Bogmire

Bogmire, the Cemetery Shadow (Japanese: シャドーマ Shadōma), is a purple portrait ghost of unknown age from the game and the boss of Area 2. The ghoul resided in the Graveyard of Luigi's Mansion during the events of the game. Bogmire is the manifestation of the mansion's fear and despair, although the powerful ghost itself does not know who to fear or what to despair. Bogmire can summon shadowy duplicates of himself. He can also teleport around an area with a flash of lightning. Bogmire was the boss of the second area of Luigi's Mansion.

Story
Luigi encountered the powerful Bogmire during his quest to save his brother Mario from King Boo. During Luigi's investigation of the Graveyard, the green-clad hero discovered three Skeleton Ghosts hiding in the tombstones. After dispatching them with the Poltergust 3000, the main headstone began to glow. As Luigi approached the stone, Bogmire revealed himself and transported Luigi to his cemetery lair.

Once in the lair, Luigi and Bogmire began to battle. To attack the novice ghost hunter, Bogmire created shadowy clones of himself, ranging from miniature-sized ghosts to enormous duplicates. These shadowy spirits would then attack Luigi as Bogmire warped around the arena, avoiding the green-clad hero. Unfortunately, Luigi discovered he could not suck Bogmire up with the Poltergust 3000. To capture Bogmire, Luigi had to pull in one of Bogmire's shadow clones with the Poltergust. The ghost would then form into a shadowy ball at the end of Luigi's vacuum weapon. The plumber could then fire the shadow ball at Bogmire, surrounding the ghost in darkness and rendering him vulnerable. With the ghost's heart revealed, Luigi could finally use the Poltergust against Bogmire. However, as Luigi was pulling the powerful ghost in, the plumber also had to avoid the shadowy duplicates who converged on his position, hoping to free Bogmire and injure Luigi. Should the novice ghost-hunter fail to catch Bogmire in one go, lightning strikes will occur, and where the lightning strikes a Bogmire Shadow will appear, creating a ready-made army for the next phase in the fight. Eventually, after an easy battle, Luigi emerged the victor and captured Bogmire. Returning to the Graveyard, Luigi discovered the chest to the key to the Courtyard and the next leg of his journey began.

Trivia

 * Bogmire's name derives from bog and quagmire (or just mire), two types of swamps.
 * The Spoils Bag from The Legend of Zelda: The Wind Waker has a face that much resembles Bogmire's.
 * Bogmire's Gold Frame pictures a Bogmire Shadow, while the Bronze and Silver frames portray Bogmire as he actually appears in the game.
 * Curiously, Bogmire is the only boss ghost who doesn't attack Luigi personally (although this can be argued with King Boo), preferring to send clones of himself to attack Luigi instead. Also, he is the only portrait ghost who doesn't have any lines whatsoever during the whole game. It is impossible even to scan his heart for a line.
 * He possibly shows the least emotion out of any ghost in the entire game (although like all other ghosts, he will struggle to get away when Luigi tries to vacuum him).
