Mirelurk King

Mirelurk Kings are seemingly the brood leaders of the Mirelurks.

Physiology
Mirelurk Kings are tall, about a foot taller than an average-sized man, and physically similar to a human.

Mirelurk Kings are fiercely aggressive, although not quite as resilient or powerful as Mirelurk Hunters, they are still fast enough to pose quite a threat. They are fairly weak to concentrated fire, and are only really dangerous if encountered alongside other Mirelurks.

Unique to the Mirelurk species, Mirelurk Kings also project a sonic attack from a distance, much like the Robobrains, which causes moderate amounts of damage, and possibly the character's head to become crippled.

Given the humanoid shape of Mirelurk Kings, and some of the concept art, it is entirely possible that Mirelurk Kings are more than leaders of Mirelurk broods, but an evolutionary leap all of their own, seen in artwork using clubs and other tools much like neolithic man. It may also be worth noting that in the hardcover artbook that comes bundled with the limited edition there are artist notes that make mention that the Mirelurk Kings may have an evolutionary tie to snapping turtles native to the local rivers.

Loot
Mirelurk Kings contain Softshell Mirelurk Meat in addition to Mirelurk Meat, which is an even more powerful healing agent than ordinary Mirelurk Meat.

Location
Mirelurk Kings can be found mainly in submerged water environments. One such area is in the entry to the Rivet City Bow (The snapped off last part of the aircraft carrier). Other locations that Mirelurk Kings can be found in include Rock Creek Caverns, Mirelurk Nesting Hole, in the water by the Abandoned Car Fort, in the top right corner of the map (confrim? might be spawn spot?), the Reactor Room area of Vault 92, the Sunken Chambers during the Oasis quest and the submerged area underneath the Anchorage War Memorial. They can also rarely appear from a river.

Note:Mirelurk Kings can attack while swimming.

Trivia
The Mirelurk King possesses a striking resemblance to the Creature from the Black Lagoon, and an even greater resemblance to Abe Sapien from the Hellboy comics.

Bugs
You can reverse-pickpocket a grenade into a Mirelurk King for a stealth kill. However, this oddly results in you getting negative Karma. We currently do not know why this is, though perhaps the game sees this method of killing them rather inhumane? Another reason might have something to due with their humanoid structure and appearance.
