Mr. Waternoose’s first name is Henry in Pixar’s Monsters, Inc.
Henry J. Waternoose III is the CEO of Monsters, Incorporated at the beginning of the film. He is a large crab-like monster and represents the company’s established leadership as it struggles with declining energy from children’s screams.
Waternoose presents himself as a longtime member of the company’s history and emphasizes the importance of protecting its operations. His relationship with Sulley is initially supportive because Sulley is the company’s most successful scarer.
The character’s full name includes the generational suffix “III,” identifying him as Henry Waternoose the third. Viewers sometimes remember only “Mr. Waternoose” or confuse his first name with the names of other executives in animated films. The film’s plot later reveals that he is involved in a plan to preserve the company’s power supply through forced scream extraction.
