The Trident is the sea god Poseidon's weapon and his Symbol of Power. With it, he has the ability to control the ocean, shake the earth, and shatter any object. It can also project beams of blue light that can transform targets or even outright destroy what they hit. It is shown that when he hits a sea monster, it transforms into a goldfish. When he hit a squid "it dissolved like food coloring", and he told Percy, "'If I hadn't looked before I blasted, you would be a puddle of sea water". It is also said that earthquakes are caused when Poseidon strikes his trident into the ground. That is why Poseidon is called "The Earthshaker". It was forged by sea demons known as Telekhines. It is a three pronged spear with energy bolts surging through it. To regular mortals, it appears as a surfboard, fishing rod or ice cream, when he is by the beach due to the Mist. There is an attachment for Poseidon's trident on his throne, where one would expect a fishing pole on a mortal fisherman's chair.
