The Steward Guide

Luigi's Mansion 3 Guide: How To Defeat ALL 18 Bosses (1)

The Steward uses the suitcases strewn around the boss arena as a shield to protect itself from Luigi's Strobulb. In order to hit the Steward, the player needs to use the Strobulb to cause him to lift the suitcase, then use Luigi's Stomp move to knock it from his hands. This will leave the Steward open to a second Strobulb blast that will stun him and leave him open to a slam attack from the Poltergust. Do this three or four times and he should be defeated.

Chambrea hides a suitcase in her body that Luigi needs to retrieve. In order to harm Chambrea, the player needs to stun her with the Strobulb and follow up with a plunger shot to the suitcase. Luigi can grab the plunger with the suction ability of the Poltergust and slam Chambrea into the ground. Chambrea will eventually flee to a different room. Luigi can use the Dark-Light Device to check the corridors, as she will leave an imprint on the door of the room she is hiding in. Repeat the same process as before to defeat her.

Kruller Guide

This boss fight requires the use of Gooigi to succeed. Send Gooigi into the shuttered area while dodging Kruller's water pistol, as the water will cause Gooigi to melt. Use the Strobulb to cause Kruller to grab his sunglasses and follow up with a Stomp to knock them off his head. Once his glasses are gone, the player can use the Strobulb to stun Kruller and grab him with the Poltergust for a slam attack. Do this three or four times and he should be defeated.

Chef Souffle Guide

Luigi's Mansion 3 Guide: How To Defeat ALL 18 Bosses (4)

Chef Souffle can use his large pan to hide from the Strobulb. Once he lifts the pan, fire a plunger and grab it with the Poltergust to wrench it from his hands, leaving him vulnerable to being stunned by the Stroblulb and slammed with the Poltergust. After he has taken damage, Chef Souffle will start spinning and will chase Luigi around the kitchen. The Chef is invulnerable during this phase, so just keep running from him and use the ovens as cover. He will eventually wear himself out and return to his regular state, where he can be hit with the Strobulb and Poltergust.

Amadeus Wolfgeist Guide

Luigi's Mansion 3 Guide: How To Defeat ALL 18 Bosses (5)

Amadeus Wolfgeist will start the battle by causing the chairs in the auditorium to fly at Luigi. Just keep dodging them until all of the chairs are gone. He will then send out a group of dancing ghosts to hassle Luigi, all of which can be defeated by using the Strobulb and the Stomp to destroy their masks, leaving them open to a second Strobulb and the Poltergust.

Amadeus will then possess the piano and will use his new form to attack Luigi. Keep dodging the piano's diving attacks and use the Stomp to dodge the shockwave whenever it hits the ground hard. The piano will eventually leap on the stage and shoot bombs at Luigi. Use the Poltergust to grab a bomb and fire it into the lid of the piano, which will stun it. Luigi can then grab the piano with the plunger and throw it on the ground, causing Amadeus to appear. Amadeus can then be hit with the Strobulb and a Poltergust slam attack.

There are two more phases to the piano stage of the battle and it will start firing its keys like missiles. Just back off as much as possible in order to have more room to dodge the keys as they spread out. Repeat the bomb and plunger tactic two more times and Amadeus will be defeated.

King MacFrights Guide

Luigi's Mansion 3 Guide: How To Defeat ALL 18 Bosses (6)

King MacFrights will mount a horse and charge around the arena during the battle. When he lifts his lance and it starts to glow, the arrow slits will start to fire arrows into the arena. The arrows will sometimes drop healing hearts when they hit the opposite wall.

Wait for King MacFrights to charge Luigi directly and hit him with a charged-up Strobulb shot, leaving him vulnerable to a plunger shot, which can be grabbed with the Poltergust and used to slam him into the ground. The King's armor will break and he will come at Luigi in his ghost form with his shield. He will eventually grow dizzy from the chase and will be open to a hit from the Strobulb and a Poltergust slam attack.

Dr. Potter Guide

Luigi's Mansion 3 Guide: How To Defeat ALL 18 Bosses (7)

The player needs to grab the Saw item with the Poltergust, which might be tricky to see if you don't know that it's in the arena. Dr. Potter will hide behind his potted plant and will use it to attack Luigi. Just wait for the potted plant to grab onto another flower when it attacks and chop it in half with the Saw. This will leave Dr. Potter vulnerable to being stunned and hit with the Poltergust.

The Kaiju Ghost Guide

Luigi's Mansion 3 Guide: How To Defeat ALL 18 Bosses (8)

Luigi doesn't actually fight the ghost boss of the Paranormal Productions fight. Instead, he has to help him film a movie scene involving a ghost in a monster costume.

The Kaiju Ghost will fire a ball of atomic energy at Luigi, which can be pushed back with the Poltergust in order to deal damage. This will cause the Kaiju Ghost to start burning with blue energy and it will begin firing small balls of fire that need to be dodged. The next time it fires a ball of atomic energy, it will push back against the Poltergust. The only way to harm it during this test of strength is to summon Gooigi and have him use his Poltergust at the same time, which will create enough pressure to fire the ball into the ghost. This process needs to be repeated one more time and will end with a QTE involving both Gooigi and Luigi as they slam the Kaiju Ghost into the ground.

Polterkitty Guide

Luigi's Mansion 3 Guide: How To Defeat ALL 18 Bosses (9)

The Polterkitty is fought several times throughoutLuigi's Mansion 3and will be faced for the first time after defeating the Kaiju Ghost.

T-Rex & Ug Guide

Luigi's Mansion 3 Guide: How To Defeat ALL 18 Bosses (10)

The T-Rex is not as tough as it looks. Wait for the two eggs to drop from the ceiling and grab one of them with the Poltergust. The egg can be fired into the T-Rex's mouth, causing it to chow down and leaving its rib cage vulnerable. Luigi needs to grab the second egg and fire into the T-Rex's chest before it finishes eating. The player will only have access to a single egg during the second phase of the battle. Luckily for Luigi, he has an edible friend in the form of Gooigi. Let the T-Rex chow down on Gooigi and then hit it in the chest with the egg.

The T-Rex will startmoving around during the third phase of the battle. There are piles of rib cages strewn around the room during this phase of the fight, so graba rib cage with the Poltergust, run under the T-Rex, and fire it up into its chest. Ug the caveman ghost will emerge during the final phase of the battle. Just keep dodging his club attacks and wait for him to do a huge swing into the ground, as this will create a shockwave that can be avoided with the Stomp. Run in for a Strobulb hit and a Poltergust slam. Repeat this process four or five times and he should be defeated.

Clem Guide

Luigi's Mansion 3 Guide: How To Defeat ALL 18 Bosses (11)

The fight against Clem is one of the hardest in the game, due to the need to master the sailing controls. Luigi can push or pull the boat with the help of the Poltergust, allowing him to move across the water.

✕ Remove Ads

The pool of the boss arena is lined with spikes, which means that going too close to the edge will cause Luigi to be shot out of the pool. Luckily, the same rules apply to Clem and the easiest way to defeat him is by pushing him into the spikes with the Poltergust, causing him to be knocked out of the arena. Luigi then needs to reach the ladder and climb out of the pool, as you can’t pop your own boat to get to him quicker because the game will force you to inflate a new boat and get back into the pool first. Once you reach Clem, you can hit him with the Strobulb and follow up with a slam attack from the Poltergust. It’s also possible to lure Clem into being hit by one of his depth charges, but this is tricky to pull off in comparison to just pushing him into the spikes.

Serpci Guide

Luigi's Mansion 3 Guide: How To Defeat ALL 18 Bosses (12)

Serpci will create a huge head made out of sand and hide inside of it. Luigi can use the Poltergust to suck up the sand and cause the head to fall about. A crown of snakes will emerge from the sand head and attack Luigi while he tries to suck up the sand. If the snakes hit the ground, they will be left stunned and can be destroyed with a Stomp, which will leave healing hearts behind.

Once the head is destroyed, Serpci will appear and surround herself with snake statues that fire blasts at Luigi. Wait until the snakes use their attack and use the Stomp, as this will make Luigi invulnerable to their attack. Serpci will then be vulnerable to being hit by the Strobulb and the Poltergust.

✕ Remove Ads

In the second phase of the battle, Serpci will summon huge hands made of sand that will attack Luigi. The fists can be broken with a Stomp if used when they are close enough. If the hands hit the ground and create a shockwave, use the Stomp to avoid the blast. Repeat the whole process three times and Serpci should be defeated.

Nikki, Lindsey, & Ginny Guide

Luigi's Mansion 3 Guide: How To Defeat ALL 18 Bosses (13)

These three magicians will hide in their top hats throughout the battle. They will fire playing cards at Luigi which can either be dodged or broken with a Stomp. Wait until the hats close in on Luigi for a melee attack and use the Stomp to knock them into the ground. Once the hats are knocked down, you can grab one of their tassels and smash it with the Poltergust, revealing a ghost that can be hit with the Strobulb and slammed with the Poltergust.

✕ Remove Ads

The battle will start again, except that the missing ghost will be replaced with a bomb. The player will need to keep track of which hats have a ghost in and repeat the same process as before. Once the second ghost is defeated, there will be two hats with bombs in them. Just keep track of which hat has the ghost and go for it when they it's knocked to the ground.

Captain Fishhook Guide

Luigi's Mansion 3 Guide: How To Defeat ALL 18 Bosses (14)

This battle will be very familiar to those who playedThe Legend of Zelda: Link's AwakeningandDonkey Kong Country 3,as it's a mixture of the Facade battle from the former (which is one of the best boss battles inThe Legend of Zeldaseries) and Belcha from the latter.

✕ Remove Ads

Captain Fishhook is a ghostly shark with the power to possess the pirate ship that Luigi is standing on. The ghosts around the stage will drop exploding barrels, which Luigi can grab with the Poltergust and toss into Fishhook's mouth. This will cause him to return to his shark form. Just keep dodging his attacks and wait for him to get his hook stuck in the ground, as this will leave him vulnerable to the Strobulb and a Poltergust slam attack. The second phase is a repeat of the first.

In the third phase of the battle, Fishhook with try to tip the ship over. Run over to the sign with the target painted on it, fire a plunger at it, and grab the plunger with the Poltergust. Luigi can use this to hang from the ship when it gets tipped in the air. Fishhook will then possess the side of the ship, but the process of defeating it with the barrels is the same. The target sign will move in later phases of the battle, so aim the plunger carefully.

✕ Remove Ads

Fishhook will be able to swim through the ship itself during the final phase of the battle. Just run away from him and repeat the previous process to defeat him.

Johnny Deepend Guide

Luigi's Mansion 3 Guide: How To Defeat ALL 18 Bosses (15)

This battle requires the help of Gooigi to complete, but he needs to be careful, as Johnny Deepend can spit out a jet of water that can melt Gooigi where he stands.

Summon Gooigi and have him hide behind the pillar next to the valve at the far end of the room. Switch to Luigi and grab a ball with the Poltergust. Wait for Deepend to start building up for a water attack and fire the ball at him,leaving him stunned. Switch back to Gooigi and use the Poltergust to activate the valve, causing the water in the swimming pool to drain and trapping Deepend in the plug socket.

✕ Remove Ads

Climb down the ladder into the pool and grab a ball with the Poltergust. Fire the ball at Deepend to stun him, pull off his sunglasses with the Poltergust, hit him with the Strobulb, and follow up with a slam attack from the Poltergust.

The Dancers & DJ Phantasmagloria Guide

Luigi's Mansion 3 Guide: How To Defeat ALL 18 Bosses (16)

The first phase of this battle involves Luigi battling ghosts in a haunted disco. Luigi has to face off against a group of hooded ghosts on the dancefloor, one of whom has the elevator button that he needs to continue. The ghost holding the key can be revealed with the Strobulb (just look for the flash) and then hit it with a Stomp. The intention is to try and capture the ghost holding the key each time, which will prompt the DJ to enter the battlefield.

✕ Remove Ads

DJ Phantasmagloria will perform a spin attack with two flaming vinyl records in her hands. She can be knocked back three times with a Stomp attack and when she reappears, hit her with the Strobulb to cause her to hide within her afro. Once she starts hiding, the afro can be knocked off with a Stomp, leaving her vulnerable to the Strobulb and a slam attack from the Poltergust. DJ Phantasmagloria will start rolling flaming vinyl records across the stage in later phases of the battle, but the same process can be repeated to defeat her.

Hellen Gravely Guide

Luigi's Mansion 3 Guide: How To Defeat ALL 18 Bosses (17)

✕ Remove Ads

The battlefield has a column in its center that can fire red lasers and create damaging walls of energy. If a single red laser appears at the bottom of the column, use the Stomp to avoid it. If multiple lasers appear, then run in the opposite direction until it stops. There are lights around the top of the arena that can be hit with the Strobulb to cause healing hearts to drop to the ground.

Gooigi is needed to win this battle. Summon Gooigi and send him through the grates into the underground area below the arena. There are four switches that can be pulled to turn off the colored walls of energy. The Poltergust can be used to push or pull the barriers that look like turnstiles. Keep an eye on Luigi and be ready to switch back if it looks like the walls or Hellen Gravelley is about to hurt him.

Wait for Hellen to hit the ground with her mirror, as this will leave her vulnerable to the Strobulb and the Poltergust. The reason why its best to shut off the walls before attacking her is that Hellen will drag Luigi around the arena and possibly pull him into an energy wall. It's possible (but risky) to land an attack on Hellen without taking out every wall.

✕ Remove Ads

The later phases of the battle are similar to the first, except that the laser column will switch between its ground beam and multiple beams. If flashing blue lights appear in the underground, then that means the area will be flooded and Gooigi will need to move. Keep repeating the process and Hellen will be defeated.

King Boo Guide

Luigi's Mansion 3 Guide: How To Defeat ALL 18 Bosses (18)

King Boo is back for an epic showdown on top of the Last Resort Hotel. If there are any Golden Bones left in E. Gadd's shop then buy them now, as this is the last challenge of the game. King Boo uses several attacks during the battle, including striking the stage with his tongue (dodge this), whipping across the stage with his tongue (use the Stomp to avoid), lighting up the floor with electricity (run to the uncolored area of the floor), and spitting out fireballs which need to be avoided.

✕ Remove Ads

The most important attack that King Boo uses is when he throws a huge spiked ball at the ground, as bombs will come out and land on the stage. Grab a bomb with the Poltegust and fire it into King Boo's mouth, knocking him down to the stage. Use the Poltegust to grab King Boo's tongue and get Gooigi to do the same for a double slam attack.

King Boo will summon a clone for his second phase. It's easy to tell which is which, as the clone's eyes will go dark throughout the battle, while King Boo's will always stay bright purple. Repeat the same process as before and make sure to fire the bomb at the real King Boo. The third and final phase will involve King Boo splitting himself into three. Use the same tactic as before to identify the correct one. The attacks will become more intense, so just keep dodging and wait for the right time to strike before finishing King Boo off for good.
