- Back from the Dead: Considering how inept Deaths are, this is common.
The creator of the comic himself has his own theme, usually revolving around working on the comic, his everyday life, his being on the run from Death...
This theme is mainly a spoof of Indiana Jones.
The Jones family
Montana (Monty) Jones
The main character of this theme. An Archaeology professor who constantly needs to fight against the Nazis to take control of powerful artifacts that the Nazis will use to conquer the world. Hates wurst.
- Embarrassing First Name: His birth name was North Dakota Jones Junior. He prefers Montana.
- No Respect Guy
- Whip It Good: Occasionally use whips.
Prof. North Dakota Jones
Monty's father. Obsessed with the Holy Grail.
Minnesota JonesNorth Dakota's father, thus Monty's grandfather. Was presumably lost after he went on dinosaur chasing.

Monty's archnemesis. Hitler-brain-in-a-jar's primary lackey when it comes to gathering powerful artifacts.
- Even Evil Has Standards: He may be a Nazi, but he enlisted to collect various Artifacts of Doom and is completely disgusted by genocide.

- The Millstone: When he was petrified, Hitler took over Europe easily.
- Obviously Evil: Let's see... Dueling Scar, Hook Hand, stereotypical "bad-guy" mustache, and a Nazi to boot.
Haken's main lackey. Is not really as committed to the Nazi principle as others, thus is a bit more reasonable.
Hitler's Brain in a Jar. Need I say more? Anyway, he died in the Reichstag fire and his brain was put on life support by Adam Savage to win a Bet With Death. Plans to take control of powerful artifacts and take over the world.
- Brain in a Jar: Natch.
- Dark Lord on Life Support: Hitler was burnt at the Reichstag fire and is a brain in a jar.
- Ghostapo: Is obsessed with occult.
- Real Life Writes the Plot: Part of the reason that he's a Brain in a Jar is because Lego, for obvious reasons, does not make Hitler minifigs.
- Stupid Jetpack Hitler: Complete with multiple clones of his own brain.
- Take Over the World
The Jones family's Arabic friend who will always come to their rescue.
- Big Damn Heroes / Deus ex Machina: Want to be rescued? Bet on him! Once inverted though.

- Odd Job Gods: Most of them watch over a very specific (and often very unlikely) aspect of death.
Death of Insanely Overpowered Fireballs

- Butt-Monkey: Gets who get job shuffling the most?
- Ensemble Dark Horse: Really popular.
- George Jetson Job Security
- Reassignment Backfire: He could lead the Deaths' Strike without being drawn to do his job because at that point, he had been demoted to Fate Worse Than Death, and as such was no longer a Death. The Head Death ends up breaking the strike by rehiring him as Death of Insanely Overpowered Fireballs.
- Sinister Scythe: He uses one, made by cutting one blade off a lego pickax.
Death of Choking On A Giant Frog
Fireballs's competitor, since he wanted to be Death of Insanely Overpowered Fireballs, but otherwise friendly to each other. Apparently he originally died when an aide of his shoved a giant frog down his throat.
The boss. He is in charge of the Deaths' positions, and will demote and promote the lesser Deaths based on their performance. Really hates the Paradox Department.

- Quintessential British Gentleman
- Wild Mass Guessing: Is Lewis Carroll from Scientific Revolution. Maybe.
- Yank the Dog's Chain: He finally gets to collect the Mythbusters, but they get sent back to the land of the living.

Your old stereotypical dwarf with Scottish accent. Got persuaded to join the group by Kyrosâi, by predictable method.

- Nice Hat: A red one that somewhat resembles a fez.
- Rat Men: He appears to be a sci-fi variant.
The ship's pilot. Was dead for a while.
- Death Is Cheap: Constantly subverted. She could come back via cloning, but her crewmates keep accidentally screwing up her chances. She eventually comes back as a ghost, and then is brought back to life when the universe is destroyed and then recreated.
- Gender-Blender Name: In the campaign the Space theme was based on, Paris's player intended her to be male (and named after Paris of Troy), but everyone else assumed her to be female, and the player went with it.
- Our Ghosts Are Different: As a ghost, she was partially transparent, insubstantial, and glowed in the dark. She could interface with the ship's controls to pilot it.

Steve's wife and voice of reason.
- Only Sane Man: to Steve.
"Mighty Cthulhu is one of the Great Old Ones, an Elder God who lies in eternal deathless sleep in the sunken nightmare city of R'lyeh.

- Eldritch Abomination
- Mix-and-Match Critter: How he was put together.
- Revenge: Wants revenge against Steve for killing him several times.

The last 3 Martians who still plans to conquer Earth, but pretty inept at it.

Owner of a local pizza place where Ishmael works.
