20 Hidden Bosses Only Experts Found (And Where To Find Them)

In Fallout 4, there are myriads of hidden bosses and mini-bosses that players can seek out and find for themselves. Some of these bosses are harder than others, but the most challenging part for most of them will just be finding them. Of course, if you stumble across a mini-boss unaware, that can also cause some frustration if you are not prepared for what you accidentally found. Navigating both of these challenges is what makes the Fallout games as iconic as they are.

There are many bosses and quests players can miss in Fallout 4, all of which are scattered throughout the open world. The franchise has a long history of hiding special quests and bosses around every corner, making players work to find them. To cut down on that finding time, this guide has some of the best bosses you might never have seen as you traversed across the wastelands.

20 Grun

Super Mutant Leader

Fallout 4 sometimes gets mixed reviews by fans, but its Nuka-World DLC, based around super-mutant gangs and the series’ famous Nuka-Cola, has been a hit. With so many super mutants running the show, quite a few of them become iconic bosses. One of the most hidden ones is Grun, the old gang leader at Vim! Pop Factory that was so crazy, he was locked in the basement.

A player can go the whole DLC without being bothered by Grun and they never have to let him out, but if they do, it’ll be a huge battle. If the Sole Survivor fights him, he’s a super-mutant behemoth who packs a punch. If they run, the gang members of the factory will fire on him instead. After all, he’s crazy enough to battle his own people and this is your best shot at beating him easily.

19 Monster Of Carhenge

Hidden Guardian

Bethesda loves making games full of easter eggs for fans to find and enjoy. One of the most well-known and fan-loved easter eggs in Fallout 4 is Carhenge, a circle of decrepit cars that look like the famous Stonehenge. However, what is even more interesting, and surprising, is the structure’s guardian. The monster of Carhenge has spooked more than a few fans and has defeated even more.

Once a player finds Carhenge, they will also be met with a large, dangerous super-mutant behemoth ready to gobble them up. While the monster of Carhenge doesn’t have an official name, his location, his arrival, and his massive presence make him a sight to behold. He and Carhenge can be found directly south of Walden Pond, ready to greet any wanderers that find them. You can see how this fight plays out in YouTuber DefectiveGaming‘s video, but you will want to be well-prepared with a good weapon and an overpowered perk from Fallout 4 to face this one.

18 Red Death Mirelurk

A Docile Surprise

Fallout 4‘s Far Harbor is known for its creepy monsters. After all, most of the enemies are beasts crawling out from thick, opaque fog. The most unsightly creature, however, is easily the island’s special, sinister Mirelurk. A Mirelurk with fierce, piercing, glowing red eyes named the Red Death.

You can find
The Great Hunt
mission by going to Far Harbor and talking to the Mariner. At the end of the quest,
players will have to decide whether to reveal the true nature of the enemy
to the people of Far Harbor or not. Players do not need anything special to beat this one.

Red Death can be found, aptly, on Red Death Island. It’s known to be a monster of legend, however, under more investigation, it’s discovered to be a small, docile bloodrage Mirelurk that’s just been sinking ships with its disarming red eyes. This little monster is only found in The Great Hunt mission, so fans may not find him. His tale of infamy turned hilarity is a great one, though, and is very much worth debunking.

17 Red Tourette

Desperate Raider

Red Tourette and her band of bandits are residents of the Federal Ration Stockpile, an area that quite a few side quest missions lead to. However, these missions don’t require interaction with Red Tourette at all. They all mostly involve finding different items stored or lost around the complex. If a player wants to fight Red Tourette head-on, her logs will paint a far more depressing picture.

Unlike many bloodthirsty raiders, Red is merely desperate to find her sister, Lily, who she thinks is being locked up somewhere. It’s pretty clear to fans that Lily has likely passed on. As far as random location bosses go, Red Tourette’s sad backstory is what sets her apart. To get to her, check out YouTuber Rhapsody‘s video, which takes you through the facility she’s hiding in. If you choose to fight her, she is a tough boss that you will likely want to snipe from a distance.

16 Mythic Deathclaw

Random Encounter

Deathclaws have been the most iconic monsters from the Fallout series for a long time. While ghouls and supermutants are more plentiful and have more complex backstories, Deathclaws are the boogeyman that go bump in the night.

In Fallout 4, one of the strongest Deathclaws is the Mythic Deathclaw, a very rare version of the species that give any wanderer a challenge. Make sure you have one of the best unique weapons like Final Judgement to face this boss.

The Mythic Deathclaw is immune to the Wasteland Whisperer perk.

This version doesn’t spawn until the player hits level 91, but infamous Bethesda bugs can see it spawning as early as level 35 in front of the Starlight Diner. Otherwise, they randomly spawn, so a player just has to leave it up to chance and hope these bloodthirsty beasts only catch them on a good day. For closer fights, a Gatling Laser weapon will work fine, but you can also defeat them from further away with a high-powered sniper rifle.

15 The Ghoulrilla King

Power Of The Pack

While the Nuka-World DLC centers around a mad super-mutant gang, there are many more interesting places in the area. For example, in the amusement park, there is an area called Safari Adventure that is the home of ghoulified gorillas and their human companion, Cito. Cito can become a quest-giver for the player, sending them away on various missions.

While it is a possible box, keep in mind that there are ways to
keep the gorillas docile who will then team up with the player
. You will have to complete The Nuclear Option and give the evacuation order to do so, but you then have a gorilla companion who will defend your settlement.

However, cross Cito the wrong way, and the Sole Survivor can be targeted by him and his gorillas. The most powerful of these “Ghoulrillas” is their leader, a ghoulrilla king that Cito calls Chris. Like all radioactive, wasteland creatures, Ghoulrillas pack a punch and, in the case of Chris, come in a pack. Doing missions for Cito might just be a safer idea. The ghoulrilla king will only spawn if the Safari Adventure quest has not been completed when the player reaches level 50.

14 Dead Eye

Blind Danger

Fraternal Post 115 is a location that has quite a few faction missions nearby. Regardless of the missions, though, the place is unique because its leader isn’t the average super mutant: he’s blind. Dead Eye, perhaps a little too aptly named, runs the enemies there. He’s even more unique because the player might never directly encounter him. After all, if Dead Eye detects the Sole Survivor, he alerts others and several super mutants to come running for a fight.

If the player does fight Dead Eye, though, the two can have a fascinating battle of melee weapons. Fraternal Post 115 is a part of Cambridge and particularly an Institute, Minutemen, or Railroad, can send the Sole Survivor there. The tricky part about this fight is the swarm mechanic, so if you can kill Dead Eye fast enough to avoid the alarm, you will be better off. However, this will take some forethought and overpowered weapons.

13 The Director

Master Of Robots

The Director and his community of robots live in the General Atomics Galleria and are a unique band of characters. There are no humans living there at all, and were simply meant as an example of how things would be run by robots, but the war has left them to their devices. However, despite how fascinating they are, from a little investigation, the player quickly discovers that the reason there are no humans is that The Director himself eliminated the previous human supervisor. That’s how a robot became the leader of other robots.

It’s possible to get out of the place without a scratch, but if The Director becomes displeased, a player can suddenly become an easy target. Moreover, if the Sole Survivor cares a lot about justice, they can take ending a robot criminal into their own hands. If you do go that route, shooting The Director should not prove difficult and you can snipe the rest of the hostile robots from The Director’s tower as shown in YouTuber Twothless‘ video.

12 Dusky Yao Guai

Half-Bald Bear

While the Fallout series keeps a set of core species to populate its wastelands, each game has specialized creatures for its area and even new types of old classics to keep them fresh. One example of this is the Dusky Yao Guai, a new and more dangerous version of the half-bald bear.

Like mythic Deathclaws or super-mutant behemoths, Dusky Yao Guai are one of the rarest and most powerful creatures. For casual adventurers, that’s great, but for tougher battle-seekers, that turns into a challenge. One fairly consistent dusky beast can be found on an island north of Rayburn Park near an upside-down red boat. Try using an upgraded Fixer to stealth-hit the Dusky Yao Guai if you are experiencing difficulties.

11 Pink Ghouls

Student Monsters

Throughout the Fallout series, the game has made several locations that paint a more scary or depressing picture than the ruins leave. For example, there are vaults with only one person, vaults that experimented on people that made super mutants, and then there are places like the Suffolk County Charter School. Before the bombs dropped, the government used a small school to experiment with pink goo as a substitute for food. Once the bombs fell, all the children that ate the goo turned into bubblegum pink feral ghouls.

The school is riddled with them, along with notes that tell a player more about their unfortunate ordeal. The most fearsome one is a glowing ghoul found in the lower levels. These pink ghouls pack quite a punch, physically and emotionally. Luckily, they are around level 20 and the main thing to look out for is that they deal radiation damage equal to their physical damage.

10 Big Mack

Powerful Super Mutant

Either through an Institute mission or a random mission involving a toy horse, the player might end up at the Wilson Atomatoys Factory, southwest of Quincy Ruins. The super mutants here are lead by the fierce Big Mack, a large mutant with an even larger minigun. Though the band of super mutants here isn’t large, the group of them are all in between levels 50 and 60.

For any lower-level player, that could quickly become very dangerous. However, defeating Big Mack means the player gets a fan-favorite weapon: the minigun. Though not always practical, they’ve been a staple weapon of many Fallout games. Be aware that his level does scale, but try fighting him from a distance to take him out, as shown in YouTuber Twothless‘ video.

9 Alien

Injured & Hiding

From rockets to mysterious rocks, the Fallout series has had several forays into alien experiences, however, Fallout 4 has one of the most explicit. After a player reaches level 20, an alien spaceship will crash land on the map. This UFO crash site can be found southeast of Oberland Station. Once there, the Sole Survivor in Fallout 4 will find a destroyed flying saucer and alien blood leading into a cave.

Inside, an alien will be found. Donned in a red and white jumpsuit and a green head, he looks like a perfect 50’s alien. He will immediately become hostile and attack, leaving an alien blaster pistol as loot. Fortunately, because of the alien’s injured status, players should not have any issues with this fight.

8 Shipbreaker

4000 Health Enemy

Fallout 4‘s DLCs add a lot of battle content for the big game hunters in the fandom. One of the biggest and baddest monsters is Shipbreaker: the object of an optional quest named after the creature in the Far Harbor DLC. In this add-on, the player helps a downtrodden town against the dangers hiding in the mist. One of these dangers is this optional boss: a fog crawler with over 4000 health and a shiny yellow exterior. Hulking and merciless, this foe can strike panic into the heart of any Sole Survivor.

Use the radio
to find Shipbreaker’s frequency and start the quest.

Shipbreaker’s location will depend entirely on where the player picks up his signal on The Island (Far Harbor‘s setting). Try using a long-distance approach from a good vantage point, as Shipbreaker can do a lot of damage up close. After defeating him, a hermit of an old hunter, Old Longfellow, will award the player Fallout‘s version of a harpoon gun.

7 Passive Deathclaw

One of the strangest, yet most fascinating experiences a Sole Survivor can have is in the Old Gullet Sinkhole, a sinking cavern in Malden. During the great war, the spot was struck and created a deep sinkhole that creatures now hide themselves in. If a player enters, they are bound to meet quite a few unfriendly faces. The most fascinating face, though, is a Passive Deathclaw.

Unlike many Deathclaws that are fiercely aggressive creatures, this Deathclaw will leave a player alone until it detects them as a threat. If played well, the Deathclaw may actually clear out more enemies from the cavern than the Sole Survivor does. Though the creature doesn’t always stay passive, and might attack the player if threatened, it is unique to find a Deathclaw that doesn’t bite down on sight.

6 Hammer

Super Mutant Leader

In Fallout 4, super mutants get to take center stage in leadership. One such leader is Hammer, leader of the super mutants at West Everett Estates. The West Everett Estates were once the nuclear bunker and hideout of Wayne Tournquist and his two sons, but they were driven out by raiders. Then, those raiders were utterly destroyed by Hammer and his gang. Hammer even accidentally eliminated one of the raiders while he was learning the systems from him.

Hammer and his people are only involved in one mission: Quartermastery, a mission given by the Brotherhood of Steel. If a player isn’t in that faction, they may never meet this beast. Hammer drops a missile launcher after he’s defeated, a worthy item for making a big impact. Once more, YouTuber Twothless has a great video showing you how to take Hammer down.

5 Liberty Prime

Well-Armed Robot

For Brotherhood of Steel fans, the return of Liberty Prime is particularly exciting. The winning card against The Enclave, Liberty Prime was last seen in Fallout 3 mowing down enemies. In Fallout 4, depending on the Sole Survivor’s decisions, he could become the enemy.

The paladins are planning on building and using Prime to defeat The Institute, a legion of synthetic humans. The player can side with The Institute, one of the major factions in Fallout 4, making The Brotherhood of Steel their new foes. Smart players will find ways to disarm Liberty Prime and undermine the Brotherhood, but gutsy ones will fight the giant robot head on. If the Sole Survivor attacks the paladins and The Citadel, the huge robot could put his laser sights in their direction for one epic battle.

4 Mirelurk Queen

Fallout fans love their epic battles, and one of the most infamous places in Fallout 4 to seek big monsters is the Massachusetts State House. This historic building greatly changed with time. Instead of a place of politics and diplomacy, the house now holds a waterlogged, beast-ridden Mirelurk den. And most fearsome of all is the heart of that den, an aggressive and merciless Mirelurk Queen.

Along with power armor, get the
Flamethrower and the Missile Launcher
, which allow you to stay far away from the Mirelurk Queen. If she hits you when you are at a low level, you will likely die.

Mirelurk queens are new to Fallout, and have swiftly become the most rare of their species. Oftentimes, power armor is necessary to survive the creature’s heavy blows, and you will need brute force to defeat it. Though she announces her presence with a loud roar, that doesn’t make fighting her off any easier. These tough-shelled queens can be found in several other places, like The Castle and Spectacle Island, but the Massachusetts State House is the most action-packed and dangerous.

3 Lynn Woods Battle

Epic Battle With Multiple Factions

The Lynn Woods are already an interesting place in Fallout 4, between the vicious raiders and a nest of Deathclaws nearby. But nothing is quite as impressive as the resolute tower that can be found within the spindly trees. Made of brick and topped with an ominous siren, the structure looms over the enemies below. You will likely find this area as part of The Devil’s Due quest that takes place in a ravine nearby.

The hidden danger of the tower, though, is that if a player gets to the top and starts the siren, Raiders and Deathclaws will begin a battle below. It’s not a single boss, but instead, an all-out brawl. Daring heroes can join in the fray and have a unique experience in the depths of a haunted wood, however, if someone finds the tower and isn’t prepared for war, they can hide at the top and wait for the fighting to chill out.

2 Captain Zao

A Ghoul Captain

Captain Zao is a ghoulified submarine captain found in the mission Here There Be Monsters. He personally thinks the liberation of Anchorage was a joke, but bears no ill will towards the Sole Survivor. Together, they can even rebuild his submarine. He can be found within the vessel, the Yangtze, south of the Boston Airport. However, if the player calls him a “commie,” Zao will defend his country and traditions and will attack. Notably, if he attacks at this time you will fail the quest.

Speak to Donny Kowalski, on the
docks behind Shamrock Taphouse
, if you want to start this mission and find Captain Zao.

Alternatively, if you choose to help him, you can eventually persuade him to give you his sword after passing three charisma checks. You can see the whole quest walkthrough with the best ending reached by looking at YouTuber BCNS Games‘ video. However, if you want to fight Captain Zao, make sure you are over level 6 and be ready to fight as soon as the dialogue ends.

1 Swan

Not Actually A Swan

One of the most infamous hidden bosses of Fallout 4 is Swan: a super-mutant behemoth hiding at the bottom of a pond. While walking past his pond is initially cute, watching a plastic swan float in the center, it’s actually something the big guy has strapped to his back. Get too close and he will attack. Swan will patrol around the edge of the pond early in the morning, from about 1:00 a.m. to 5:30 a.m., so he might spot you sooner if you approach at this time.

While most bosses have small details to make them look unique, Swan has a look of his own. Between the swan on his back, the canoe tied to his arm, or the behemoth hammer he wields, he’s an impressive foe. Swan can be found in his pond west of Boston Common. Bring enough firepower to survive a toe-to-toe battle with this huge, hulking ugly duckling in Fallout 4.
