Even Shake Has Standards: He may be a selfish, greedy bastard with no remorse for his often absentminded actions, but even he draws the line at certain things, such as poisoning small children with chemical filled balloons at their own birthday parties.
Implausible Deniability: Shake is the kind of guy who'll suddenly reject an idea he previously clung to with his life.
In Name Only: Frylock's the real leader. Shake calls himself "Master" because it sounds cool.
Jerkass: Unrepentantly lazy, rude, selfish, greedy and, particularly in the earlier seasons, downright abusive towards Meatwad. "Video Ouija" demonstrates that Shake is even willing to commit suicide just to abuse Meatwad further.
Supreme Chef: Despite being not capable of doing anything, Shake was shown to be really good at cooking, making four-cheese lasagna, cheese-injected fried beef and cakes. Downplayed, since Shake will cook only for a 'special occasions' like screwing up Meatwad's diet or torturing Carl. In other times he wouldn't mind eating even cat food.
Villain Protagonist: The Aqua Teens are only really detectives from the first three episodes. Once the concept was dropped, Shake, to this day, commits many atrocities that would land him in the clink...which actually happens on a few occasions.
The Kirk: He tries to be the mediator between Shake and Frylock, but he's just too laid back to make much of an impact.
Living Toys: They're not really toys, but he can still talk to them. The others can talk to them in "Shake Like Me". In "Dumber Dolls", Frylock buys him an actual living toy, which turns out to be The Eeyore.
Shock and Awe: In "Balloonenstein", after Shake puts him in the dryer for a week.
Too Dumb to Live: Although he's not nearly as self-destructive as Shake, he still has his moments. In one episode in which Shake covers the floor with land mines to deal with their rat infestation, Meatwad ends up setting off more mines than the rats do.
Image Song: "I Don't Need No Instructions To Know How To Rock!"
Jerkass: Though not as much as Shake, but that's probably not possible.
Jerkass Has a Point: Carl's case is also understandable given how he bears the brunt of the Aqua Teen's antics.
Noodle Incident: Mostly centered around his friend, Terry, who's been in jail for crimes too gruesome to mention, even on a channel like Cartoon Network.
Only Sane Man: Carl's an ignorant, sex-crazed, crude, lazy bum. On any other show, he'd be the wacky next-door neighbor. However, since he's the neighbour of the Aqua Teens, he's the sane one by default.
Humans Are Morons: This is the opinion held by Igignokt and Err, believing that they are superior to all life on Earth in every possible way. Unfortunately, they themselves are not all that smart and are always ultimately shown to be dumber than just about everyone they ever meet on Earth—human, food product, or otherwise.
Hypercompetent Sidekick: Both of them are dumb, but Err sometimes shows more signs of intellingence than Ignignokt, despite his follower status.
Leitmotif: Though the full version never plays outside of the credits (and even then, each episode gets a different verse), the Mooninites do have a theme song, a few riffs from which always appear in episodes where they feature.
Out of Focus: They appeared much less frequently as the show went on.
The Power of Rock: In one episode, they get their hands on the Foreigner Belt—a belt that gives the wearer superpowers based on the band's songs. For example, setting the belt to Cold As Ice gives freezing powers.
Red Oni, Blue Oni: The serene and haughty Ignignokt is blue, while the hyper and aggressive Err is red.
Retr Aux: All moon people are designed to look like 8-bit video game characters. The original plan was to portray them as refugees from a failed Atari game.
Rogues Gallery: They're the most recurring "villains" of the show. Their only real ambition is to rob stores.
Small Name, Big Ego: Ignignokt and Err are always rambling on about how the moon is superior to Earth, but when challenged on it, they can't even explain why.
Sophisticated as Hell: Ignignokt's manner of speech is slightly this. He also owns a stencil with "fart" written in italics.
The Woobie: Err tries to invoke this in "Moonajuna". Doesn't work on Frylock.
Vitriolic Best Buds: Their dynamics are more functional compared to Aqua Teens or Plutonians, but still involve a lot of dissing and snarking at each other, and also, this gem from the movie:
Err: Look man. I'm here for you, it's Ok. Now, what I want you to do, is drink this. [handles a bottle to Ignignokt] Ignignokt: [takes the bottle and drinks] Thank you, Err. What was that thick shake? Err: Well, I'll tell you what it is. It's a mayonnaise i found in a trash can. Ignignokt: Ugh! Err: And it had hair on it! And you drank it! Because I'm your doctor. Do what i say!
The Plutonians (Emory and Oglethorpe)
Pointy aliens from Pluto.
Achievements in Ignorance: They manage to create someone with a vague resemblance to Shake just handing him a photo of Shake, tossing him in a pizza oven, and telling him to wing it.
Anti-Villains: Despite their efforts, they are simply too dumb to make use of them.
The Ditzes: Whilst the Mooninites aren't the brightest of beings themselves, it says something that the Plutonians (especially Oglethorpe) easily fall for their pranks in "Spacecataz" and are hardly able to top them.
Hyper Competent Sidekick: Emory is a lot smarter than Oglethorpe, and is much more in tune with reality than he is. Either due to a weak personality, or just not caring enough to say no, he still goes along with what Oglethorpe says.
Insufficiently Advanced Alien: While their ship is sufficiently advanced, they (mainly Oglethorpe) are unbelievably stupid and clearly know nothing about how it works. It's even been shown that they don't even know how a simple reading lamp works.
Only Sane Man: Emory is a lot more grounded in reality than Oglethorpe.
Poirot Speak: For some reason, Oglethorpe has a German accent.
Put on a Bus: Only made a few cameos after The Movie, but they're scheduled to reappear in the Season 10 finale.
Oglethorpe: We have successfully traveled beyond both space and time through the Fargate...to get free cable! Emory: I think it's a star...gate? Oglethorpe: It's the Fargate. F. It's different from that movie which I have never seen, so how would I copy it? Emory: Chill, man. It's all right, let's just turn it on. Oglethorpe: I just want to make sure we are clear that it's the Fargate. Goes far, get it? And there is no way it came from that movie or that syndicated series based on the movie. Emory: But...it sure was a good movie. Oglethorpe: Yah, yes it was.
Too Dumb to Live: The only characters in the entire series that are dumber than the Mooninites. Well, Master Shake is actually right beside them in this case.
Oglethorpe: [After "trapping" Shake in some circular floating laser rings, he brings down a disco ball, believing it to be a god.] Orbnoticus, we seek wisdom; to what evil plan do we put our new slave to use? [No reply] Emory: ...Maybe he's sleeping. Oglethorpe: DO NOT INSULT ORBNOTICUS OR YOU SHALL BE DAMNED FOREVER TO THE FORBIDDEN ZONE!! Emory: I'm just saying, maybe we should call the installer. He's the same one who installed the laser rings. Oglethorpe: [Looks over and sees Shake is no longer in the rings.] THE PRISONER! HE'S ESCAAAAAPED!! Shake: (Standing right next to the rings) Um... I'm right here. Hey, cool disco ball. Oglethorpe: No, this is Orbnoticus, our leader. Shake: Then why ain't he saying Jack crap? [In the background, we see the spaceship they're in suddenly begin hurdling down toward Earth.] Emory: Yeah, man. How come? Oglethorpe: That is his wisdom. Obviously he's busy navigating us through the stars and— [Suddenly notices they're about to crash.] OH MY GOODNESS!! [Spaceship crashes, Emory and Oglethorpe, carrying the disco ball rush out of a hole in their ship and run away.] Go, go! Emory: I'm going! Oglethorpe: Do not look back, just go!
The Cybernetic Ghost of Christmas Past From the Future
Running Gag: He always wants to return to his home planet, whether it's Dick Planet, Tooth Planet, or Burger Planet.
You're Insane!: And by "Creature From Plaque Lagoon", he's fully aware of it.
Frylock: You're a madman, Wong Burger!
Wong Burger: Eyeah, I KNOW THAT!
Voluntary Shapeshifting: In each of his appearances after "Dickesode", he's modified himself with a different body, changing from a "dick with balls of rage", to a tooth, and then a giant hamburger. He always keeps his face and glasses, though.
MC Pee Pants: We take these monsters, right? We start a haunted house! Yeah? Yeah, and people'll be coming up to the haunted house thinking it's gonna be all scary and shit, but in fact, the house is also for sale 'cause it's a condo, get it? Like in "Hilton Head." And people are gonna pay big-ass cash money to buy this, right? And then we take all that money and buy MORE psychedelic mushrooms, YOU FEEL ME?!
That's supposed to be a plan to "defeat" the Aqua Teens. And "Defeat," in this case, is very ill-defined.
Disproportionate Retribution: Several times. He once spliced his roommate Randal's DNA with a fried pork chop for not paying his half of the utilities. Another time, he sent spiders through the phone line to attack a telemarketer. Then there was the time that he pulled his brain out of his head and started firing lasers at Steve because Steve didn't bring him lunch. There was also the time that he fired several exploding tacos from his mouth at the janitor for picking up his medallion.
Turns out to be a zigzagging trope as Dr Weird then insists Fry is his father, then Walter Melon shows up and says he's all their fathers. By the time their mother, a seven layer burrito, shows up, nobody except Meatwad even cares and the movie goes straight to credits.
Significant Name: Everything that he does is weird, though this could be explained by him living in what once was an insane asylum. His antics include teaching his ass to eat his hand, making love to (and impregnating) a lawn mower, sending spiders through the phone lines to telemarketers, tricking Steve into allowing corn to mate with him...twice, using a chain saw to cut off his flesh in order to lose weight, injecting himself with large amounts of barbecue sauce, cutting off his own head so that the blood spraying out of his neck will propel him all the way to Phoenix, asking Steve to agitate a snake coiled up inside his helmet, and much, MUCH more.
