Luigi: Difference between revisions

*In the original ''Luigi's Mansion'', Luigi is informed that he had won a mansion in a contest he never actually entered. Prior to his arrival, Mario was observed entering the mansion by the elderly ghost researcher Professor Elvin Gadd, or E. Gadd for short, but never returned. Upon his arrival at the mansion, Luigi realizes his brother is nowhere to be found and is nearly captured by an orange ghost before being saved by E. Gadd. The professor escorts Luigi to his laboratory near the mansion and offers him a crash course in using the Game Boy Horror and Poltergust 3000, a modified vacuum cleaner capable of sucking up ghosts and other objects. With his Poltergust in tow, Luigi musters the courage to re-enter the mansion to find his missing brother. Upon delving deeper into the mansion, Luigi unwillingly unleashes a wave of captured Boos, including their leader King Boo, and must reclaim them before being able to face the king himself. On his way to recapture the Boos, Luigi discovers that King Boo has actually captured Mario and trapped him in a painting. In the final confrontation, the king attempts to stop Luigi using a lifelike Bowser costume, though Luigi ultimately succeeds in capturing King Boo and rescuing his captured brother, freeing him from his painting prison.

*In ''Luigi's Mansion: Dark Moon'', E. Gadd takes his studies to a new venue, Evershade Valley, and makes peace with various friendly ghosts in the area to assist in his research. Unbeknownst to anyone, King Boo managed to escape his portrait prison and shatters the titular Dark Moon, a large floating crystal that normally has a pacifying effect on the ghosts of Evershade Valley. With the Dark Moon destroyed, the friendly ghosts turn hostile and start causing chaos, prompting E. Gadd to retreat and recruit Luigi to help recover the shattered fragments. Along the way, Luigi acquires some new tools to his new Poltergust 5000, including the Dual Scream, Strobulb, and the Dark Light, as he travels to five distinct mansions to recover the Dark Moon fragments. Along the way he and E. Gadd discover that Mario has been captured in a painting again, and in one final illusion he confronts King Boo and succeeds in defeating him in his illusion. With Mario saved and the Dark Moon restored, the ghosts become friendly again and Luigi returns home with a new pet Polterpup in tow.

*In ''Luigi's Mansion 3'', Luigi, his Polterpup, Mario, Peach, and a few Toad assistants have been invited for a vacation at a luxurious high-rise hotel, the Last Resort. Its proprietor, Hellen Gravely, assists the group in checking into the hotel and escorts each of them to their own rooms. That night, Luigi hears Peach cry out in terror and leaves his room to investigate, only to find the initially warm and inviting presence of the hotel to be an illusion. Hellen Gravely appears to personally introduce Luigi to the returning King Boo, whom she managed to set free once again to vow revenge on Luigi. With the others trapped in portraits, King Boo tells him that he plans to finish his collection with a special Luigi portrait. The cowardly brother narrowly escapes though a laundry chute and finds himself in the hotel's bottom floor. He discovers a new Poltergust, model G-00, and climbs to the lobby to discover that Professor E. Gadd was also captured in a painting. Upon freeing him, the two retreat to the basement and Luigi is introduced to two new tools, the Virtual Boo and Gooigi, that will aid him in his trek up the 17 floors of the Last Resort to save his friends and stop King Boo once again.
