Morty

"The tragedy. Oooooh ho ho ho! Is this my end? Is this what I, Morty, director of the finest films, am destined for? How could I lose it... I am a puny, worthless movie director... That's all... Even the sparkle from this beautiful button is now nothing but a dull hue... AHHHHH! My bright red megaphone! Where art thou?! I would give anything to be able to hold my dear, sweet megaphone again..."

- Morty

Morty is a movie director ghost and the eighth boss encountered in Luigi's Mansion 3. Unlike the other bosses, Morty does not need to be captured due to being the only friendly one, and is never directly fought prior to obtaining the elevator button from him. He instead has Luigi fight against various elements as part of a filming project.

Appearance
Morty is a blue ghost with yellow eyes and mouth, navy blue hair and eyebrows, and a slightly French accent. He wears a dark blue sweater and beret, and likes to carry around a large, red megaphone.

Luigi finds Morty fuming over a lost director speaker and attempts to hand it back to him. Morty is then overjoyed, although after noticing Luigi, he then notices that several of his features make him eligible to stardom before starting filming and demanding for a stage crew.

Morty is not fought, but rather filming the battle and gratefully commenting his two "actors" while filming. After Luigi beats the Godzilla-like ghost, Morty will give him the elevator button as a sign of gratitude before flying into his editing room.

Morty can then be seen editing in his office and, if left alone for a short period of time, will then relax after finishing his movie.

Battle
As noted above, Morty is never directly fought. Instead, the player has to fight a Goob inside a monster costume as part of Morty's new movie. The Goob attacks with fireballs from its mouth, either a barrage of small orange ones or a single large blue one. If it's too close to a building or Luigi, it can also swing its claws at them. The player has to bait the Goob into launching its large blue energy blast and then blow it back with the Poltergust G-00 until it explodes in the monster's face. After the first hit, the Goob monster uses orange fireballs more frequently and replaces the blue energy blast with a green one; while Luigi can initially blow it back, the Goob will retaliate with a stronger breath that requires Gooigi's help to overcome. For the final hit, the Goob retaliates to the redirected energy blast by blowing even harder than before; the player must mash the A button to force the ball into the foe one last time.

The third hit destroys the monster costume, leaving only a standard Goob for the player to defeat. Afterwards, Morty expresses gratitude to Luigi, collecting his film reels and leaving for the cutting room, although not before willingly giving Luigi the ninth floor button. However, when Luigi goes to put the elevator button back in, Polterkitty will swipe it, forcing a chase to get it back.

Luigi can go to Morty's editing room and capture him at any time, however capturing him while he is still editing will result in his movie becoming unable to view. If Luigi returns after retrieving the 9F button from Polterkitty, Morty's editing will be finished. When he is being sucked in, he will make a sad pose and do his picture pose with his hands. Unlike when capturing other boss ghosts, Luigi expresses guilt about his actions (even more so if he is not allowed to finish his film), likely because Morty was friendly and willing to give Luigi the button he was holding.
