Steward (Luigi's Mansion 3)

The Steward is the first boss encountered in Luigi's Mansion 3. He is first encountered normally on the first floor of the Grand Lobby and is subsequently fought in the Garage in the Basement after Luigi frees Professor E. Gadd. Defeating the Steward rewards Luigi with the elevator buttons to the first and fifth floors and allows E. Gadd to set up his lab in the Garage.

Appearance
When initially seen in the Grand Lobby, the Steward wears a mask and an oversized coat and sits at the reception desk. If spoken to, he will ask Luigi if he and his company are ready to check in. Obliging to the request prompts Hellen Gravely to lead the group to the fifth floor.

The Steward is encountered again in the Garage, trying to wheel a cart containing his mask and coat. When he spots Luigi, he becomes visibly shocked and pushes the cart away. He then begins picking up suitcases to throw at Luigi.

Battle
The Steward's only attack involves lugging suitcases to throw at Luigi. He becomes vulnerable after throwing a suitcase, and can be attacked after using the Strobulb on him. His attack can be interrupted by using Burst, and his attack will be neutralized if the suitcase hits a ceiling light.

Once the Steward loses all of his HP, he begins struggling to break free from the Poltergust G-00, only for him to be sucked in and his hat to comically fly off, of which he then pulls in.

Trivia

 * Steward is the only boss ghost in the game to possess two elevator buttons rather than just one.
