Sirenkind in Equis throughout the world are a species all in themselves unique as they are potent, though the males are often the most genetically malleable. Using their gifts from the ocean god known as Poseidon, they strike head first into predators and enemies who’d bring harm to their pods, following the directions of the alpha Matriarch for a coordinated success.
 
Male sirens are called sirons, built to impede, made to attack, and designed to withstand an immense amount of damage before falling to their injuries. To lay a little pipework, sirens are rare for a number of reasons though the primary are predatory species such as the Hammerhead Moray and Ocean Dragons who actively prey upon packs either as a staple part of their diet or a booster to their overall range of food. Not all creatures and monsters are capable of falling to a sirens song, therefore, for as long as any siren as known the males exist as the backup plan.
 
While girth, muscles, and dense bone structure give a siron their ability to fend off most attackers, it all lies in their reinforced craniums to handle much of the grunt work. Any siron had an incredibly dense bone matrix similar to rams or buffalo where they can sustain multiple head on collisions without falter. Due to their own predatory nature of fish, mollusks, and anything in the oceans they have an ample supply of nutrients and minerals to maintain such a natural defense. With fangs suited to shredding into tissue much like a shark would, a siron will latch onto a portion of an aggressor and lash about till the damage is done or a hunk of meat is torn off.
 
Though their primary attribute is their cranial protrusions, sirons can be identified mainly by these bodily constructs that allow them to stay a foe in place or battle a rival for a female’s honor. Ranging from horns, battering rams, to impaling spikes a siron is not without some way of dishing out pain. Their muzzles are also modified from birth in accordance to their protrusions, some sporting razor sharp horns, others blunt caps for concussive strikes which all go to discouraging an Ocean Dragon, a deadly Deep One, or even a Hammerhead Moray from claiming a victim of their unit.
 
Their mouths alone are weapons themselves, with lips able to be pulled back to allow almost every tooth to be used in an assault or self defense. Unlike a siren who has limits to the extension of their jaws and lips, males have no problems widening their maws wide enough to hold two pony head at the same time. This helps to hurt armored enemies such as dragons, Tatzlworms, and the like using their powerful tails to push and pull with incredible power. The morphic phenotype can range from the standard to the bizarre, depending on what pod is being examined and where they reside some males have exhibited armored heads similar to their apex predator the Hammerhead Moray with a solid cranial cap of pure bone and spongy tissue for spearing and ramming. Needless to say, males often do the hunting for the pod, with their already capable bodies, tuna to porpoises, to whales and invertebrates nothing escapes the siron’s eyes and teeth. Though they do sacrifice themselves to feed a great devourer so the others may escape unharmed, these are one of the ultimate guards of nature in Equis.
