Well, first of all, Nico di Angelo has his own set of powers and a complex backstory from his original world. If adopted by Batman, he would have to adapt to a completely different environment. Batman would probably be strict but also caring. He'd try to understand Nico's powers and how to use them for good in Gotham. Nico, on the other hand, might struggle with the new rules and the lack of the magic - filled world he came from. But over time, they could form a strong bond like a father - son relationship and face all kinds of challenges together, from the Joker's schemes to other mystical threats that might seep into Gotham.
One possibility is that Nico, with his powers over the dead, could really freak out Batman at first. Batman is used to dealing with normal criminals and the occasional super - villain with scientific powers. Nico's dark and otherworldly abilities would be something completely new to him. Maybe Nico would mistake Batman for some sort of undead creature at first because of his all - black costume and brooding nature.
One of the main antagonists could be the Penguin. He is a classic Batman villain and his criminal activities in Gotham would put him at odds with Batman and Nico. Additionally, if Nico's presence in Gotham attracts unwanted attention from the underworld of his own world, perhaps a powerful demigod or a group of magical creatures could also become antagonists. They might not understand or respect Batman's territory and would try to cause chaos. Another possibility is Ra's al Ghul. His long - term plans for Gotham and his extreme views would surely clash with what Batman and Nico are trying to achieve.
Well, if Nico di Angelo meets Voldemort in a fanfiction, it depends on the writer's take. Nico could see Voldemort as just another evil entity to oppose. He might use his connection to the Underworld to his advantage. For example, he could summon some undead creatures to fight against Voldemort's Death Eaters. Voldemort, on the other hand, would probably view Nico as a strange and unexpected foe. He might try to use the Killing Curse on Nico, but Nico's ability to disappear into shadows could make it difficult for Voldemort to land a hit.
The storyline could involve Nico adjusting to life in the Avengers' compound. He might use his powers from the Percy Jackson universe in unique ways to help the Avengers in their battles. For example, his ability to control the dead could be used to gather intel from fallen enemies.
Another storyline could involve Nico being on a quest in his own world, but it somehow intersects with Gotham. For instance, a powerful magical item has been stolen and ends up in Gotham. Nico follows it there and meets Batman. At first, they don't see eye to eye as they have different methods. But as they face challenges together, such as fighting off the villains who also want the item, they start to understand and trust each other more. This could lead to a long - term friendship or at least an alliance where they help each other out in future situations.
Nico's powers could also bring a new element of mystery to the Avengers. His abilities are not like the typical superpowers the Avengers are used to. This could lead to new training regimens and strategies. The Avengers would need to figure out how to incorporate his powers into their existing battle plans. And Nico himself would have to learn how to work within the group's dynamics, which could be a bit of a struggle at first given the differences in their power sources and fighting styles.
In a fanfiction where Nico di Angelo meets Dumbledore, there are numerous possibilities. Nico might be initially distrustful of Dumbledore, given his own experiences with authority figures. However, Dumbledore's calm and kind demeanor could gradually break down Nico's walls. Dumbledore could introduce Nico to the wonders of the wizarding world, such as spells and magical artifacts. Nico, in turn, could show Dumbledore some of his demigod abilities, like shadow - traveling. Their meeting could also lead to a cultural exchange of sorts, with Nico learning about Hogwarts and Dumbledore getting a peek into the life of a demigod.
In such a fanfiction, there could be an epic battle. Nico's powers from the Percy Jackson universe might clash with the Winchesters' hunting skills. Maybe they initially misunderstand each other, thinking the other is a threat. But then they could realize they are all fighting against some form of evil and team up. For example, Nico could use his ability to control the dead to help the Winchesters deal with a horde of zombies, while the Winchesters could teach Nico some of their combat tactics against demons.
In the fanfiction, Nico might find himself in some of the Marauders' pranks. Since the Marauders are known for their mischief, they could include Nico in one of their elaborate schemes against the Slytherins. Nico, being from a different background, might have a different perspective on these pranks and could either enhance them or try to stop them depending on his moral compass at that moment.
Well, Nico could use his powers to surprise the Avengers. Maybe his shadow - traveling ability would come in handy during a battle, like he could quickly transport himself and some Avengers to strategic locations.
