I am Alcyoneus, the bane of Pluto, the new master of Death!
~ Alcyoneus to Hazel, Frank and Percy


Alcyoneus is the eldest of the giants spawned by Gaea to overthrow the Olympians after they deposed the Titans. Created to battle Hades, he was the first giant his mother tried to revive by manipulating Hazel Levesque, but the demigod sacrificed herself to stop the giant's complete revival. Alcyoneus was only revived decades later, and was the one responsible for keeping Thanatos, the god of death, imprisioned.

IntelligenceAs a being made to match Hades, the god of the underworld who deposed the titans along with his brothers Poseidon and Zeus, Alcyoneus is a dangerous and powerful opponent, and has only be beaten by extremely powerful demigods, like Hazel Levesque and Frank Zhang, being worthy noticing that they had help from Arion, one of the fastest horses in the world. Alcyoneus is powerful enough to completely destroy an entire roman legion composed of veteran demigods, despite they having the Eagle of Jupiter.

Weaknesses: Alcyoneus's body is made of precious stones and metals, because of this he is vulnerable to Hades and his childrens's power of manipulating metals and stones. Unlike the other giants, once Alcyoneus is out of his territory, he can be beaten and killed, not necessarily by a demigod and a god working together.

Key: Full power | Depowered

Notes: The idea that only a god and a demigod may defeat him is likely a No Limits Fallacy and it's far more likely that any sufficiently powerful character would be able to defeat him.

The Percy Jackson deities don't create constellations by materializing entirely new stars, but by increasing the luminosity of existing stars, hence their current rating.
