His costume consists of a blue suit, with white shirt and red tie, hat, gloves and domino mask. Throughout the series he is seen in various states of undress, but he is never seen without the mask, aside from his very first adventure when he was still Denny Colt.
- Badass Normal
- Celibate Hero
- Clark Kenting: When he needs to be in disguise, The Spirit dons a pair of large dark glasses and no one notices the mask.
- He has, on other occasions, simply removed his mask (more common in the Darwyn Cook-helmed reboot) since very few people know or care who "Denny Colt" is thanks to being legally dead.
- Chick Magnet
- Coat, Hat, Mask: He IS a pulp hero after all.
- Deadpan Snarker: Definetly carries shades of this, especially in his solo adventures.
- Dating Catwoman: Touches on this with Sands Sareef and Silk Satin.
- Fedora of Asskicking
- Nice Guy: When not whaling on criminals, The Spirit comes off as the nicest guy in the world
- The Narrator: In the stories that he isnt the main character, The Spirit will often take the role of this.
- Lightning Bruiser: Can dish out and take a LOT of damage, despite essentially just being a brawler.
- James Bondage: Would often find himself tied up by his various opponents.
- Walking Shirtless Scene: Borders on this on occasion, especially during one series of stories where Spirit went off the grid in the Caribbean for a while.

- The Commissioner Gordon
- Cool Old Guy:
- Embarrassing Middle Name
- Secret Keeper: One of the few people who know that The Spirit is in fact Denny Colt.
Daughter of Commissioner Dolan and girlfriend of The Spirit. (Though not always according to The Spirit himself). When she was first introduced, she was an upright psychology student with big ol' Nerd Glasses; however, when The Spirit decided to take her glasses off and give her a big smooch, she became considerably less upright.
- The Not-Love Interest: Its on and off exactly how involved she and the Spirit are.
- She's Not My Girlfriend
Black kid sidekick to The Spirit and main provider of comic relief. (He was replaced later in the series by Sammy, a white boy, mainly due to concerns over racial stereotyping.)
As the Arch-nemesis of The Spirit, The Octopus appears more often than any other non-cast member. His face is never seen: it is either obscured or hidden by a disguise. He can always be recognized by his distinctive gloves. His origin would be told, not in the original strip, but in a story penned by Eisner for a comic reprint series put out in the 1960s collecting the old Spirit stories in traditional comic format.
Evil scientist who works with The Octopus.
- The Dragon: For the Octopus.
- Femme Fatale
- Hot Scientist: As she says in the movie, "I run a lucrative operation and I'm great eye candy." The fact that she's played by Scarlett Johansson doesn't hurt.
- Meganekko: Wears glasses.
- Only Sane Man: At least in the movie. Though considering the company she keeps is typically the Octopus and/or his cloned henchman, well...

Complete nobody who finds that he can fly.
