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. There is an achievement/trophy in Fallout 3 entitled "The Bigger They Are..." obtained by destroying all five. These giant creatures are created by the Vault 87 strain of Forced Evolutionary Virus (FEV).

Characteristics
Behemoths are enormous super mutants, standing approximately three to four times as tall as a normal human. Some behemoths carry makeshift clubs made from fire hydrants, and often dress in armor made from scrap metal, including a car door acting as a makeshift shield, and carry severed human heads around their necks and waists. They also have shopping carts on their backs as sort of backpacks, for carrying their victims with them like food rations.

Vault 87 super mutants become bigger and stronger the older they become after being exposed to FEV. Super mutant behemoths are the biggest super mutants in the Capital Wasteland which means they are also the oldest. Each behemoth in Fallout 3 looks unique: some do not wear armor, some do not have weapons, etc. In addition, the five behemoths vary in size; the GNR Plaza and Evergreen Mills behemoths stand more than 20 feet tall, whereas the behemoths in the Capitol Building and near Jury Street Metro are only about 12 to 15 feet in height, a little more than twice the size of a human.

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 some may already be dead or die in the process. On a nearby fountain in the square, you will also find a dead BoS member slumped on the fountain's rails in an almost picturesque position. The soldier will be in possession of a Fat Man and some mini nukes, which will be invaluable in bringing down the monster. However, keep in mind that the dead soldier will not be there if Sentinel Lyons isn't present in the battle.

Evergreen Mills
In Evergreen Mills, the raider-controlled train yard, a behemoth has somehow been captured and imprisoned by raiders, and contained in an electric fence. The fence's power source is a nearby generator. When approaching the area from the south, the generator can be easily destroyed with any ranged weapon. It should be noted that there is also a switch next to the generator. Once the electric gate is turned off, the mutant will rush outside and attack the raiders, killing most, if not all of them (most of whom are lightly armed with 10mm pistols, dependent on level). Nevertheless, their sheer numbers should be enough to decrease the behemoth's health by a considerable amount.

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 for the behemoth to die without any participation on your part. 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. One of the Talon Company mercenaries is equipped with a Fat Man and a few mini nukes as well, which makes them fully capable of killing the behemoth.

Takoma Industrial
A behemoth and several super mutants are located southwest of 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 much easier. This artillery will break after a few shots and need to be fixed with a Science skill of at least 33. After fixing it the artillery won't break again, so you can kill the behemoth without using any of your ammo (although it may take a while).

Jury Street Metro Station
This behemoth is located at a super mutant camp, marked by a group of wrecked train cars west southwest (Go west but only look south until you see it, it's more west than south and is easy to miss.) of Jury Street Metro Station. 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. Approach the carts and the behemoth will come for you. When he spawns, the behemoth may get caught up fighting Talon Company/Regulators (depending on karma)/other creatures near the Jury Street Station. Although, on odd occasion, the behemoth will appear before opening the cart. Also, upon opening the cart, it may take several minutes for the behemoth to spawn. take note on normal occasions that the behemoth will spawn instantaneously and appear directly behind you, so be prepared to jump from your seat.

Its been known that if you open the cart cage and let it respawn then load the game and go back to Jury Street Metro Station it will be waiting next to the cart cage.


 * Must open all 3 cages for him to spawn instantly

Appearances
Super mutant behemoths appear only in Fallout 3. It also appears in the Fallout New Vegas game files.
