Ogre

A staple of fantasy settings, the Ogre derives from various European lore relating to giants. Typically, ogres are the smallest, ugliest, dumbest and crudest of the variant giants; this justifies their frequent alliances with goblins and orcs due to a similar distaste for making an honest living and love of fighting. Generally, when your party is capable of killing orcs easily, ogres are the next step up.

Exactly just how crude they are varies from setting to setting. Pathfinder infamously made its ogres into inbred, cannibalistic, depraved rapist monsters straight out of some hicksploitation horror film. Picture a cross between The Hills Have Eyes and Deliverance played out by giants and you got the basic idea.

Dungeons & Dragons traditionally has a race called the Ogre Mage, which are smarter, more sophisticated ogres with a natural affinity for spellcasting. Really, these were cribbed from Japan, where its ogre-equivalent, the oni, invariably has magical powers of some kind. Only 4e and Pathfinder outright admitted that the Ogre Mage was just a D&D oni, though.

Warhammer has the Ogre Kingdoms.

In Warcraft Ogres are race of brutish barbarian like clans similar to the Orcs in Draenor. The Orc warlock Gul'dan developed two head Ogres to be slightly smarter than the average Ogre, he also made Ogre Magi who are smart enough to use magic.
