- Lyle, the quintessential Straight Man and Chex's defense attorney.
- Vaporware, the obligatory "wacky" cast member: a robot who dreams of killing all humans and enjoys choking people.
- Polkadot Dream, the obligatory girl: the bona-fide star of her own webcomic, and Chex's unrequited love interest.
Provides examples of:
- Animated Actors
- Bestiality Is Depraved: The revelation that Dot has had relationships with (sentient but non-anthro) cats completely overshadows the revelation that her art style was plagiarized from Chex.
- Call to Agriculture: Vaporware's brief career as a strawberry farmer.
- Canon Welding: In the final strip Vaporware is sealed in a water heater and launched into space. Several millennia later, he is picked up and reactivated by the crew of the Fuseli...
- Cerebus Syndrome: Lampshaded—it's known as Canonitis and it's a potentially-fatal illness.
- Character Title
- Cloud Cuckoolander: Chex.
- Creator Breakdown: Straub has admitted Chex's anger in the strip's later years mirrored his own feelings, and that he ended the comic to prevent it from getting poisoned by his bitterness.
- Crossover: Too many to list them all.
- Crush. Kill. Destroy! / Kill All Humans: Vaporware's stated goal is to exterminate humanity. Mostly he just settles for choking Lyle.
- Deliberately Monochrome: Initially the comic was black and white, then switched to color when Chex visited some other comics. Eventually settled on black and white inside Chex's comic and full color outside the comic.
- Eldritch Abomination: Subverted. We're led to expect a sanity-shattering Lovecraftian monster when we're told that the Unraveled is beyond human comprehension. Turns out it's a being whose enlightenment and selflessness are beyond human comprehension. But then he gets corrupted by the Apocalypse Shard and turns evil during the end of the series. He gets better.
- Final Battle: The first comic ends with an all-out brawl between the main cast, the entire Universe Of Failure, and every character Chex had ever wronged.
- Follow the Leader: Chex seems to be incapable of originality.
- Go Mad from the Revelation: Shrodinger the Cat. He can see every possible reality at once, and has been driven insane by the knowledge.
- Ice-Cream Koan: Anything the Unraveled says.
- Jerk Ass: Chex. He may simply be legally insane.
- Lampshade Hanging: Gets a lampshade hanging itself.Chex: All I have to do is take a bunch of webcomic conventions that people know, parade them in my strip—not even really do anything with them—and in acknowledging them, make myself out to be a master satirist!
- The Monolith: They're like vermin, actually.
- No Fourth Wall: This comic doesn't just break it; this comic took the fourth wall out behind the shed and shot it. Then burned the body and snorted the ashes.
- Turned on its head during a storyline where Vaporware decides to rebuild the fourth wall, causing Chex and a bunch of characters from various self-referential franchises to try to stop him. He manages to defeat them all and rebuild the wall, only for things to return to normal shortly afterwards.
- Only Six Faces
- Perverse Sexual Lust: As it turns out, Dot owes most of her in-universe readership to this.
- Shameless Self-Promoter: Chex may very well be the patron saint of this trope.
- Straight Man: Lyle.
- Totally Radical: Do Chex's attempts to appeal to trendy teens all fail miserably? Right as ass they do.
- Tropes Are Not Good: Vaporware decides that his killing humans shtick is hacky and played-out, and that the only other narrative role available to robots—navel-gazing about his humanity or lack thereof—has also been done to death. He chooses neither, and becomes a farmer. (Nobody tell him that that's a trope too.)
- Unmoving Plaid: All over the place.
- You Mean Xmas: "X-Holiday".
Chex: Normally, whenever a strip runs out of ideas, it becomes self-referential.
Chex: I've been self-referential from the beginning.
Chex: I think I've been giving my readers the wrong impression.
Vaporware: I don't.
