Long ago, back when the Titans were vanquished, back when the gods began to rule the earth, and back when Bikini Bottom was nothing more than an empty wasteland, chaos still brewed within the ocean like a boiling cauldron, spreading panic through every mortal's mind. No one knew where this chaos originated, let alone settled in the aquatic world, but all remembered the form it took itself in; a large, ominous beast, capable of making one's heart stop just by looking into its dark, blood-red eyes. It ruled a large portion of the sea except for a growing kingdom on the tallest mountain in it, but greed made it come after it, threatening the safety of its inhabitants.

King Neptune, the true ruler of the kingdom, knew this beast could not be stopped with his strongest weapon and symbol (the trident), so he set out to create a weapon of purity to rid of the beast's wicked soul. With the help of Cyclops, he created a weapon stronger than all the gods combined; it was a trident made not of gold, but pure, strong crystal found within the grandest of underwater volcanoes. With it, the ocean god defeated the beast, and peace spread throughout the land.

However, the impurities separated from the crystal trident formed themselves into a dark trident, and the vanquished beast used it to regain its power and shattered its opposite, hiding the pieces within an abandoned temple that not even the wisest could predict they were there. To this day, the pieces of the legendary Crystal Trident remained hidden.

But one day, the most unlikely of heroes, five friends with the purest of hearts, would soon yield its power and face against the greatest threat to ever come to their home...
