Ogres in Heroscape refer to a total of three different species, the Pulverizer from Toril, the Warhulk from Eberron, and Gurei-Oni from Feylund.
Toril Ogres: Aggressive, strong, and dull-witted, ogres are the quintessential big, dumb brutes. Many creatures (particularly orcs) take advantage of ogres and convince the monsters to work for them. The stupidity of ogres is legendary. Few ogres can count to ten or build even the simplest tool or shelter, so they generally lair in caves or ruins and fight with clubs made from tree trunks. Some ogres know a few words of Common, such as “gold,” “kill,” and “mine!” Ogres are cruel, bloodthirsty, greedy, and gluttonous; they can be easily bribed with gifts of food and treasure, as long as their would-be allies or masters can promise them plenty of opportunities for mayhem and destruction.
