The Monster Manual II along with the First Edition Unearthed Arcana book featured quite a number of monsters, races, and places from Gary Gygax's Greyhawk Campaign world. Like the Fiend Folio before it, the monsters in Monster Manual II listed the experience point value for each monster within the entry. The book included random encounter tables for dungeon and wilderness settings built from the Monster Manual, Fiend Folio, and Monster Manual II, and a dozen new devils that had been first published in the pages of Dragon magazine. Many of the monsters were drawn from scenario modules, in particular from S4: Lost Caverns of Tsojcanth.

The book was a supplement describing over 250 monsters, most with illustrations. Monster Manual II was a 160-page hardcover book published in 1983, credited solely to Gary Gygax, which featured cover art by Jeff Easley.
