In the Dungeons & Dragons role-playing game, ogres are a lesser race of giants, rather being simply large brutes with clubs. An aquatic subrace of ogres is known as "merrow." D&D ogres are also closely related to the race of ogre magi, a smarter race with blue skin and great magical abilities. It is unclear if ogres and ogre magi are actually the same race, or if ogre magi simply find lesser ogres easy to boss around. Typically Ogres stand between nine and ten feet tall and can weigh up to 650lbs. Ogres are closely related to trolls, and are distantly related to the various races of giants.
