An ogre, O, is a type of monster that appears in NetHack. It is a large, carnivorous humanoid with a single weapon attack.

Generation

Ogres may generate in small groups of two to four. They are generated with either a club (¹¹⁄₁₂ chance) or a battle-axe (¹⁄₁₂ chance), and can generate with offensive, defensive and miscellaneous items.

Ogres are the first quest monster for the Barbarian quest, composing 55% of the monsters randomly encountered there; they may also appear among the random O that make up 14% of randomly generated monsters and are placed at level creation on floors below the home level. Ogres are also generated on level creation for each floor of the quest: eleven on the home level, seven on the upper filler level, seventeen on the locate level, seven on the lower filler level(s), and sixteen on the goal level.

Strategy

Ogres are quite strong, but generally slow and can easily be picked off from a distance, especially with projectile weapons - characters without the AC or weaponry to try and best an ogre in melee combat may usually prefer this approach.

Encyclopedia entry

Anyone who has met a gluttonous, nude, angry ogre, will not
easily forget this encounter -- if he survives it at all.
Both male and female ogres can easily grow as tall as three
metres. Build and facial expressions would remind one of a
Neanderthal. Its small, pointy, keen teeth are striking.
Since ogres avoid direct sunlight, their ragged, unfurry
skin is as white as a sheet. They enjoy coating their body
with lard and usually wear nothing but a loin-cloth. An elf
would smell its rancid stench at ten metres distance.
Ogres are solitary creatures: very rarely one may encounter
a female with two or three young. They are the only real
carnivores among the humanoids, and its favourite meal is --
not surprisingly -- human flesh. They sometimes ally with
orcs or goblins, but only when they anticipate a good meaty
meal.
