~Resistance and Physical Output: It can withstand the hottest or coldest inhabited planetary environments, able to easily outlast and outperform any Earthly life form known to science. Its body temperature adjusts to match its surroundings, with the aid of specialized glycoproteins in both its fluids and body which produce immensely powerful antifreeze molecules. The only organism that approaches (but does not exceed) the Magna Pater's vitality is the tardigrade, a micro-animal able to withstand 6,000 times atmospheric pressure, endure 1,000 times the lethal radiation that a human can, and immediately undergo reactionary chemobiosis to become immune to deadly toxins. The Magna Pater has five pseudohearts behind its circulatory system, the only effective way of killing it being the destruction of the brain, which is buried beneath layer after layer of thickly wadded muscle and cartilage. Like a snake, any limbs separated from the Magna Pater's nerve endings will proceed to react to stimuli and be capable of independent motion for up to two hours. Most often this results in the severed limb maintaining a 'death grip' on something it has captured, or attempting to capture whatever touches it, via a reaction similar to the Palmar Grasp reflex found in babies. If the Magna Pater's head is severed, it can retain consciousness for up to two hours as well due to its self-controlled metabolism and ability to survive without oxygenated blood.
Its body is even naturally insulated against electricity, to the point of shrugging off multiple lightning strikes during an electrical storm. Sticking a claw into a wall socket gives it about as much of a buzz as an expired can of Red Bull. It processes pain in a manner entirely different from Earthly creatures so that it doesn't experience physically or mentally distracting negative sensations. It knows when it's been hurt, and the knowledge itself is sufficient to influence its decisions.

It can physically dominate any creature in the animal kingdom, able to casually strangle elephants to death, separate their vertebrae, and twist their heads off, or yank the limbs off polar bears with only slight difficulty. It can run down a cheetah the way a cheetah runs down a gazelle, using the phenomenal might of its tail and arms to propel itself. It can sustain a high rate of strenuous activity for months on end and can fight without limit so long as it has a food source to draw energy from. As for the Magna Pater's physical durability, even without contracting its muscles to harden itself its body is tougher than an industrial tractor tire as per the physiology required to thrive in the deepest parts of the ocean and in space, withstanding a minimum of 1,000 times atmospheric pressure. When its muscles are contracted to full hardness, it can endure 6,000 times atmospheric pressure at the cost of its mobility being reduced to no more than a sixth of its maximum efficiency. It takes roughly three seconds for the Magna Pater to harden itself to this extent, and another three seconds to return to its standard physiology. It can isolate and contract individual muscles to harden specific points.

~Its dermal Lorenzini papulae function as electroreceptors and touch receptors, with twenty times the sensitivity of a human hand. It uses them for electrolocation to find the bioelectric fields of targets immune to sonar and infrared, detect electrical signals in muscles (permitting it to respond near simultaneously to the motions of its prey), follow hydrodynamic or aerodynamic trails, and to circumnavigate the globe. The range for detecting life forms via electrolocation is 1,200 meters, and the range to read their muscles is 600 meters. In regards to following dynamic trails, its range is 2,000 meters.

~Keen hearing and sonar. It's echolocation has a maximum distance of 6,700 meters and can detect objects moving at half the speed of sound. Its hearing is so good it can locate a victim even through miles of dense forest and with its back turned. Anything faster than its echolocation it can sense almost instantly via air pressure gradient.

~Lungs: The Magna Pater has three crude lungs, whose purpose is not respiration but to aid in the generation of sound.

~Life: It can survive in any sort of atmosphere which supports life, or even in the vacuum of space. It gains energy from a form of oxygen independent phagocytosis, digesting biological matter to power its body instead of breathing.

~Stealth: Its mucous gums up and muffles any minor sounds it may make when sneaking, and the Magna Pater is utterly immune to any magical or supernatural detection that doesn't naturally or scientifically originate within the five known senses. That is to say, it cannot be located via any kind of sixth sense. One may still detect it supernaturally, so long as said form of detection is directly based from sight, smell, hearing, taste, and touch. Sensory fields relying on electricity, magnetism, chi, telepathy, and the like are all wholly ineffective, even if the field is translated into one of the five senses by proxy. Sonar can detect the Magna Pater, because it directly relates to hearing. Seeing through the mind's eye, however, does not count as a direct correlation to sight. Rather than resulting in a blank spot in the midst of such a field, it would simply be as if the Magna Pater was never there.

~Heat pits: Can detect all forms of heat and energy, similar to infrared in snakes. This includes light itself. The heat pits are located on the inner linings of its mouth, nose, and ears.

~Fluke: The broadhead fluke at the end of the Magna Pater's tail measures six inches in length and four in width. It can narrow down to a stabbing point or flatten out almost to the sharpness of a blade. Just like the rest of the Magna Pater's body the fluke can soften or harden, and when hardened it can resist pressures upwards of 6,000 psi. At full swing it can gouge sizable chunks out of an oak tree and skewer a grown man like a fish on a pike.

~Tongue: Can draw in blood through a wound like an industrial vacuum cleaner, enabling it to drain a human body as quickly and thoroughly as a dehydrated fat kid with a juice box at lunchtime. The tongue itself is a powerful muscle that can choke victims to death, tipped with a hypodermic-like tip made of the same chitin as its claws. It can also squirt, inject, or spray pressurized blood and saliva, or launch its tongue out like a harpoon (in the manner of a chameleon) at speeds rivaling Major League baseball pitches.

~Natural weapons: Its teeth and claws are composed of a complex chitin and protein polymer, harder and sharper than a Humboldt squid's beak, which can pierce modern body armor. The Magna Pater wields a bite force of more than 15,000 psi, twice that of the strongest recorded bite measured from a Nile crocodile. Its broad, spade-shaped molars and canines are perfect for shearing through bone and muscle. Its tail has around 90,000 muscles, flexible enough to delicately pick up small pebbles, strong enough to grind masonry stone to powder, and fast enough to accelerate to whip-like striking speeds, enough to break the sound barrier at the tip.

~Can freely bend its entire body like rubber or stiffen to become hard. It lacks bones, instead maintaining its shape through different varieties of tensile muscle and cartilage. It's entirely multi-jointed and able to twist any part of its body 270 degrees in circumference. It can stretch itself within reason, potentially gaining several extra inches of reach in a pinch, as well as squeeze into any opening that it can fit its head through.

~Capable of entering a state of metabolic stasis which can last for decades. It retains spatial awareness during this "hibernation" and can awaken at will.

~Sense of smell: It can track down others thousands of kilometers away just by smelling them on the clothing of its prey.

~The Pull: The Magna Pater and the places it most often visits bear a quality that faintly arouses a victim's morbid curiosity when nearby. This doesn't work if one is aware of the monster's presence. As an example, were the Magna Pater to be waiting outside of a locked window, the victim may feel vaguely compelled to go to said window and look out, but not unlock the window after sighting the horror beyond it. The monster can decide whether or not a victim feels the "Pull". It has scarcely any effect on those with a strong will and a firm grasp of what is real, since the Pull is predominantly meant to snare children.

~Intelligence: Is highly sentient. It has more than two millennia of experience in its current form as a highly prolific interdimensional serial killer, can grasp (but not speak) all languages, and never makes the same mistake twice.

~Can quickly regenerate from wounds by consuming blood and flesh. The amount of mass healed is proportionate to how much is consumed, I.E one pound of food to replace one pound of damaged tissue. It can selectively heal different parts of its body, and any excess food it eats is stored for later regeneration. It can hold up to 110 kilos of food in its stomach.

~Wings: The membrane of its wings is far tougher than Kevlar and can completely stop bullets from a .950 JDJ hunting rifle. The maximum wingspan of each arm, when stretched, is comparable in surface area to a queen size blanket, and the membrane itself is twice as thick as a padded backstop mat. The membrane is composed of specialized nerve and muscle fibers which can expand, contract and move freely with incredible strength, more than enough to hold and even break the bones of virtually any mortal creature it catches. As could be assumed from the crushingly powerful phalanges ridging the wings, they aren't at all meant for flight but to allow the monster to both guard against particularly dangerous attacks and to catch and smother prey. It can secrete vast amounts of mucous from the membrane just as it can from every other part of its epidermis.

~Dream Feelers: The Magna Pater's feelers function to receive dreams rather than such things as scents or sounds. When the feelers are fully extended, the Magna Pater can view the dreams of every creature on the planet. It can influence dreams, but the influence decreases the further one is from the Magna Pater. When within a thousand miles it can only very slighter alter a dream, almost imperceptibly. At three-hundred miles it can turn a good dream into an uncomfortable one, or make an uncomfortable dream into a nightmare. When the target is within a hundred miles, the Magna Pater can easily cause nightmares, and even night terrors, but can't entirely influence the contents of the nightmares or dictate exactly how they proceed. It can also wipe the memory of said dreams before the victim wakes up, and tell with perfect precision when the victim will awaken. Over the course of several months and with continuous pestering, it can impress early onset Alzheimer's and dementia onto a victim at this range.
When the Magna Pater is thirty miles or closer, it can manipulate dreams entirely and force the victim to witness any scenario it desires. Unless the target has immensely potent and self sustaining mental defenses set up to stop planetary-level psychics (psychics who can, in the least, influence events from across the distance of a large diameter planet), the nightmares may unequivocally result in the victim reverting into either a permanent vegetative state or violent lunacy, immediately losing their mind from fright as the Magna Pater fully claims them as a part of its transcendental nightmare. It can also inflict them with overnight Alzheimer's and dementia, entirely deteriorating their mental faculties over the course of a single dream. The Magna Pater's range may be limited to a thousand miles, but the concentration is in excess of planetary psychics. Furthermore, when the Magna Pater is in a state of stasis its reach is doubled.

~Sound: The Magna Pater can emit infrasonic and ultrasonic frequencies with incredible potency thanks to its specialized lungs and vocal organs. When just below the range of human hearing or at the limit of its vocal range, fifteen kilometers, it can make a typical male human feel uneasy, off-balance, and slightly nauseous. Within eighty yards it can match the frequency of a victim's eyeballs to create temporary blindness or gray spots, damage eardrums, induce vomiting, cause difficulty breathing and heavy drowsiness (can force an average man into unconsciousness after just few minutes), and severely affect balance to the point of the victim having great difficulty staying on their feet. At ten yards the effects can rupture eyeballs and eardrums, or even cause lethal cerebral hemorrhaging when used on the average male human.

~Stomach: As evidenced by its ability to immediately digest whatever it eats, the Magna Pater's stomach utilizes a lethal super acid that can dissolve any organic matter in mere seconds. Though typically this acid remains in the stomach, as the Magna Pater cannot mass produce its acid as easily as its saliva or mucous, it still weaponizes this asset. It can turn its stomach inside out to engulf difficult prey and digest them externally, a feat most consistently displayed by certain species of sea snails and starfish.

~Sex: The Magna Pater is able to mate with any organism larger than thirty kilos, regardless of gender or lack thereof. Its young are hundreds of malformed, inch-long worm creatures that die hours after squirming out of the victim's body through the skin. This ability has no biological prerogative, only instituted for the sake of cruelty.

~Mucous: The Magna Pater's most versatile and powerful asset. Its body mucous and saliva contain anticoagulant, cytotoxic, and bufotoxic properties. Those whom it bites or claws will suffer gradual necrosis, unstoppable bleeding, and fast-acting, nightmarish hallucinations. Supernatural forms of healing are drastically hindered where the Magna Pater's juices are concerned, the anticoagulant preventing even magic from clotting or regenerating blood cells, although the monster is immune to its own toxins.
The speed at which the bufotoxins take effect depends on how close the wound is to the head. As an example, were it to jab one of its claws into a large man, it would take roughly several minutes for the poison to take effect from a foot wound, and several seconds if the wound was near the head. Were the Magna Pater to inject a victim with its tongue (which can mass produce large amounts of saliva), even a blue whale would succumb in less than a minute if it were pierced in the center mass. The toxin has a median dose of (LD50) of 1.3–2.1 ng/kg, making it a top contender for the most potent toxin in the world.
The viscosity of the mucous can be regulated, allowing the Magna Pater to be extremely slippery or adhesive. The mucous at its stickiest can bind even the strongest of victims, partially deaden the momentum of heavy impacts, and tear off the skin and muscle of any victims that are unfortunate enough to come into contact with it.
The mucous is flame-retardant, boasting a stupidly high melting point and repelling most structural changes instituted by outside forces. So long as it has the mucous to do so, it can endure military flamethrowers, oil fires, and even a napalm bombing. The mucous is scentless and masks odors, provides an extraordinarily high resistance to electricity due to its non-conductivity and insulating properties, and bears an extremely low freezing point to act as extra insulation against low temperatures. When at its stickiest, it bonds on a molecular level to whatever it touches. The Magna Pater's body is the sole exception, the only matter that the slime doesn't fuse molecules with. Instead the slime clings to the monster like an exceptionally potent form of superglue, and is released from the Magna Pater's body when more layers of mucous are secreted beneath to uproot the first layer, in a word, "sloughing" off the slime.

It can convert and secrete up to twenty percent of its body weight in mucous at a rate of 16 liters per second, provided the entire body is producing the mucous. It becomes significantly faster when empty and can regain the weight by eating.
