Percy would probably use his powers over water to his advantage. Maybe there are large lakes or rivers in the Jurassic times and he can control the water to create barriers or distractions against the dinosaurs.
The characters from Percy Jackson would have to learn quickly. Percy could communicate with some of the sea - based dinosaurs, which might help them get food. Grover, with his nature - sensing abilities, could detect approaching danger like stampedes or large predators. And Annabeth would study the Jurassic environment to figure out how to best survive, like finding caves for shelter and using vines as traps or for climbing.
Well, it could be a really interesting and terrifying addition. Maybe it could be some kind of ancient monster that was locked away long ago in the world of Percy Jackson. It could be released by some dark magic or an evil demigod. The xenomorph's ability to adapt and its deadly nature would make it a formidable foe for Percy and his friends.
Percy Jackson would probably stand out in Forks. He has this whole demigod aura and his powers are quite flashy compared to the more low - key vampires and werewolves. But he might adapt by using his wits. He could blend in by pretending to be a normal human, but his constant awareness of possible threats (which in Forks are vampires and werewolves instead of Greek monsters) would make him seem a bit paranoid to the locals.
Percy's water - controlling abilities would be unique in Asgard. He could use it for defense and offense. For example, he could create water shields or water whips to fight against enemies. His ability to breathe underwater might not be as useful in Asgard directly, but it could come in handy if there are any underwater areas or if he has to deal with water - based magic there.
One interesting crossover could be Percy using his water powers to deal with the large bodies of water in the Jurassic times. Maybe he helps some dinosaurs cross a flooded area. Another could be him facing off against a sea - dinosaur using his sword and powers.
One interesting crossover could be Percy using his water powers to deal with the prehistoric water sources in the Jurassic era. Maybe he helps some dinosaurs get water during a drought.
In the context of Jurassic fanfiction, Percy's water - based powers could be both a defense and a tool for exploration. He could use water currents to quickly move around the park, avoiding the dinosaurs. His power to heal himself with water could also come in handy if he got injured during an encounter. Additionally, he could manipulate water to create distractions for the dinosaurs. For example, he could make a large water splash to startle a group of Velociraptors, giving him time to escape. His powers would give him an edge in this prehistoric and dangerous environment.
He could be a wildcard. His lack of emotion would make his actions hard to predict. He might join a quest just because it seems logical, not because of any emotional attachment to the cause. For instance, if there's a quest to retrieve a powerful artifact, he'd analyze the risks and rewards and decide based on that, not on things like pride or loyalty like the demigods.
Ice powers could fit in by being a new type of power that challenges the existing power dynamics. For instance, in battles, they could change the terrain by creating ice ramps or freezing lakes for strategic advantages.
Percy is a brave and loyal character. His loyalty would mesh well with the flock's sense of unity. He's also quite adaptable, which would help him get used to the flock's way of life. His sense of humor might lighten the mood among the flock members.
