just before he's scheduled to receive some Laser-Guided Amnesia, so he writes himself a letter summarizing it. Post-amnesia, he reads the letter and almost immediately dismisses it.
No Transhumanism Allowed: Cyborg prosthesis is treated as normal, though not apparently common. But when Choan asks Yuri about her bioaugmentation, Nogg's indignant response suggests that bioaugmentation isn't well-regarded by some folks.
Obfuscating Stupidity: Everyone knows the Mihrrgoots are violent, smelly brutes with a taste for other sentient beings. That's just the surface population who are inbred descendants of a few drunks. The subterranean population is sophisticated and has more advanced technology than the Eebs.
Oh, Crap: Panel eight, here. Somewhat literal, in this case.
Eeb: As an example of our power, we will rain down fire on the nearby planet of Carpsellon and melt every last thing on the surface to slag simply by using our minds. From the information we now have, this "rain of fire" will be analogous to one's morning poo after enjoying a really satisfying spicy meal.
The Eebs are a species of telekinetic gadgeteers with zero willpower. Major spoilers!The lack of willpower is eventually justified—it's a result of the artificial brain-clamping that Eebs receive at birth. However, the unclamped Eebs are capricious, and range from amoral to complete assholes.
The Flimboulxians (i.e. Krep's species) artificially bred stupidity out of themselves. This had a side effect of making them all jerks.
The Tornites all have terrible fashion sense.
It's implied that the Bollycks are all violent and ill-tempered.
Qiyemps are all pacifists, to the extent of being completely spineless.
The Pornomancer: When introduced, Dimitri is entertaining two bikini-clad women in a rowboat. Over the course of the story, he first propositions all the human females, then proceeds to seduce every remotely compatible alien female he can find, regardless of looks or shape.
Powered by a Forsaken Child: How spacetrawlers work, and the real reason why details on their construction are so carefully guarded. It's so bad, that only the most vicious and horrific criminals in the galaxy are used as (brain-clamped) labor on the space station that creates the trawlers, and they each have a moment when they break down and cry like a baby when they see how it is done.
Power Strain Blackout: Eebs (and Yuri with her Eeb brain implants) will black out if they strain their telekinesis by moving objects that are too massive. Too much of this strain can outright kill them. It's later revealed that this limitation is a result of brain-clamping — we've yet to see an upper limit on how much matter an unclamped Eeb can move telekinetically.
When it becomes undeniable that Dal is dangerous to Interplanet Amity and simply cannot be trusted, Dimitri kills her.
When the situation aboard the spacetrawler construction facility gets really bad, and all Martina's attempts to prevent further bloodshed fail, she realizes her best remaining option is to blow up the station, killing everyone aboard. So she does it.
Stupid Sacrifice: Played for laughs when Gurf intercepts a laser blast to protect Emily. Emily then points out that it was a stun-ray, and that the now-unconscious Gurf is the heaviest member of their squad.
Super-Persistent Predator: The Ditherkers that an assassin siccs on Emily are modified to chase their target, and only their target, until they bring it down or starve to death trying. They track by scent, cling to the hull of a spaceship moving at greased-light speed (and don't suffocate), and asexually reproduce when killed.
Nogg: Cardinal62. Tell them we're the good guys. Cardinal62:(To Emily) We're the good guys. Emily: Well, tell alien-fish that I know a dozen good seafood recipes he'd go lovely in. Cardinal62:(To Nogg) She knows a dozen good seafood recipes you'd go lovely in. Nogg: Well, you tell her that —
There Are No Therapists: Zig-zagged. Nogg does have a Therapy-bot for his crew, but it's terrible at the job. Later, Martina recognizes that the crew needs a good therapist, so she replaces Therapy-bot with Bartender-bot, ordering the latter to study and utilize human methods of psychology. He makes some decent progress at first, then the guy who mutilated Yuri shows up and they're back to square one.
Ultraterrestrials: The Eebs diverged from humanity a couple hundred thousand years ago, and used their telekinesis to leave earth when they got tired of dealing with non-telekinetics. The obvious physical differences are due to Eebongbong's higher gravity and something in the food.
Weapons-Grade Vocabulary: When some Eebs were asked to "tell us a joke", they built a computer to synthesize the funniest joke ever. The result is so hilarious that the punchline wiped out the asker's entire species. Fortunately for the rest of the universe, the punchline depends on a nuance of language that gets completely lost in translation, so no one else gets it.
Who Shot JFK?: According to the (possibly-correct) ramblings of a conspiracy theorist, "J.F.K." was an alien shape-shifter and a fugitive member of the secret society (the same one that controls the G.O.B.). He went into hiding by becoming a president on Earth, and the secret society sent an alien assassin to kill him.
Worthy Opponent: Emily becomes one for Growp. That's why he fell in love with her.
Year Inside, Hour Outside: Dmitri goes to the alternate universe on the far side of the Draak-sim and comes back in an hour, with grey hair.
