In Monsters, Inc., what is the name of the company’s CEO at the start of the film?

In Monsters, Inc., the company’s CEO at the start of the film is Henry J. Waternoose III.

Waternoose is the crab-like monster who leads Monsters, Incorporated during the film’s opening. He is closely associated with Sulley’s career and presents himself as a veteran executive responsible for protecting the company and Monstropolis from an energy crisis.

His full name includes the suffix “III,” identifying him as the third Waternoose in his family. The name is often shortened in discussion to Mr. Waternoose or simply Waternoose, but the formal character name is Henry J. Waternoose III.

Waternoose later becomes involved in the plan to use a scream extractor, a machine intended to obtain screams from children more efficiently. The plan is exposed, and Waternoose is removed from leadership. Roz, whose identity is connected to the CDA, helps reveal the wider investigation.
