Poseidon wakes up in the modern era by accident. Gemini Saga had a twin brother named Kanon, who was pure evil at heart and tempted his brother constantly to go over the dark side and seize power in Sanctuary by killing Athena. Saga incarcerated his brother a bit too late since his&nbsp;poisonous&nbsp;words had the desired effect. Kanon was left to die in the prision of Cape Sunion in which he struggled for years to survive, until one day using his cosmo-energy he manges to break a wall containing Poseidon&amp;#8217;s Trident which had his power sealed by Athena. As soon as he makes this amazing discovery he&amp;#8217;s sallowed by the floor and driven to the Undersea Temple.
Kanon wakes up to find himself in a new world over the ocean, destroyed in the last holy war. while he explores this Undersea Temple he finds himself in Poseidon&amp;#8217;s Sanctuary where his soul rests along his seven general. Kanon breaks the seal in the urn containing&nbsp;Poseidon&amp;#8217;s&nbsp;soul and quickly&nbsp;proceeds&nbsp;to interrogate Kanon, who identifies himself as &amp;#8220;Sea Dragon&amp;#8221;. He reveals to the God that Athena has just come back to earth, and that it would wise to be prepared for a new holy war. Poseidon agrees, but his slumber must be concluded, so he&amp;#8217;ll hide in the body of the Solo family youngest heir, Julian, who has the royal blood&nbsp;necessary&nbsp;to carry his power until he and Athena come of age and wage war.
Kanon agrees to these terms and feels the power of Poseidon leave his temple and go across the undersea temple making it come to life again and restoring his&nbsp;grandeur, he also grants to the renegade saint the Scales of Sea Dragon (similar to a Saint&amp;#8217;s Cloth) and makes him second in command of The Undersea Temple Army. Poseidon, like every other deity on the series is a massive powerful character, he has complete control over the sea currents, the&nbsp;rains&nbsp;and every other natural phenomenon in the planet, he also manipulates energy projection either&nbsp;through&nbsp;his mind, his trident or his bare hands. Julian Solo has a hold of all of these powers while Poseidon is still asleep. The god is not awakened by Kanon when the time comes, and his real power surfaces when he faces the&nbsp;Bronze&nbsp;Saints in their last stand..
