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.

Abilities
Myrmyxicus demons were powerful, aquatic tanar'ri, but they were much slower on land. Oddly enough, myrmyxicuses could fly, albeit poorly, through natural magic. Like all demons, they spoke the Abyssal language and possessed darkvision; as tanar'ri, they could telepathically speak to any creature with a language.

Myrmyxicuses lacked the array of spell-like abilities seen in other powerful demons, instead utilizing deadly and varied melee abilities. Their four arms could wield enchanted, unholy scythes, and 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.

The myrmyxicuses did possess a few spell-like abilities, being able to 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 each per day.

Ecology
Myrmyxicuses were arrogant demons who refused to serve others, instead ruling portions of Abyssal seas from citadels of razor-sharp coral and fish skeletons.

Myrmyxicus demons were known to live in the Fated Depths.
