Myrmyxicus

Myrmyxicuses were ancient, aquatic tanar'ri demons both awful to behold and devastating to encounter. The dreaded leviathans were infused with unholy energy, and ruled the depths of fiendish seas as terrible tyrants and masters of great slave empires.

Description
Myrmyxicuses were massive demons, measuring nearly long from head to tail. Their heads were like those of some prehistoric reptile of the sea, with tiny, black eyes and a fanged snout, as well as three pairs of curling, ram-like horns.

Their bodies were green and greasy, with a row of tall spines running down the back and a muscular, humanoid torso with four arms arranged symmetrically around the chest. Six tentacles like those of an octopus similarly ringed their waists, marking their long, eel-like lower halves ending in a tail with the mouth of a slavering lamprey at the tip.

Personality
The only true master of a myrmyxicus was itself, the foul creatures refusing to serve any other being, at least for very long. Few beings could match the horrible wrath of such creatures when they became enraged, and though tyrannical, some were known to infrequently commit random acts of violence on passersby before slinking back into the depths. They were incredibly knowledgeable and cunning creatures with a powerful force of personality, and were not to be mentally underestimated.

Abilities
Myrmyxicuses lacked the vast array of spell-like abilities seen in other powerful demons, though they did still have a potent retinue. They could replicate the effects of cause fear, charm person, charm monster, freedom of movement, telekinesis, teleport without error, and true seeing at will, and control water, control weather, greater dispelling, unholy aura, and unholy blight three times per day.

Instead of magic however, myrmixcuses utilized deadly and varied melee abilities. Their tentacles easily grabbed smaller opponents. Additionally, a bite from the myrmyxicus's tail could drain a victim's willpower. Even worse, those who attempted to fight a myrmyxicus would have to avoid the demon's tar-like blood, which was toxic to good-aligned creatures. Myrmyxicus were aquatic tanar'ri, able to travel through water much faster than they could on land. Oddly enough, they could also fly, albeit poorly, through natural magic.

Combat
Myrmyxicuses typically spread out their attacks between as many enemies as possible, only focusing on singular foes in the rare situations where an individual foe posed a significant challenge.

Most carried four huge, incredibly well-made scythes in order to empower them.

Ecology
Myrmyxicuses ruled portions of Abyssal seas from citadels of razor-sharp coral and fish skeletons.

Myrmyxicus demons were known to live in the Fated Depths.
