The Tyrant, or Mr. X, is a relentless pursuer throughout the RPD and beyond. While not a traditional boss fight in most encounters, there are specific moments where you must defeat him. He is immune to most small arms fire. His weak point is his head. For Leon, the Shotgun or Magnum are your best bets. For Claire, the Grenade Launcher with Explosive Rounds or the Spark Shot can deal significant damage. During the final encounter, you'll need to damage him enough until a specific weapon (the Rocket Launcher) becomes available. Keep moving, avoid his powerful punches, and aim for the head. He will be temporarily stunned after taking enough damage, providing an opening.
