He had the ability to create storms, earthquakes, floods, and droughts. Like many other gods, he had superhuman strength along with the capability to teleport and shapeshift.
POSEIDON was the Olympian god of the sea, earthquakes, floods, drought and horses. He was depicted as a mature man with a sturdy build and dark beard holding a trident (a three-pronged fisherman's spear).
Poseidon's strengths: He is a creative god, designing all the creatures of the sea. He can control waves and ocean conditions. Poseidon's weaknesses: Warlike, though not so much as Ares; moody and unpredictable. Spouse: Amphitrite, a sea goddess.
Poseidon, in ancient Greek religion, god of the sea (and of water generally), earthquakes, and horses. He is distinguished from Pontus, the personification of the sea and the oldest Greek divinity of the waters.
Poseidon was god of the sea, earthquakes, storms, and horses and is considered one of the most bad-tempered, moody and greedy Olympian gods. He was known to be vengeful when insulted. He is the son of Cronus and Rhea and was swallowed by his father along with Hades, Demeter, Hestia and Hera.
Like the other Olympian Gods, Poseidon possesses super-strength, super-speed, shapeshifting, immortality, and invulnerability. Poseidon can control the seas and all life that dwells within them.
Atmokinesis: As the God of the sea, Poseidon possesses the power to manipulate water, storms, and lightning, able to create strong waves and violent storms to bring the rage of the ocean upon those who anger him.
The trident is Poseidon's main symbol because its three-pronged fork resembles a fisherman's spear, which represents his power over the sea (Morford). It is also his main weapon because the trident gave him the power to exhibit violence or calm the water with a mere stroke (Morford).
Homer and Hesiod suggest that Poseidon became lord of the sea following the defeat of his father Cronus, when the world was divided by lot among his three sons; Zeus was given the sky, Hades the underworld, and Poseidon the sea, with the Earth and Mount Olympus belonging to all three.
Poseidon is a god in Greek mythology and one of the Twelve Olympians. He is one of the three most powerful Greek gods (along with Zeus and Hades) and rules over the ocean and all bodies of water.
God of War: Ascension
The Ice of Poseidon could also summon glaciers to damage foes and also had the ability to freeze enemies and then instantly killed them by shattering them.
The trident is the weapon of Poseidon (Greek) or Neptune (Roman), the god of the sea in classical mythology.
Poseidon's Secret is an Atlantean myth technology in Age of Mythology: The Titans that is available to worshipers of Theia and can be researched at the Military Barracks. Once researched, it increases the attack and movement speed of cavalry units by +15% and +10%, respectively.
Electrokinesis: Poseidon can generate and manipulate electricity. He used this power to help Hades in defeating Atlas. In God of War, he bestowed Kratos with a small portion of his electrokinetic power. In God of War III, he uses his trident to shoot bolts of electricity at Kratos and Gaia.
Semi-immortality: As a God, Poseidon is incapable of dying due to old age. He is very ancient, being older than the Big Bang (making him over 13.8 billion years old). Hydrokinesis: As the "God of the Seas", Poseidon possesses absolute control over divine water.
Hydrokinesis: As the Olympian God of the Seas, Poseidon has Nigh-Omnipotent control over all forms of water. He can control, create and manipulate water such as making an entire ocean into a puddle or creating tsunamis. He can use his control over water to create powerful water blasts at his opponents.
Two other gods that are somewhat equatable to Zeus are Poseidon and Hades, brothers of Zeus. Poseidon was the god of the seas, and Hades was the god of the underworld. Both of these gods had similar power to Zeus, but of them, Zeus was ultimately the most powerful.
In short, Zeus. He gathered the clouds and ruled the sky, so rain was under his control. Poseidon ruled over the sea rather then water and could control storms as long as it was over the sea.
In Greek mythology, Zeus is not killed at all. Zeus is king of the Greek gods and goddesses, a role he takes on after defeating his own father.
He had the ability to create storms, earthquakes, floods, and droughts. Like many other gods, he had superhuman strength along with the capability to teleport and shapeshift.
As his son Percy did in The Last Olympian and The Son of Neptune, Poseidon can create extremely durable water shields and huge solid constructs that obey his will.
Poseidon also had his own epithets or attributes and titles that he has or develops throughout Greek mythology. The symbols of the gods and their epithets represent their divinity and exceptional power. Poseidon's symbols include his trident, the bull, the horse, and even rocks.
Aerokinesis (limited): Poseidon can control the air in a limited way to accompany his storms. Geokinesis (limited): Poseidon has some control over the land, but less powerful than his older brother Hades or his grandmother Gaia.
Poseidon chose the water, Zeus the sky, and Hades the underworld. Poseidon's weapon is the trident, and he uses it to shatter any object and shake the earth, therefore causing earthquakes.
Short answer: It depends on who's myths you read. In Zeus-centric myths, Zeus would win as the myths make him out to be THE God. And everyone kowtows to him. In Poseidon-centric myths, we see Poseidon being stronger than Zeus and the above answer is just Zeus being egotistical.
