An Ogre is a large humanoid creature in the Warhammer Fantasy fictional universe. They are based on the ogres of mythology.
Prior to the release in 2005 of Warhammer Armies: Ogre Kingdoms for Warhammer Fantasy Battles tabletop game Ogres appeared only as mercenaries or Auxiliaries to other armies. The Ogre Kingdoms book expanded the history and character of the Ogres and they can now be fielded as a single army of their own, although the option to use them as mercenaries in other armies remained. However, the option to field allies or use mercenaries in general has since been dropped from the core Warhammer rules, with the discontinuing of the Dogs of War and the Regiments of Renown. Furthermore, the release of the Ogre Kingdoms Army Book itself was controversial, as one already existing army, Wood Elves, had yet to be released at that time.
