Super Mutant Behemoth

Super Mutant Behemoths are giant Super Mutants living in the ruins of Washington, DC. There are five in total, and they do not respawn after you kill them. On all versions of the game, there is an achievement/trophy entitled "The Bigger They Are..." obtained by destroying all five. These giant creatures are created by the Forced Evolutionary Virus (FEV).

Super Mutant Behemoths can be very difficult to kill, as they are the most resilient enemy in the game. But usually when you encounter them, they are being fought by a certain group such as the Talon Company, Enclave Soldiers, or Raiders. These groups of soldiers will usually pack a punch on the Behemoth, knocking off a good chunk of health for you to finish him off. Take a look at the Strategies section for information about how to kill these giant beasts.

Locations
Video locations of all Super Mutant Behemoths

GNR:
 * The Behemoth right outside the entrance to the GNR Building is the easiest to find and is actually impossible to miss if you attempt Galaxy News Radio (quest). You will have ten Brotherhood of Steel members to back you up, though they are not invincible and most will likely be killed quickly. One of the Brotherhood members is in possession of a Fat Man weapon and will die quickly, before having a chance to use it. The lamppost in the area is fragile-looking, but the Behemoth considers it a wall, and it can serve as effective cover from the Behemoth. If you have trouble defeating this behemoth it’s possible just to run to door of the GNR building. There is a back exit to this building so you will not have to face him on the way out. Also when you quick travel back to this location you will be placed behind the sandbags pretty much out of harms way near the door. Another possible strategy is to take cover under the GNR building, coming out when your AP recharges to use VATS.

If you do not need to do the GNR quest (e.g. you went straight to Rivet City), you may find on arrival at GNR the Super Mutant Behemoth will smash down a wall nearby and "break in" to the square, attacking you.

Also, if you did skip the Following in His Footsteps Quest and have already located your father, you will need to fight all of the Super Mutants alone up until you are in front of GNR. Then a few of the Brotherhood will be fighting the remaining Super Mutants. The Super Mutants will win leaving only two or three left. As soon as you leave the building you are in, the explosion will trigger and the Behemoth will appear. If you retreat to and stay in the building, you can slowly hurt him because he cannot enter this location.

Evergreen Mills: YouTube video for Behemoth at Evergreen Mills:
 * In Evergreen Mills, the Raider-controlled train yard, a behemoth is trapped by an electric fence. When approaching the area from the south, the generator can be easily destroyed with any rifle; a melee will ensue in which most of the raiders will die killing the behemoth. However, no experience will be gained by this method. The easiest method of legitimately defeating the behemoth is to clear the area of raiders, lay several Bottle Cap Mines near the gate(but far enough away from the generator so they don't detonate when it explodes) and then release the locks on the cage. Alternatively, the Behemoth can be attacked by ranged weapons through the mesh gate while the generator is still active. The roof of the nearby train car offers a clear view of him.  However, it is possible that the Behemoth may escape during the player's shootout with the Raiders, forcing the player to deal with him in the tight confines of the camp.  Another alternative is to jump between the carriages to get to the other side of the carriages.  The behemoth will try to get through but can't and eventually will run off.  Just jump back over and it comes back, repeat until the Behemoth dies. Normally the Behemoth won't attack any followers with this method.

Capitol Building: YouTube video for Behemoth at Capitol Building:
 * A Behemoth can be found in the Capitol Building fighting Talon Company mercenaries at the west entrance. There is a considerable amount of fighting between Super Mutants and Talon Company so it's possible to sit back and watch the fun. You can also find a room next to the dome with the Behemoth containing a computer which, when hacked, will allow you to activate the turret system in the dome. There are several turrets that are activated by this command, so it'll likely make things much more interesting.

Takoma Park: YouTube video for Behemoth at Takoma Park:
 * A Behemoth is located southwest of the Takoma Industrial in Takoma Park. There is a truck near a water tower a few feet away. On the truck you can see a dead mercenary and a switch that activates some artillery that makes the fight a lot easier. This artillery will fire several times before breaking (you can fix it with a Science skill of 33).

Jury Street Metro Station: YouTube video for Behemoth at Jury Street Metro Station:
 * One final Behemoth is located at a Super Mutant camp, after following a series of search party notes (Unmarked quest: Searching for Cheryl). The final note takes you to a camp between the Jury Street Metro Station and Evergreen Mills. Both are located due west of Vault 101. You do not need to get these notes to make this Behemoth appear. Keep going west from Vault 101 until you find Jury Street Metro Station. Head further west from there until you find a bunch of wrecked train cars along with a few Super Mutants. If you're having trouble finding it follow the tracks heading NE from Evergreen Mills, or you can just look for the train tracks SW of Jury Street Metro (hint: they come out of a tunnel in the hill). On these tracks are several overturned railway carts. One of them is a large empty storage container, with the open part facing the Jury Street Metro area. In this container are several "Cart Cages" (shopping carts pushed together to make a cage). One of these contains a teddy. Open the cart and grab the teddy. It is not necessary that you take the teddy, because simply standing next to the cage and waiting will cause the behemoth to spawn above the train tunnel. However, taking the teddy might cause the behemoth to spawn because it is angry that somebody stole his precious teddy! When he spawns, the Behemoth may get caught up fighting Talon Company/Regulators (depending on your Karma) near the Jury Street Station.

Note: You can wait up on the edge overlooking the train carts and wait 12 hours and the behemoth will appear, but sometimes Enclave soldiers may appear as well. They will ally with you against the behemoth but once he dies they turn on you. Fawkes can be helpful here as well.

It's also possible to snipe the Behemoth from the cliffs near the entrance to Evergreen Mills. He won't be able to trace the fire back to you and will continue to schuffle around. Blackhawk is a good weapon for this job.

If you want to resurrect the Behemoth from GNR building for another fight, use ID# 1F1F9 (make sure the roof is high).

Appearances
The Behemoth appears only in Fallout 3. A robot also named Behemoth can be found in Fallout Tactics.

Physical Appearance and Equipment
Behemoths are roughly 20 foot tall Super mutants with an extremley large penis, which is approximately 3 times as long as a normal humans body. They have necks so thick with muscle that they merge into their bodies and extremely large build. They have very large mouths, which assists them to suck a big fat penis and they also have no gag reflex which makes them perfect for the job. Some Behemoths carry fire hydrants which can greatly damage the player and swiftly kill any living being in their radius. Their legs are also packed with muscle and provide them with a significant amount of speed and give the ability of "power humps", considering their size. Although, the captured Behemoth at Evergreen Mills, apparently, was stripped of all his belongings. They also wield car doors, which are used as shields. The shopping carts on their back serves the purpose of carrying their victims with them like a food ration. Another point to consider would be the skulls linked together by a chain to form a necklace of victims, yet another intimidating feature to these already terrifying creatures. Behemoths seem to be pack rats or the super mutant equivalent to a mule, for they carry large amounts of equipment which most likely is stored in their shopping carts. Though, in consideration of the "cart cages" often found at Super Mutant camps, they might also be used to carry captured humans. Smaller companions like Jericho or Clover will rush into battle at closer range (no matter what weapon, they will get close), and if the Behemoth wields a fire hydrant, he will knock them down in one hit, leaving them vulnerable to a quick second attack, an effective two-hit kill by the Behemoth.

Strategies

 * I have found a tactic that proves to be most effective. If you masterbate 3 times in 10 minutes right before a fight with a behemoth, you will feel more confident and thus have a greater chacne of winning the battle. (YOu will probably be so happy by your victory that you will want to masterbate again, i know i did).


 * Behemoths are usually supported by normal Super Mutants. Give the guards priority, but keep moving to avoid being hit by the Behemoth.


 * Due to their large size, it is relatively easy to achieve head shots in VATS. If the player has sufficient first-person shooter experience, it is also not too difficult to achieve head shots without VATS, assuming the gun that player is using does not have significant spread.


 * Due to their large size, Behemoths cannot enter hallways or get under low hanging rubble and have difficulty getting around any large obstruction. The player can use terrain to their advantage to keep themselves out of melee range while gradually taking the Behemoth down at a safe distance.


 * An all purpose strategy for any ranged player is the Dart Gun which will cripple the Behemoth's legs with a single shot regardless of the player's Small Guns skill. With the Behemoth's mobility reduced practically any ranged weapon can be used to finish it off. Care should be taken, a crippled Behemoth can still deal massive damage if allowed to get back into melee range.


 * Small Guns are highly ineffective unless aimed at the Behemoth's head. However, a Chinese Assault Rifle in good condition works fairly well, and can bring down a Behemoth with a handful of mags worth of full auto fire. Keep backing away from the Behemoth while emptying your gun into it, don't use VATS (as it makes you stand still for a second or two after firing). Small Guns specialists will find the Victory Rifle is also efficient and capable of knocking a behemoth down.


 * Big Guns specialists with a rank of 100 will find a perfectly repaired Fat Man does 1674 damage per shot and has a potential to knock a Behemoth down. Using one Mini-Nuke and following up with the Minigun while the Behemoth is staggering is a quick and effective strategy. The Missile Launcher is also quite effective at persuading Behemoths to die, and a direct hit to the head with a missile can knock off a decent chunk of its health, even if the launcher is in poor condition.


 * Laying land mines and luring the Behemoth through them is an effective tactic. Bottlecap Mines especially are great because of their high damage.


 * An Unarmed specialist can also fight them barehanded, though dosing on as much chemical assistance as possible is recommended. Behemoths are susceptible to knock-down criticals, though targeting their towering heads outside of V.A.T.S. is much more difficult. Targeting arms for critical strikes can reduce their impact and effectiveness. On hard difficulty, well-timed and frequent stimpack use will be needed to survive the brawl. This is not suggested because the behemoths sheer strength and brute force aggression.


 * If Dogmeat is still traveling with you, order him to stay in a safe place. Dogmeat's only attacks are close range melee and he can be damaged quickly by the Behemoth. This can be dealt with somewhat with the dialogue option to use a Stimpak, which is available even during combat, but keeping Dogmeat out of melee range is safer. This advice actually is also good for any NPC followers you might have, since they will often just stand in place attempting to fight the behemoth.


 * The Terrible Shotgun is particularly effective against the Behemoth as its large size makes getting the entire spread of buckshot on-target relatively easy. If staying that close to the Behemoth is too daunting, bring a companion, preferably one equipped with Power Armor of some kind, to act as bait while the player rapidly unloads a clip into the beast's back. Just be quick, even the most durable companion can't weather that kind of beating for long.


 * But still one of the (or probably the) best ways to kill a Behemoth is the use the wicked power of the Experimental MIRV and kill the Behemoth in one hit. Or technicaly 8 mini Nuke hits.

Actual Size
When initially designed Behemoths may have been smaller, about half the size they are now. The skulls, car doors and fire hydrants they carry are all bigger than any skull, car door or fire hydrant in the wasteland. This is evidence that the Behemoth's size could have been increased after creation. If you spawn a Behemoth they are not the size encountered in-game. Rather, they are only slightly taller than Fawkes.
