I found this story on fanfiction.net and decided to show it to the Wattpad community. All rights to the author of this fanfiction - Hans50 - from whom I got permission to post this story here. He's an awesome writer and you should go check out his account and his other story: Betrayed Son of the Sea. Perseus Jackson is trapped in Tartarus. After the council of the gods, save a few, betray and sentence him to eternal suffering, something happens to our hero that will change him forever. He is tortured and cursed. With a horrible curse placed upon him that turns him into the things that he hunts and despise, will he suffer in the pit or will he thrive? He is the Monster Shifter. (By the way, this is not a Percabeth story. Just a heads-up for the Percabeth fans.) DISCLAIMER: I don't own this story, Hans50 and Rick Riordan do.

On the moon, lived two 16 year old twin sisters. Amaranthine & Cerulean. Their parents, Mother Moon - Luna Azure & Father Sun - Sol Aubade. The beautiful teen sisters had element half sisters which lived on Earth. Amaranthine, Cerulean, and their element half sisters were assigned a job to pinpoint an evil sorcerer named Walter Vicks who wanted to dominate the sisters' home ( the moon ) and have the Earth under his fingers. His real name was Yoven Shakii but his disguise name was Walter Vicks. He ran across every continent, country, state of Earth, and all other solar planets in the galaxy, gaining its liberal power and learning Earth's weaknesses to take over. Yoven was quick moving and wasn't human. He was a serpent who took form as a regular man but had a dark and conniving spirit. Amaranthine, Cerulean, and their element half sisters would need to all ban together to take down a powerful monster hidden beneath a mask.
