One idea could be that Severus, with his potions expertise, is recruited by the Bond - like organization in a world where magic and espionage co - exist. Harry, being a key figure in the wizarding world, gets involved too. Maybe they have to work together to stop a dark wizard who is collaborating with a group of evil non - magical villains.
Perhaps Severus and Harry are sent on a mission to infiltrate an enemy base that is protected by both magical and technological means. Bond - style gadgets and wizardry combine as they face numerous challenges. Harry uses his Gryffindor courage and Severus his Slytherin cunning to get through the various traps and enemies.
One possible plot idea could be Harry growing up with a conflicted identity. Since Tom is often associated with dark magic and Severus has his own complex past, Harry might struggle to come to terms with his heritage. He could be shunned by some in the wizarding world who fear his connection to Tom.
Severus would be his usual brooding and sarcastic self. His distrust of others might initially cause friction with Bond, who is used to working in a team. Harry, on the other hand, would be more open - minded. He might be in awe of Bond's suave and confident nature at first. But as they get to know each other, Severus would start to respect Bond's skills and Bond would come to understand Severus's complex past and motives.
One idea could be a story where Harry, Draco, and Severus are forced to work together on a dangerous mission to save Hogwarts from a new dark threat. They start off distrusting each other but gradually learn to respect and rely on one another.
One idea could be that they start off as enemies but are forced into a marriage by some magical law. As they live together, they gradually discover each other's hidden depths and develop a grudging respect that turns into love.
One idea could be a trainer who discovers a new Pokemon with an extremely powerful and unique Battle Bond ability. For example, it could be a Pokemon that not only powers up but also changes form in a completely unexpected way when the Battle Bond activates. Another plot could involve a trainer who has a difficult relationship with their Pokemon. Through the development of the Battle Bond, they learn to understand each other better and become a stronger team. A third idea is a story set in a tournament where the Battle Bond becomes a crucial factor. Trainers have to figure out how to trigger it at the right moment to gain an edge over their opponents.
In a more complex plot, it could be set in an alternate universe where Severus and Harry are on the same side from the start. As part of a team - building exercise of sorts, Severus uses tickling as a way to break the ice with Harry and the other young wizards. This leads to a series of adventures where their new - found camaraderie is tested and strengthened through various challenges, with the tickling incident being a recurring theme that is both humorous and a bonding factor.
One idea could be that Voldemort discovers the Infinity Stones and tries to use their power to conquer both the wizarding world and the Muggle world. The Avengers, with the help of Harry Potter and his friends, must stop him. They could combine magical spells with superhero powers to create unique battle strategies.
One idea could be that Voldemort teams up with a powerful Marvel villain like Thanos. This would force the Avengers and the Harry Potter characters to join forces. The Avengers could bring their strength and high - tech weapons, while the Harry Potter characters use their magic. Another plot could be that a magical artifact from the Harry Potter world is lost in the Marvel universe and both groups have to search for it. Maybe it has the power to destroy both universes if misused.
One idea could be that Voldemort somehow makes an alliance with Loki. The Avengers would then have to team up with Harry, Hermione and Ron to stop them. They could combine magic and superpowers in battles. For example, Iron Man could use his technology to analyze and counter some of the dark magic spells while Harry uses his Patronus to protect the group from Loki's illusions.
Well, for a Harry Potter and Naruto crossover fanfic, a cool plot could be that there is a dark force emerging that is a combination of Voldemort's magic and the Akatsuki's evil intentions. Harry Potter and Naruto then join forces. They start by training together, with Naruto teaching Harry some basic ninja moves like tree - walking to improve his physical abilities, and Harry teaching Naruto some basic spells for protection. Along the way, they gather their friends from both worlds, Hermione and Sasuke for example, to fight against this new threat.
