Crawler profile
Lucia Mar. A 13-year-old crawler from South America who arrives in Book 1 as one of Carl and Donut's fiercest rivals. Race: Lajabless. Class: Black Inquisitor General.

Who is Lucia?

Lucia Mar is one of the crawlers Carl and Donut run into early, and she is not on their side. She is young, she is dangerous, and she does not back down. Her race and class come with the Floor 3 selection in Book 2.

What happens with Lucia after that is a spoiler for later books. If you are caught up, the recaps cover it book by book, with full spoilers.

Lucia Mar: questions readers ask

How old is Lucia Mar in Dungeon Crawler Carl?

In Dungeon Crawler Carl, Lucia Mar is about 13 years old. That is Carl's own estimate when the show first features her in Book 1, a kid in an oversized yellow soccer jersey with a thick blue stripe whose two rottweilers tear apart a cow-sized spider. Carl guesses from her look that she is from South America; the book never gives an exact age.

She does not stay looking 13 for long: the race she picks on Floor 3 in Book 2 gives her the body of an adult woman, which is why later descriptions of her read so differently.

What are Lucia Mar's race and class in Dungeon Crawler Carl?

In Dungeon Crawler Carl, Lucia Mar picks the Lajabless race and the Black Inquisitor General class on Floor 3 (Book 2). The class combines cleric, magic-user and warrior. The race splits her day in two: half as a beautiful woman with doubled magic and halved strength, half with a skull face, doubled strength and costlier spells. Her right leg also becomes a goat's leg with a cloven hoof.

The name comes from La Diablesse of Caribbean folklore. Carl's own Floor 3 pick is on Carl's page.

Does Lucia Mar join Carl and Donut in Dungeon Crawler Carl?

In Dungeon Crawler Carl, the feud starts at the Desperado Club in Book 2. Lucia's dogs kill two attendants and another pet, her membership is revoked, and a drunk Princess Donut insults the dogs. A news show frames the insult as a challenge.

Lucia turns down a staged fight on the arena show Knuckle Cracking and vows instead to kill Donut inside the dungeon, then Carl. So through Book 2 she is no ally of theirs. How the rivalry develops after that is a later-book spoiler. The floor where it starts is in the Floor 3 guide (Books 2 and 3).

Steve H. FIXED

Lucia Mar’s character page is grossly missing her antagonistic role in the first four books.

Correct, and worse than reported: her page said she first appears in Book 5 and called her a party member. She arrives in Book 1 as a rival. Corrected 2026-09-06.
