Mirelurk King

Mirelurk Kings are presumably the brood leaders of the Mirelurks.

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

While not as resilient or powerful as Mirelurk Hunters, Mirelurk Kings are faster, and possess a species-unique ranged attack similar to that of the Robobrains. This "sonic" ranged attack - which cannot be used if the Mirelurk King's head is crippled - causes moderate amounts of damage, and can cause the player's head to become crippled.

Mirelurk Kings are fairly weak to concentrated fire, and are only really dangerous if encountered alongside other Mirelurks.

Loot
Mirelurk Kings contain Mirelurk Meat as well as the considerably more potent Softshell Mirelurk Meat.

Locations
Mirelurk Kings can be found mainly in deep water environments such as the following:
 * The entry to Rivet City's Broken Bow, near the snapped-off part of the aircraft carrier
 * Rock Creek Caverns
 * Mirelurk Nesting Hole
 * In the water by the Abandoned Car Fort
 * Around a pond directly west of the Republic of Dave
 * The Reactor Room area of Vault 92
 * The Sunken Chambers of Oasis
 * The submerged area underneath the Anchorage War Memorial.

They can also emerge at random from a river.

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 (which results in negative karma because pickpocketing any object results in negative karma).
