- Hellen Gravely

Hellen Gravely is the owner of The Last Resort and one of the main antagonists in Luigi's Mansion 3. Her name is likely a reference to "" and "graves." She owns a ghost cat named Polterkitty, and has a tendency to assume a haglike, disheveled form when upset, which she is greatly embarrassed about and suppresses using makeup.

Appearance
Hellen Gravely is a tall, slender woman with purple skin, blue hair in a beehive style, and yellow eyes. Being a ghost, she is transparent and glows. She has the face of an elderly woman, with visible creases near her lips and thin, dark blue eyebrows, though she does wear makeup, notably red lipstick, purple eyeshadow, and black eyelashes, as well as a good deal of jewelry, namely her necklace with a silver, hexagonal charm, and a similarly shaped purple glowing jewel embedded in it. She also wears two circular earrings that are also silver with jewels in them, as well as a pearl bracelet on her left wrist. She has a white dress with no sleeves or upper back that tapers near the bottom, before flaying out into a circle shape as it rests on the ground. It has a window on the chest shaped like the jewel in King Boo's crown, as well as a diagonal dark blue stripe below the waist, beneath which the dress becomes a lighter blue.

In the beginning of the game, she, like Steward, Chambrea, and the Goobs, does not glow, and has opaque skin, however instead of wearing a mask like the others, she instead wears black-framed shades with gold reflective lenses. When confronting Luigi to introduce him to King Boo in the 5th Floor (RIP suites), she additionally wears an open magenta cape covering her back, with a large collar, which ties together just above the gem on her necklace.

In the prelude to her boss battle in the Master Suite (15th Floor), she reveals that her makeup, referred to as GheistPaint brand in the Guide, is actually a powder that masks her true appearance, which shows as she gets enraged before her battle. Her true form is much more bony, as she has very defined cheekbones, a larger, sharper chin that sticks forward more, a furrowed brow that has a more defined "socket" as her eyes are set in more, showing shadows underneath them, as well as having a larger, crooked nose. Her eyes turn red, and her hair gets messy, with the once solid, flowing shapes being replaced by smaller bangs the flay out in random directions, and have blocky spirals at the end instead of being straightened. Her dress is also messier, with more visible wrinkles, and the bottom of the dress being torn into somewhat neat triangles, showing some of her ghostly tail underneath.

History
Tricking Professor E. Gadd into coming to her hotel, Gravely released E. Gadd's collection of ghosts (including King Boo, whom she is infatuated with), leaving the professor to be captured inside a painting. She later invites Luigi, Mario, Princess Peach, and three Toads to her resort, with the intention of having them captured as well - while skeptical of the plan, King Boo made preparations regardless. When meeting Luigi’s vacation party, Hellen wears sunglasses and hides her semi-transparent aura in order to disguise her true nature as a ghost, similar to the other ghosts wearing masks to disguise themselves. She welcomes the group to her hotel and escorts them to their rooms on the fifth floor, planning to ambush them in the night so King Boo could trap them in portraits.

After Hellen successfully captures Mario, Peach, and the Toads, she returns to the fifth floor shortly to Luigi reintroduce him to King Boo. She watches with admiration as King Boo tries to imprison Luigi in a painting, only for him to narrowly escape down a laundry chute leading to the basement, where he finds the Poltergust G-00. Throughout Luigi's adventure, Hellen watches his progress from the Main Observation Room on the fifteenth floor, growing increasingly frustrated with her staff's inability to capture Luigi. By the time Luigi defeats Captain Fishook in The Spectral Catch and rescues the third Toad, Hellen finds herself confronted by a disappointed King Boo; despite her efforts to placate him, she is quickly brushed off as King Boo takes one of the two remaining portraits to the hotel's roof without saying a word.

When Luigi reaches the Master Suite, Hellen confronts him over a large monitor, revealing that she has Mario's painting in her private office. While clearly upset with Luigi's progress, she comments that his presence here gives her the chance to personally defeat him and present him to King Boo, hopefully restoring his trust in her capabilities, and losing her beloved cat, Polterkitty. She then continued monitoring Luigi from her office, leaving him to contend with her remaining ghost minions and her high-tech security measures as he sought the keys to open the path to her.

When Luigi finally reaches her, she angrily blames him for her losing everything, unintentionally exposing her true face in the process. After reapplying her makeup, she turns her office into an arena and battles Luigi personally. She is ultimately defeated and captured in the Poltergust G-00, sharing a capsule with Polterkitty. She is last seen during the credits, admiring a captured and frustrated King Boo from her own capsule.

Battle
Hellen Gravely fights primarily with a laser-emitting pillar in the center of her arena. Initially, she retreats from the room and appears on the monitors along the back wall, laughing at Luigi while the pillar sweeps the room with red laser beams. Depending on whether there is one laser or three, Luigi may or may not be able to Burst over them; in the latter case, he should stay close to the pillar in order to cover ground more efficiently. Later in the battle, the pillar may release three lasers on both sides of itself.

After the laser attacks, Hellen will cause the pillar to project four colored energy barriers (green, orange, purple, and yellow) in a cross formation before it begins slowly rotating. Using the pipes and grates at the edges of the room, Luigi can send Gooigi into a lower floor to deactivate the barriers by pressing the color-coded switches. Hellen herself will float around the room, occasionally reversing the direction of the barriers' rotation; when enough barriers are deactivated or Luigi gets too close to her, she will attempt to hit Luigi with her mirror. If she fails, it will become stuck in the ground, leaving her vulnerable to the Strobulb. After stunning her, Luigi can then vacuum her, though if any of the barriers are still active, running into one will cause her to break free. If Luigi takes too long to deal a significant amount of damage to her, she will go back behind the monitors and do another laser cycle, reactivating the barriers afterward.

After taking enough damage, Hellen retreats to the background, reapplying her makeup before resuming her attack pattern at a greater intensity. The red lasers move faster and more erratically, with three and even six-laser configurations becoming more common. When the colored barriers activate, Hellen will occasionally attempt to hinder Gooigi's sabotage efforts by flooding parts of the lower level with water; this is telegraphed by blue squares flashing over the affected areas and tap graphics appearing on some of the monitors. She also becomes more aggressive against Luigi, attacking when one or two barriers are deactivated; in her final phase, she'll start attacking the moment she returns to the arena.

When her HP is fully depleted, Hellen will struggle against the Poltergust's suction before abruptly stopping and signalling Luigi to wait a moment. She then applies her makeup one last time before being sucked into the vacuum. Luigi can then use the Dark-Light Device on Mario's portrait to free his brother and access the Rooftop where King Boo is.
