He was introduced in the Age of Kings and only personally appears in the The Emperor Sleeping scenario of the Barbarossa campaign. He also appears as an enemy player in The Lion and the Demon scenario of the Saladin campaign.
In The Forgotten, he appears again as a controllable and must-survive hero in the scenario Cyprus, under the Battles of the Forgotten campaign, which depicts Richard's adventures prior to his arrival at the Holy Land for the Third Crusade.
He is also available in the Scenario Editor.
In-game, he has the appearance of a Paladin. Like other cavalry heroes, Richard the Lionheart is affected by all upgrades and bonuses that affect cavalry. As a hero, he cannot be converted and can regenerate health (since The Conquerors).
