Half-god, half-man. It is what demigods are. The perfect balance between the divine and the mortals. The best of both worlds. But, as power goes, so comes challenge. Demigods have a challenging life, facing monsters and threats that come from the literal depths of hell.
They either rise above them or die trying. It is what makes them precious. It is what makes them special. That is what makes them… heroes.
And heroes, determine the course of history. They can challenge the power of fate. They can make waves by their very presence. They have the power to make the world… or raze it.
But with power, something more comes to mind.
It is said that a hero is defined by their actions, not the powers they are graced with. Yet, we all wonder what powers a hero has.
So, let us explore the powerset that a certain demigod child of the Olympians (or blessed by them) may have.
----------------------------------------------------------------------------------------------------------------
Zeus / Jupiter:
Zeus is the King of Olympus and one of the most powerful divine beings in the Greek world. He is the undisputed lord of the skies and has powers that blow mostgods and godesses out of the water.
He is one of the Big three and has fathered many children over the centuries. In recent times, he has two: Thalia and Jason Grace. A child, bearing his full powers, could be very lethal, and very dangerous. Their powers, if they receive all, will include:
Lightning control: A child of Zeus can shoot and summon bolts of lightning, which, at full power, can easily level a decent sized building— if not more. They can use it to electrocute enemies, and even reduce them to ashes, depending on circumstances
Aerokinesis: The ability to control air and winds is inherent to children of Zeus.
Atmokinesis: Children of Zeus can control weather to a certain extent.
Storm summoning: As an added benefit of Aerokinesis and Atmokinesis, they can also summon thunderstorms and tornadoes if enraged and skilled enough. Thalia, while not completely there yet, can summon winds fast enough to hinder enemies and deflect arrows if needed.
Ability to Fly: As shown many times in canon, Jason Grace can control the winds in order to fly.
Enhanced strength: As a child of the Big Three, they are better than normal demigods, leading to an enhanced physiology. While demigods are inherently better than mortal children in body, the children of Zeus take it a step even further.
Command / leadership: A lesser-known quantity that they passively inherit is the ability to command and lead groups, like their father leads Olympus. Thalia and Jason were both born leaders, as we have seen.
Ability to talk with birds, especially eagles
Poseidon / Neptune:
The god of the sea is the most powerful god on the Olympian council, with a vast array of powers, most rather destructive in nature. Poseidon represents the unstoppable power of the sea, its vastness and its limitless power, which he embodies. Most of his children do not receive his full set of abilities, with Percy Jackson being considered a general exception.
These powers are:
Hydrokinesis: The power to control water is something that all children of Poseidon, or for that matter, sea deities have. They can manipulate water and shape it to their will. This also extends to breathing underwater.
Geokinesis: Poseidon is also known as the Earthshaker, with the ability to cause Earthquakes and landslides. It is an ability his children seldom inherit. But Percy has, utilizing the ability in new and unique ways.
Atmokinesis: Poseidon is also the stormbringer, and his children can summon storms, which, while less precise than the children of Zeus (or Alexander), can be a lot more destructive.
Electrokinsesis: Through storms, they can also summon lightning.
Shapeshifting: Some have the ability to shift to animals of their wish, which is the one power Percy has not inherited from his father. A famous user would be Frank, who was a descendant of Poseidon.
Control ships with their will and have an inborn ability to navigate the seas and water bodies.
They also have perfect equilibrium. Whether on ship or anyother object, no matter how much it rocks or turbulence, children of Poseidon have perfect equilibrium on it.
They can also talk to animals like equestrian animals (like horses and zebras) and all sorts of aquatic life.
Hades / Pluto:
The third of the Big Three, Hades is the god of the dead, wealth, and the underworld amongst other things. His children are often considered dangerous, and have been on the wrong side of history many times. But when they're good, they're a force to be reckoned with. Nico di Angelo and Hazel Levesque are two prominent examples of his demigod children.
Powers include:
Necromancy: The ability to summon and command the dead. This includes raising skeletons, calling upon spirits, and banishing undead enemies.
Geokinesis: Like Poseidon, Hades has a deep connection to the earth, allowing his children to manipulate rocks, minerals, and precious metals, especially when birthed by his roman form.
Shadow Travel: The ability to teleport through shadows, which is both powerful and draining. Nico di Angelo uses this ability extensively.
Hell Fire Manipulation: A power generally not passed down to his children but one they could technically have.
Umbrakinesis: The more powerful children of Hades can control the shadows and darkness, using it as both an offensive and defensive weapon.
Death Sense: The innate ability to sense when someone is about to die or when a soul has passed on.
Curse Manipulation: The ability to inflict curses or hexes on others, a rare but potent power tied to the underworld. They are more magically inclined than most demigods, save for the children of Hecate herself.
Hestia:
The goddess of the hearth, home, and family is perhaps the most loved goddess in the entire pantheon, alongside being the eldest Olympian. Though she is a maiden goddess, and has never had demigod children, there are a select few, who are blessed by her.
Pyrokinesis: Complete control over fire, including Greek flames is the most dangerous power that those blessed by hestia wield. In addition, they are fire-proof and can stand immense heats without being harmed or burned.
Healing Flames: The ability to heal minor wounds or illnesses using fire.
Enhanced Cooking and Homemaking Skills: A seemingly mundane, yet invaluable, gift that ensures perfect meals and a comforting environment. This also extends to summoning homemade meals.
Protective Auras: Those blessed by her may gain the ability to create shields or wards that protect homes and loved ones.
Empathy: A heightened sense of understanding emotions and promoting peace among others. They can calm people and even break influences.
Hera / Juno:
As the goddess of marriage and family, Hera does not have demigod children but can bless individuals with powers reflecting her domains.
Massively Enhanced Strength and Stamina: Hera's champions have, in the past, exhibited extraordinary physical abilities in service of their tasks. Heracles was blessed by her and had immense strength. Strength enough to tear the Nemean lion in two amongst other feats.
Aura of Command: Those blessed by Hera often inspire loyalty and respect among others. They are the champion of the Queen of Olympus and royal command comes with it.
Immunity to influence: The champions of Hera are terribly tough to influence through magic or divine auras that many gods inspire. They can shrug off anything short of direct, divine action.
Magical Affinity: Unlike her siblings, Hera doesn't have an elemental domain, but she makes up for it with her magical knowledge which is only second to deities of Magic, which is passed down to her children / champion.
Protection Wards: The ability to create powerful protective charms or blessings for families and homes.
Divine Judgment: The ability to see the truth in disputes and mediate conflicts effectively.
Demeter / Ceres:
The goddess of agriculture and harvest, Demeter's children have a natural connection to the earth and its bounty.
Chlorokinesis: Complete control over plants, including rapid growth and manipulation of vines, flowers, and trees.
Geokinesis: Can control soil and it's fertility. Turning it into sand, making it barren etc.
Enhanced Farming Abilities: An instinctive understanding of agriculture, ensuring abundant harvests.
Weather Influence: A limited ability to influence weather, particularly to promote rain or sunshine for crops.
Communication with Nature Spirits: A deep bond with dryads and other nature spirits comes as a part of the deal.
Ability to Command Karpoi: They can command Karpoi, the nature spirit of fruits, vegetables and grains.
Ares / Mars:
The god of war embodies strength, aggression, and battlefield prowess. His children are natural-born warriors with abilities tied to combat and physical endurance.
Telumkinesis: Being a child of Ares would make them an expert in all weapon usage and they may even have some degree of magical control over them (e.g. they can turned arrows to rubber). Strong children of Ares, they are able to transform any object around her into any weapon and/or tool through sheer concentration and even place curses on their opponents' weapons.
Enhanced Physical Attributes: Ares' children are physically superior to many other demigods, built for prolonged battles and brawls.
Battlefield Intuition: The ability to read and adapt to the flow of combat, often predicting enemy moves.
Necromancy (limited): As children of Ares, they can summon the undead soldiers from losing side of any war. Still, there powers over the dead are far inferior to children of Hades.
Odikinesis: They have limited control and influence over the emotions of war (such as hate and rage). They would unknowingly use this ability to induce violent fights with other campers.
Powerful Scream (limited): As children of Ares, they are able to generate a powerful scream capable of causing their opponents extreme pain and discomfort.
Berserker Rage: In moments of extreme anger, they can enter a state of heightened power and durability, though it may cloud their judgment. Really powerful children of Ares can gain invulnerability in situations of extreme danger that manifests as a red glow.
Flames of War: This type of fire magic is incapable of anything but destruction. These flames are impossible to be used in forging cooking or even to give warmth in a cold night. The only thing they bring is death and destruction. Rarely passed down.
Athena / Minerva:
Athena is the goddess of wisdom, strategy, and warfare crafts demigod children who excel in intellect and planning.
Enhanced Intelligence: They have incredible problem-solving abilities and strategic thinking. They have an IQ that exceeds most humans on the planet. Children of Athena can see possibilities while in combat and their brain can work out numerous ways to take down opponents even way more powerful than they are. (Think danger levels of Batman with prep time.)
Combat Mastery: Skilled in martial arts and weapon use, particularly defensive and tactical combat. The children of Athena can gain expertise very quickly when handling weapons, even if they're foreign to them.
Craftsmanship: An innate ability to design and create tools, inventions, and structures. This also extends to gaining instinctive abilities like weaving, and instrument handling.
Knowledge Absorption: A natural ability to quickly learn and recall information. The more powerful children of Athena can even have a photographic memory.
Telepathy: Since Athena creates her children, rather than birthing them, she never hands out this ability. But if she did, her children would have the ability to read minds and influence thoughts, which would've made them VERY dangerous.
Flames of War: This type of fire magic is incapable of anything but destruction .These flames are impossible to be used in forging cooking or even to give warmth in a cold night. The only thing they bring is death and destruction. One thing Ares has her beat in, is the control over these conceptual flames, because for Athena, everything is a calculation whereas, war is unpredictable. Since she herself doesn't have much control over it, she doesn't pass it to her children as well.
Artemis / Diana:
The virgin goddess of the hunt and moon does not have children but blesses young women who join her Hunt.
Enhanced Agility and Speed: The hunters of Artemis have exceptional reflexes and the ability to move silently through the wilderness.
Archery Proficiency: Being the handmaidens of the greatest archer in the world, they gain a mastery of the bow and arrow, often surpassing any mortal or demigod with little effort.
Wilderness Affinity: The hunt often stays in forest, and all skills that one needs comes instinctively, be it survival, the ability to navigate forests, and also, the ability to communicate with the wild.
Heightened Senses: Enhanced hearing, vision, and tracking abilities.
Lunar Affinity: Those blessed by her have increased physical attributes under the moonlight. The fuller the moon, the greater their power.
Zoopathy: Can talk with wild animals to some extent.
Immortality (Conditional): Huntresses stop aging, be immune to diseases and remain immortal as long as they serve Artemis. This can be given by any god and is not limited to Artemis.
Apollo:
The god of the sun, music, and healing has children with a wide array of artistic and life-giving abilities.
Photokinesis: The more powerful children of Apollo can control light and have the ability to create blinding flashes or concentrated beams. Some, through history, can shoot beams of light through their eyes.
Healing Abilities: The power to heal others using divine energy or sunlight. They are natural doctors.
Disease and Plagues: Very rare, even more rare than Prophecy powers. Some children have the ability create diseases and plagues.
Archery Proficiency: Mastery of the bow and arrow, second only to Artemis. But one power the children of Apollo, or his most powerful children anyway, have is to enchant the said arrows to create flashbangs, sonic bursts, or even bio-weapons.
Music Mastery: An innate talent for music and poetry, often capable of inspiring others or influencing emotions. They can also use music to curse others, as demonstrated in canon. This also extends to whistling supersonic and ultrasonic noises, that can kill monsters.
Lie Detection: Some children inherit the ability to detect lies.
Mental Manipulation Resistance: Apollo is the God of Reason and Divine Knowledge. His children are resistant to mental manipulation like Dionysus' kids or like Hera did with Percy and Jason. (Resistant because you don't expect them to be able to be immune to a god's attack.)
Prophecy: Some children inherit the ability to receive visions of the future.
Aphrodite / Venus:
The goddess of love and beauty blesses her many children with charm and charisma.
Bellesakinesis: They had the ability to manipulate and control beauty in both themself and others. They can alter their appearance and physical features. They can also control things related to beauty like clothes, jwellery and makeup.
Enhanced Beauty: A radiant appearance that draws attention and admiration.
Hydrokinesis: In ancient times, Aphrodite was worshipped as a Goddess of Sea and Seafaring, though in recent times this aspect is mostly forgotten but her children could potentially inherit these powers.
Aerokinesis: Aphrodite is daughter of Ouranos, the Primordial deity of sky. Her children could potentially inherit the powers to control air.
Atmokinesis: Aphrodite is daughter of Ouranos, the Primordial deity of sky. Her children could potentially inherit the powers to control weather.
(Note: These powers would be nowhere near as strong as Zeus or Poseidon, unless she gained worship for it.)
Magical Potential: Children of Aphrodite have great magical potential, especially for illusions if used in conjunction with Charmspeak, though rarely realised.
Relationship sense: The children of Aphrodite can sense relationships and love.
Rose growing: The children of Aphrodite can produce roses out of thin air. Grow and control rose plants.
Hephaestus / Vulcan:
The god of fire and craftsmanship creates children with unmatched ingenuity and resilience.
Pyrokinesis: Control over fire, often used in forging or combat. Very rarely inherited.
Physical Strength: They often possess enhanced strength.
Technokinesis & Machinery Mastery: They can intuitively understand, fix, or manipulate any machine or device, often creating advanced automatons.
Enhanced Craftsmanship: A natural talent for building, repairing, and creating tools and weapons.
Enchantment: While there skill in other magical field is average but they can enchant their creation very well.
Heat Resistance: High immunity to extreme heat and immunity to burns from lava.
Hermes / Mercury:
The god of travelers, thieves, and commerce, Hermes' children are quick, cunning, and resourceful.

Enhanced Dexterity: Exceptional hand-eye coordination and reflexes.
Communication Skills: Fluent in multiple languages, including divine tongues.

The god of wine and revelry grants his children abilities tied to madness and vitality.
Chlorokinesis: Control over grapevines and plants associated with winemaking.
