Monster Manual
A Monster Manual (sometimes called a Monstrous Manual or a Bestiary) is a book (or set of pages you can put in a binder if you are a particularly crusty neckbeard) used in RPGs to describe the various kinds of monsters the PCs can encounter and fight. The Manual is intended for DMs to make encounters for the players. Though they are more often described in the DMG, these books can also contain descriptions for the more exotic kind of trap (no not like that). Some books may also include templates to apply to existing monsters to change them (read: make them deadlier) or ways to make your very own monster from the ground up.
If they are not bundled into the main manual, a new release of a game can see a new Monster Manual as well. This first Monster Manual is seen as a "core book" in the trinity of the Manual, the Handbook and the holy Guide. There have been times when the first monster manual preceded the rest of the core: this notably happened in 1977, so its Manual was compatible with the ancient rules that became BXCMI, up to which the AD&D Dungeon Masters Guide had to catch. This also happened in 3e/d20 with Sword and Sorcery Studios' rushed-to-print Creature Collection, and with Violet Dawn's Denizens of Avadnu. If ever comes that published setting at all, as Eden's Liber Bestarius.
After the first Monster Manual of an edition the follow-up books are divided into two different camps. One is the list of Monster Manuals who will be named Monster Manual II, Monster Manual III and so on. The other are the more "themed" books that describe settings for adventures and monsters that fit in those settings, like books describing the Underdark having many Drow, spider and Aberration type enemies, or The Manual of the Planes describing Fiends like Tanar'ri and Baatezu, alongside creatures of Chaos like the Githzerai and creatures of Law like Modrons. Books in the latter category are not considered Monster Manuals despite their number of described creatures.
Then there are the "B Side Collections"... In the early 1980s TSR found itself with dozens of post-Manual monsters from early adventure-modules and especially from another country - Great Britain, in White Dwarf magazine. Gygax bundled the former with the best he could scrounge from the latter, birthing - or, perhaps, pinching off - the Fiend Folio. After this one's mixed reception, "fiend folio" is now a term for a holding-pen of niche monsters which you don't want defiling the mainline of Manual sequelae.
The problem with making a lot of Monster Manuals is that the monsters in the later books are split up into four groups: 30% will be reprints of monsters from older books of varying obscurity, 30% will be either upscaled animals or creatures made by slapping a number of templates together ending with creatures that lack the focus and originality of their progenitors, 30% will be 'Folio-bait (Three-headed hermaphrodites! Killer paper! Murderous hats!), and the final 10% being actually interesting creatures (either original or mythological) that could make an interesting addition to a game.
Theoretically the game can be played without the Monster Manual and just the PHB+DMG by making human(oid)s and traps the only enemies. In practice this is never done for long and the Monster Manual is an important part of any game, as a game with nothing interesting to fight is just as bad as uninteresting mechanics or classes.
The only two editions after AD&D to not start with a Monster Manual are 2nd Edition, which instead had the Monstrous Compendium series which were released in loose-leaf form instead of as books before they later released the Monstrous Manual, and 4th Edition Essentials, which instead had the short-lived Monster Vault series. Those ideas went down like Monica on the Hindenberg against the Washington Monument.

Monster Manual (AD&D)
The basic monsters were the monsters which the English Speaking Peoples [TM, Churchill] grew up with, from such stories as Gary Gygax read in his childhood - which was a long time ago. (Note that E.G.G. was a "coot" even in Dave Arneson's eyes in the early 1970s.) You will see a lot of Europe in here, from Grimm and Greece. Where the critters aren't European - like the djinn - they are from Victorian-era translations of Egyptian and Syrian work. The most truly exotic here are the demons; perhaps as they should be.

Monster Manual II (AD&D)
The Fiend Folio was deemed a failure to which end TSR's marketing geniuses figured out its MAIN problem... branding. So here we got the third Manual sold to us as the second. As the Folio passed along 1970s-era monsters (and a lot of shit from the Fiend Factory), this "second" Manual packaged up early 80s monsters from the S- series and the A- series (alongside some shit from Dragon). The illustrations are better than Folio's grainy and gory horrors. The font is still awful, so a generation of gamers never did figure out if the orangutan demon was a bar-lgura or a bar-igura.
- Aboleth
- Afanc
- Agathion: A good spirit from the upper planes that can take the form other good-aligned creatures or an incorporeal spirit bound to an item. In its natural form it resembles an elf with shining eyes. They have both psionic abilities and some of the powers of a Cleric and can cause positive energy damage with a touch in their natural form. In later editions it was renamed to Agathinon. The original name was recycled by Pathfinder for their version of the Guardinal.
- Annis
- Ant Lion: A giant antlion, an insect whose larva dig pits to trap prey.
- Ascomoid
- Aspis
- Drone
- Larva
- Cow
- Atomie
- Aurumvorax
- Azer
- Baku: A tapir-like creature from Japanese mythology that consumes dreams. This version of the Baku does not eat dreams. It is a good-aligned monster with stone psionic abilities as well as being able to gore and trample enemies, and it also has a trumpeting roar that damages and frightens evil creatures.
- Banderlog: An intelligent baboon-like primate.
- Barghest
- Barkburr: An animated plant that disguises itself as a burr on a tree. It jumps on people that it sees as a threat to the forest where it lives and injects them with a poison that turns the victim into a tree, which may stay a tree, or morph into a badger, a giant weasel, a Treant, or a level 1 Druid.
- Direburr: A variant of the Barkburr that attacks people indiscriminately and only turns victims into lifeless trees.
- Basidirond
- Greater Basilisk
- Bat
- Mobat: A giant predatory bat with a painful shriek that forces people to cover their ears instead of fighting.
- Ordinary Bat
- Fire Bat: A bat from the elemental plane of fire. They can burn people and drink their blood at the same time.
- Northern Bear (Polar Bear)
- Giant Bee
- Worker Honeybee
- Soldier Honeybee
- Bumblebee
- Beetle
- Death Watch Beetle: A monstrous beetle that camouflages itself with bits of debris glued to its back and has the ability to produce a sound that can instantly kill nearby creatures.
- Slicer Beetle: A beetle that hunts by cutting a victim's arm or leg off and then running away with it. Its lair may contain mismatched pairs of magic gauntlets or boots from its victims and the book has rules for what happens if you wear a mismatch pair of boots or gauntlets.
- Behemoth: A bigger and meaner version of a hippo.
- Behir
- Bloodthorn
- Boalisk: A constrictor snake that also has a gaze attack that inflicts a rotting disease.
- Bodak
- Boggart: The immature form of a Will-o-Whisp that looks like a humanoid.
- Boggle: Ugly humanoids that secrete a slippery oil and can cast dimension door through anything that vaguely resembles a door frame to a place only up to three feet away.
- Boobrie: A massive marsh-dwelling bird.

From 1984 on, Dragon Magazine published dozens of new monsters in three Creature Catalogs. These didn't make it into officially-bound texts at the time, but the Lillend and the Dark Naga will find some love in the next edition. You might consider the monsters in these three to amount to a Fiend Folio II.
Monstrous Manual (AD&D 2E)
This was an odd duck in the series, because post-Gygax TSR got it into its head that we didn't need no stinkin' manual. Their rationale was that every setting should differ, and where an Athas might not have orcs (anymore) another locale might be like Talislanta and short on elves. Even if they did have something called an "elf" it will be setting-specific. So they released "Monstrous Compendium" sheafs, each monster to fill two sides of a page, which the DM could put into a binder or a Trapper Keeper or something.
As usual, early 1990s TSR had failed to listen to their actual customers, lost demon-worshipping souls as we are. It turns out that plenty of settings agree on the same basic monsters, or at least like to leaf through the pages for inspiration. So, kicking and screaming, in 1993 TSR released the Monstrous Manual. It followed the same monster-to-a-page format, so you could detach these ladies and fill your binders with them as the Prophets demand.
