There's a possibility that it's from a new character introduced in the fanfiction. This character could be an old and powerful demigod who has been in hiding. They see Percy's potential and give him the new weapons as a means to help him save the world once again.
It could be Chiron. He's always looking out for Percy and the other demigods. He might have discovered some ancient weapons and thought Percy was the best one to wield them.
They could be a magical sword with the power to control water, like Percy's Riptide but with an added ability, such as being able to freeze water on command. This would give Percy an edge in combat, especially against fire - using enemies.
It could be Hephaestus. He is the god of blacksmiths and is known for creating amazing weapons and armors.
One of the most popular weapons in Percy Jackson fanfiction is Riptide. It's his trusty sword that can transform from a pen. In many fanfics, it has enhanced powers like being able to cut through any magical barrier. Another is Backbiter. It's a very interesting weapon as it has a double - edged nature. In some fan stories, it can be controlled by the wielder in unique ways. The third would be Tyson's hammer. It's a powerful weapon often depicted as being able to smash through almost anything in fanfiction. Writers like to give it extra abilities such as creating shockwaves when it strikes.
There are some really creative weapons in Percy Jackson fanfiction. For instance, a pair of gloves that when worn, can turn any object into a weapon by simply touching it. In some stories, there's a staff that can summon different mythical creatures to fight for the wielder. And a very unique one is a cloak that makes the wearer invisible to both mortals and immortals alike, which is often used in very interesting ways in fan - created stories.
I'm not entirely sure it can be simply defined as a human weapons fanfiction. While Percy Jackson does use weapons, the story is so much more. It's about his journey as a demigod, his relationships with other characters, and his discovery of his own identity. The weapons are just one aspect of the rich tapestry of the story. However, if we focus just on the weaponry part, there are many interesting human - like weapons like Annabeth's Yankees cap that could potentially classify it as having elements of human weapons fanfiction.
Riptide is the most notable one. It's Percy's sword which can transform from a pen to a sword. It's a very unique weapon and is crucial for Percy in his battles against monsters. Another one is Annabeth's Yankees cap which gives her the power of invisibility. It's a human - made item that has been enchanted and can be considered a weapon as it helps Annabeth in her sneaky missions.
The Titans could be the main antagonists. They might want to use the powerful weapons Percy is associated with to regain their power and overthrow the Olympians.
One possible plot could be Percy discovers an ancient weapon that has the power to control the elements. He then has to face off against an evil force that wants to use the weapon for destruction. Along the way, he teams up with his demigod friends and they all learn to master the weapon's powers together.
She could be the daughter of a minor god that hasn't been introduced much in the original Percy Jackson series. For instance, the daughter of Hecate. This would give her powers related to magic, which would be really cool in the context of the story. She could use her magic to help Percy and his friends in battles or to solve some of the mysteries they encounter.
There are many Percy Jackson fanfictions that incorporate a New York accent. Some might focus on how Percy's New York upbringing is reflected in his dialogue with that distinct accent. It could add a lot of authenticity and charm to the story. For example, when Percy is talking to his friends or getting into a scrape in the city, the accent can make his character come alive even more.
