Ogre in The Blue Crystal Rod

Ogre (オーガ) is a large humanoid monster with one eye armed with a trident.

In The Quest of Ki, Ogres are stationary enemies like the Vampires. The player loses one life if Ki touch an Ogre, and they won't disappear if it happens. They can be removed from the room by taking the treasure box with a orb.

In The Blue Crystal Rod, Ogres are one of the random enemies that appear in the Cave of Elburz. Also, one Ogre can be seen when The Quest of Ki is shown in the introduction of the game.

Ogres also appear in Seme COM Dungeon: Drururuaga and in the anime The Tower of Druaga: The Aegis of Uruk.
