Del Lago is the first boss in Resident Evil 4. It is fought over the Lake in Chapter 1-3. During the boss fight, the player will have to control the boat that is simultaneously being pulled by Del Lago. Sometimes Del Lago will direct the boat so it will run into debris. The player's only weapon will be an infinite supply of Harpoons. After the battle, another cutscene will play where Del Lago sinks but the rope gets caught around Leon's ankle. The player must complete a quick time event to cut the rope and prevent Leon drop drowning and dying.
