- 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.

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.
- Arch-Enemy: To The Spirit
- The Faceless: His face is not seen once in the entire comics run. Averted in the movie, in which Samuel L. Jackson plays him.
- Iconic Item: The Octopus can always be identified by his striped gloves.
- Stealthy Cephalopod: Invoked. He uses the octopus as his namesake, and always hides his appearance with obscuring clothes or by staying just outside the panels.
Crime lord with a "black widow" m.o. who often tries to seduce The Spirit.
