Radscorpions are large, mutated scorpions commonly found in and around abandoned structures. They originated from the North American Emperor scorpion, which were prolific in many pet stores at the time of the Great War. They have since mutated to become much larger, faster and more venomous than ever before.
Radscorpions sport highly venomous stingers, the ability to burrow underground in seconds, powerful claws, and durable exoskeletons. Unlike Mojave or Capital Wasteland variants, the Commonwealth does not feature radscorpions that occupy a similar size category as giant radscorpions.
Radscorpions have either migrated to the Commonwealth from the southwestern United States, or mutated independently from emperor scorpions kept as pets before the war in a similar manner to ones located in different areas of the continent.
Radscorpions are fast runners, extremely aggressive, extraordinarily well armored and will use their powerful claws and poisoned tails to attack enemies quickly and relentlessly; capable of dealing a large amount of physical and poison damage in only a few hits. With their ability to burrow underground and traverse large distances seemingly instantaneously, retreating from an encounter is often impossible. Their only weak spot is their relatively small face. Deathskull radscorpions are easily one of the most dangerous creatures one can encounter while exploring the Commonwealth, completely capable of killing the player character in even the highest grades of power armor.
Due to their claw and poisonous sting attacks as well as their great maneuverability, radscorpions are powerful melee fighters that should be dealt with preferably from a distance, or with specialized equipment if a direct confrontation is necessary. If attacked from afar, they will immediately burrow and emerge close to the player character, often in melee range, provided the ground type can be navigated through by them, so it is possible to avoid being caught unprepared by standing on rocks, or metallic/wooden surfaces before attacking. Weapons with armor piercing mods as well as the legendary modifier "Penetrating" can help improving the damage output against their armor reinforced exoskeletons.
Radscorpions are mostly found within the Glowing Sea. They can be found on occasions in other areas of the Commonwealth as well. Radscorpions can be pacified through the Wasteland Whisperer perk.
Very rarely, an encountered radscorpion will be non-hostile to the player character and will go about their business as if the player character wasn't there. It will still attack other enemies on sight, such as raiders and super mutants. However, it will still attack the player character if they remain in close proximity for too long.
The standard variation of its kind, radscorpions can be difficult to fight at low levels since they have a quite high amount of Hit Points and powerful attacks compared to other creatures. These creatures are found all over the Glowing Sea, and one can be found at the Old Gullet sinkhole by triggering the cymbal-clapping monkey nearby.
Glowing radscorpions have been exposed to massive amounts of radiation, and as a result their body is seen glowing green. Besides the increased Hit Points and damage, glowing radscorpions will deal radiation damage to anybody nearby.
Similar to the Fallout 3 rendition, Albino radscorpions have a noticeable white color, which makes them easier to see due to their distinctive body color. These enemies may prove to be quite dangerous as they have a high amount of Hit Points and powerful melee attacks.
A rare but dangerous radscorpion, deathskull radscorpions have a noticeable reddish color. These enemies are extremely powerful as they are more resistant than a standard behemoth, and their attacks combined with the additional poison damage may result in them easily wounding or killing the player character. These types of radscorpion level with the player character, thus making them impossible to pacify. The higher the level of the player character, the higher the odds of this type of radscorpion appearing.

↑Chris Avellone, Fallout Bible 1 - "The radscorpions are a result of a combination of radiation and the FEV virus, and Razlo in Shady Sands is correct - they were originally Emperor Scorpions that have grown... big."
