Dr. Potter

Dr. Potter is the seventh boss encountered in Luigi's Mansion 3. He is encountered and fought on Floor 7 after Luigi locates him at the greenhouse. Defeating Dr. Potter rewards Luigi with the elevator button to the eighth floor.

Appearance

Luigi finds the eighth floor button seemingly unguarded, although before he can fully celebrate, he finds a watering can that causes a sapling to grow into a venus flytrap, with Luigi accidentally feeding the button to the flytrap out of shock. Dr. Potter then reveals himself and taunts Luigi before watering more nutrients to the flytrap, causing it to become gargantuan in size. He then flees, although not before laughing one last time at Luigi.

After Luigi gets the button out of the venus flytrap (and is forced to backtrack back down to stable ground after dropping it to the ground), Dr. Potter then intercepts the button with a Venus Flytrap of his own and then confronts Luigi, although Dr. Potter unintentionally has his flytrap expose a buzzsaw.

Battle

Dr. Potter mainly relies on his venus flytrap's various lunges as its attacks.

To beat Dr. Potter, the player has to bait Dr. Potter's flytrap into attacking a stub and getting itself stuck on it. Afterwards, the player needs to grab the buzzsaw and cut the plant off at the stem. Afterwards, flash Dr. Potter and then suck him in. After expending all his HP, he'll humorously try to first escape from, then get his beard caught in and then (unsuccessfully) attempt to get it unstuck from the suction, resulting in his capture.
