The Heroes
The world's greatest Occult Detective and opponent of the Cthulhu Cycle Deities. He is the protagonist for the short stories and the first two books in the series.

- The Bus Came Back: With Elysia's destruction, is now wandering around the universe with Henri.
- Awesomeness by Analysis: Is able to figure out the entirety of the Chthonians plot by analyzing newspapers and some Pulp fiction.

- Badass Longcoat: As displayed on the original The Compleat Crow collection.
- Battle Couple: Forms one of these with Tianna the Girl Goddess.
- Bunny-Ears Lawyer: Compared to other Lovecraft protagonists as he reacts to the existence of the Mythos with fascination more than stunned terror.
- Crazy-Prepared: Titus Crow once regularly downed a magic potion, cast daily spells, and lived on a houseboat to avoid the Chthornians. This proved insufficient.
- Cyborg: Becomes one of these after an alien robot rebuild his body.
- Doctor Whomage: Crow has been compared to The Doctor due to travelling through time and space in the Bigger on the Inside De Marigny's Clock.

- Gentleman and a Scholar: A genius scholar of the occult as well as an English gentleman.
- Gentleman Wizard: Starts the book series as a combination of this and Occult Detective.

Cthulhu Cycle Deities
Leader of the Chthonians: race of worm-like monsters with a squid-like head. Shudde M'ell appears like a larger form of a Chthonian, and possibly the progenitor of the species.
- Broke Your Arm Punching Out Cthulhu: While the Wilmarth Foundation managed to wipe out many Chthonians, they lost a lot of people and resources. Also occurred when they tried nuking Shudde M'ell himself, and failed.
- Eyeless Face: Chthonians in general have no eyes.
- Nigh-Invulnerability: Shudde M'ell can take on a nuclear explosion and live, as well as able to bore through Earth's crust and survive in the planet's mantle.
- Made of Iron: Cthonians are able to resist great pressures and temperatures.
- Mama Bear / Papa Wolf: Generally, it’s a bad idea to mess around with Chthonian eggs.
- Mental Fusion: Groups of Cthonians can combine their psychic powers to overcome any protection.
- Psychic Link: All Chthonians are linked to each other, allowing to know exactly what other one knows.
- Sandworm: Chthonian physical appearance suggests this, but they're more like the Horta from Star Trek. They can easily burrow through rocks, and can resist high pressure and heat. Although, the Cthonians and Sandworms do share the same...
- Weaksauce Weakness: Chthonians don't take well to exposure to, of all things, water. Which helps explain why they usually tend to stay safely miles underground rather than visit Earth's mostly water-covered surface, of course.
- Telepathy: The worms can influence a person's thoughts and emotions, causing them to make mistakes or force them to stay in one location.
- Tome of Eldritch Lore: The G'harne Fragments, which tell of the history of the titular Cthonian city.
- Tunnel King: Chthonians excel at this.
