Premise
The series begins with the sudden arrival of alien entities known as the Borant Corporation, who restructure Earth into a multi-level dungeon for their game show. Humans and various Earth creatures are forced to become "contestants" in a live-streamed, gladiatorial game show, ''Dungeon Crawler World''. Carl, having just been cheated on by his girlfriend and left with her cat, Princess Donut, finds himself thrust into a deadly competition with uncountable viewers across the galaxy watching their every move. Early in the first novel Princess Donut becomes able to communicate with humans due to a special pet biscuit that Carl received for bringing the first cat into the dungeon. The biscuit also enhances Princess Donut's base stats, causing the dungeon to view her as the leader of her and Carl's two person group, which she dubs the "Royal Court of Princess Donut". As the series continues Carl encounters several other dungeon crawlers that include Frank Q and Maggie My, who have targeted Carl out of revenge. Other characters include Samantha, a banished lesser deity who inhabits the severed head of a love doll and who joins the Royal Court.
The dungeon levels are filled with traps, puzzles and monstrous creatures, all designed to test the contestants' strength, cunning, and teamwork. As Carl progresses through the dungeon, he gains experience, levels up, and acquires new skills and equipment, typical of LitRPG stories. Carl also learns that there is an ongoing power struggle between the corporations that run the various seasons of ''Dungeon Crawler World'', which has caused the Borant Corporation to speed up the competition in order to stave off its competition from acquiring it.
The series is known for its dark humor, over-the-top violence, and the unlikely but endearing partnership between Carl and Princess Donut.
Development

Dinniman began writing ''Dungeon Crawler Carl'' in December 2019 and started publishing the series on Royal Road. Due to the series' popularity, he began self-publishing the series on Amazon in 2020.
While writing the series, Dinniman drew upon his experience playing MMOs such as ''

'', as well as the concept of in-game chatting, which he noted "adds another element because there’s all these different dynamics happening at once."
Prior to writing the series Dinniman espoused a desire to write a novel with a death-game setting; he also wanted to include a tortoiseshell-colored Persian cat after seeing one at a cat show, where he was working as an artist. Per the author, he did not initially plan for the cat to be sapient and that this developed as Dinniman continued the series, as he tends to create and embellish the story as he works. This eventually led to the creation of Princess Donut as she is presented in the series, a character that Dinniman has stated is vital to the series. Dinniman is known for his interaction with his fanbase and allows his

subscribers to impact some limited elements of the story by voting on the outcome of external factors such as lootbox content.
The series includes some dark and comedic elements. In an interview with ''Grimdark Magazine'' Dinniman stated that it was difficult to maintain the balance between these two elements and that rather than automatically write a comedic scene after each dark one, he instead relies "on the characters themselves to get from point A to B, and humor is oftentimes a major coping mechanism."
Dinniman initially kept track of the series' characters and storylines via a spreadsheet that grew up to 198 pages, requiring the use of a second spreadsheet to track the content on the first. The size of the spreadsheet eventually crashed Dinniman's computer, causing the author to hire someone to create a
Notion database for better ease of use.
In 2024 Dinniman stated that he planned for the series to span ten books, but that "nothing is set in stone".

Audiobooks
The main audiobook adaptations of the Dungeon Crawler Carl series have been narrated by Jeff Hays, who has produced the adaptations via his company Soundbooth Theater. Dinniman has stated that Hays's narration of female characters is so convincing that he has had people ask him if Annie Ellicott, a Soundbooth Theater artist, was an uncredited narrator for the first book.
Some guest narrators have appeared on the audiobooks, such as
Travis Baldree and
