Percy's power over water could potentially be combined with Sirius' Animagus form. For example, Sirius in his dog form could swim faster in water controlled by Percy. Also, Percy could use water to create distractions or barriers in a fight, while Sirius could use his werewolf - fighting skills and speed to take on enemies that get past Percy's water defenses.
One idea could be that Percy discovers his connection to Sirius Black during a quest in the demigod world. Maybe he stumbles upon some ancient prophecy that links the wizarding and demigod worlds through their bloodline. Another plot could involve Percy using some of the magic knowledge that might be passed down from Sirius' side of the family to defeat a new and powerful enemy that threatens both the wizarding and demigod realms.
Well, it could be really exciting. Maybe it starts with Percy being drawn into the wizarding world. Sirius, being a rebel and all, might be immediately intrigued by Percy's different kind of power. They could start off as wary of each other but then gradually form a bond as they realize they both have a strong sense of justice and a desire to protect the innocent.
One interesting fanfic could be where Percy Jackson somehow gets transported to the Harry Potter universe and meets Sirius Black. In this fic, they might team up to fight a common enemy, perhaps a dark wizard who has some connection to the Greek monsters Percy is used to. The author could explore how Percy's powers, like controlling water, would interact with the magic in the Harry Potter world.
Their relationship could develop through shared adventures. Maybe they start with a small mission together, like rescuing a group of people trapped by a minor villain. As they face challenges, they learn to trust each other more. Percy might share some of his demigod knowledge with Clint, and Clint could teach Percy some superhero - style combat tactics. Over time, they become like family, with Clint acting as a mentor to Percy in the world of superheroes.
The fanfiction could focus on Percy's relationship with Nick Fury. Maybe Fury is trying to keep Percy's identity as a demigod a secret from the rest of S.H.I.E.L.D. while also using his unique skills. Percy, on the other hand, might be struggling with the strict rules and secrecy of S.H.I.E.L.D. compared to the more free - flowing world of Camp Half - Blood. This could create a lot of internal and external conflict for Percy as he tries to fit in both worlds.
Yes, there might be. Fanfiction is a vast world where all kinds of crossovers are possible. However, the quality and popularity can vary greatly. You can start your search on major fanfiction platforms like Archive of Our Own or FanFiction.net.
One possible plot could be Percy using his demigod powers in a world that also has superheroes like Clint Barton. Maybe he teams up with Clint to fight a common enemy that is a threat to both the demigod and superhero worlds. For example, a powerful monster from Percy's world that has teamed up with a super - villain from Clint's world.
I really like the fanfiction 'Mystic Alliances'. In this one, Percy's powers interact in an interesting way with Jacob's wolf abilities. The story has a great plot that keeps you hooked from start to finish. It also develops the characters in a new light, showing how they grow and adapt in a combined universe.
One idea could be that Black Widow is somehow transported into the Percy Jackson universe. Maybe she has to team up with Percy and his friends to defeat a common enemy. Since she has her combat skills and spy training, she could offer a different perspective on battle strategies compared to the demigods.
