Dungeon Crawler Carl is an exciting book series that follows Carl and his (ex-girlfriend’s) cat Princess Donut as they navigate the Apocalypse. There are currently 8 books in the series—which means there are a lot of characters. We put together this guide to help you keep track of the characters while you’re reading or listening to the series, from the members of Carl and Donut’s party to their rival Crawlers and the Admin that run the Dungeon.

Note: There may be some minor spoilers ahead (but we really tried to avoid them because you should read the series).

1
Carl Carl is the main protagonist of Dungeon Crawler Carl. (You probably already guessed that.) He’s muscular, practical, and a former member of the Coast Guard. He survived the Apocalypse (or “Transformation”) that destroyed all human buildings because he went outside to get his ex-girlfriend’s cat, Princess Donut, who’d escaped through an open window.
- First appears in: Book 1, Chapter 0

Princess Donut Princess Donut is a tortoiseshell Persian show cat. Her full official name is “Grand Champion, Breed Winner Regional, National Winner Princess Donut the Queen Anne Chonk,” but Princess Donut will do. She’s the first cat to enter the Dungeon, and she gains the ability to talk. She’s the party leader of the Royal Court of Princess Donut (which she named, naturally) and one of the most popular stars on Dungeon Crawler World.
- First appears in: Book 1, Chapter 1
- Fun fact: The narrator of the Dungeon Crawler Carl audiobooks, Jeff Hays, has been cast as the voice of Princess Donut in the upcoming live-action adaptation!^{[1]

Prepotente (“Pony”) Prepotente—or Pony, as Carl usually refers to him—is a goat from Italy. He became a Caprid (a sapient, bipedal goat race) after eating an enchanted pet biscuit given to him by his owner, Miriam. He quickly became a powerful fighter, eventually joining Carl and Donut’s party.

Katia Grim Katia joins Carl and Donut’s party on the third floor. She’s originally an art professor from Iceland, but she chooses to become a shape-shifting doppelganger. She’s a tanky character, but she starts out timid, weak, and inexperienced. Her character arc is one of the most emotional in the series.^{[4]
