Ornlu the Wolf appears as a regular wolf. Has tremendous attack power and hp comparable to William Wallace, but lacks any attack bonuses and takes damage bonuses against most units. Still, Ornlu is strong enough to compete with many regular units as well as some hero units. Ornlu is available in the custom scenario creator in both Age of Empires II: Age of Kings and Age of Empires II: The Conquerors
Ornlu the Wolf appears during the first Genghis Khan campaign, "Crucible", as an ominous threat that the player must kill in order to recruit the Uighur clan. Accompanied by a pack of dire wolves and hunting wolves, the path leading to Ornlu's location is littered with skeletons. Winning the Uighur clan's allegiance yields camels and the Chemistry technology for the player to use during the rest of the campaign.
Ornlu also makes an appearance in the The Conquerors expansion during Montezuma's campaign, fourth mission "La Noche Triste", guarding a small island of gold mines alongside a pack of jaguars.
