King Poseidon is a creature in the Kaijudo: Rise of the Duel Masters series.


Hundreds and hundreds of feet long, this is the largest known leviathan in the entire Water civilization. It takes a massive amount of mana to summon, and is only seen on very rare occasions, in situation of dire need... As large as entire cities, King Poseidon wanders the oceans of Water alone. He prefers solitude, emitting sonic blasts into the pitch darkness of Water’s deepest oceans. He only ever sets his course back toward the center of Water when a major battle is underway, using his massive size and control over sonic waves to fight back.


Reef Prince Glu-urrgle once used the Helm of Ultimate Technology to summon King Poseidon so that it could help Ray fight against the Magma Dragon Melgars that Alakshmi had summoned by using the Sword of Fiery Cataclysm.

In the second season, King Poseidon is used by the Choten to start a war between Water and Fire.
