I don't have a lot of time to post this week; I've been helping my girlfriend move house and haven't had much time to spare for working on D&D materials. But in compiling my notes for OD&D, I'm always struck by how many monster are included in the original game. Not just the ones given stats in Vol. 2: Monsters & Treasure, but the ones mentioned in passing, and those listed in the wandering monster tables. Many of those aren't given stats in OD&D, so if I'm going to build a version of the game using only 1974 materials I'll need to stat them all up. I'm going to list all of the monsters in OD&D below, with some notes about where I might find stats for them.
Monsters Fully Stated in Vol. 2
Like it says, these are the monsters given full entries and stats in OD&D. I've included Hobbits here, even though they don't get a monster entry, because they're fairly well detailed in Vol. 1.

Monsters Described But Not Detailed in Vol. 2
This selection of monsters is given as an example of how the monster list can be expanded. Gelatinous cubes, golems, salamanders and titans will be given stats in Supplement I: Greyhawk. Androids and robots are both given as more general categories, and neither make it into core D&D, though I suspect that there are examples in specific adventures (particularly Expedition to the Barrier Peaks). The Juggernaut is in Tomb of Horrors. Living statues will be given stats in the Moldvay Basic Set, although the example detailed here is an iron golem. I'm not sure about the Cyclops. It doesn't get stats in the Monster Manual, but surely it's detailed at some point. Maybe in Supplement IV: Gods, Demigods and Heroes? Regardless, I'll have to come up with stats for most of these that are in line with OD&D.
- Android
- Cyclops
- Gelatinous Cube
- Golem
- Juggernaut
- Living Statue
- Robot
- Salamander
- Titan
Monsters Given Stats in the Naval Combat Section:
All of these creatures are given basic stats, and simply have to be fleshed out a bit.
- Crab, Giant
- Crocodile
- Crocodile, Giant
- Dragon Turtle
- Fish, Giant
- Leech, Giant
- Octopus, Giant
- Sea Snake, Giant
- Squid, Giant
Martian Creatures Mentioned in the Wilderness Wandering Monster Tables:
These monsters are all drawn from Edgar Rice Burroughs' Barsoom novels. They aren't given stats in OD&D, but their details can be extrapolated from TSR's Warriors of Mars which was published not too long after.
- Ape, White
- Apt
- Banth
- Calot
- Darseen
- Martian
- Black
- Red
- White
- Yellow
- Orluk
- Sith
- Thark
- Thoat
Other Monsters from the Dungeon and Wilderness Wandering Monster Tables
These creatures are all mentioned as wandering monsters, but given no stats at all. The entries for Insects (small and large) and Animals (small and large) can be used as a basic guideline. Most of these creatures will be detailed in the AD&D Monster Manual, but will have to be given stats in line with OD&D.
- Ant, Giant
- Ape
- Bear, Cave
- Beetle, Giant
- Boar, Giant
- Brontosaurus

- Lion
- Lion, Spotted

- Mammoth
- Mastodon
- Pterodactyl
- Rat, Giant
- Rhinoceros, Woolly
- Scorpion, Giant
- Shadow
- Snake, Giant
- Spider, Giant
- Stegosaurus
- Tiger, Sabre-tooth
- Titanothere
- Toad, Giant
- Triceratops
- Tyrannosaurus Rex
- Weasel, Giant
- Wolf, Dire
Some Others Mentioned in Monster Entries as Pets
There are monsters that keep other creatures as pets, or can summon creatures to fight for them. None of these pets/summoned animals are given stats.
- Bat
- Bear
- Fish:
- Gar
- Muskie
- Pike
- Rat
- Tiger
- Wolf
I believe that's a comprehensive list of the monsters mentioned in original D&D. I've already given stats to most of them, converting their abilities and damage ranges to fit with OD&D's lower scale. I will probably post them over the coming weeks, unless some other topics take my fancy.
