A great fanfiction idea could be that the Marauders (James, Sirius, Remus, and Peter) had an encounter with a Hydra - like group in their school days. This encounter could have shaped their future actions and relationships. Or perhaps Dumbledore had a past encounter with Hydra and had to keep it a secret to protect the wizarding world. This could add a whole new layer of mystery to his character in the context of the fanfiction.
In some Harry Potter fanfictions, 'hydra' could be a magical experiment gone wrong. A wizard or witch might have been trying to create a new form of life or a powerful spell, and instead, they ended up with something similar to a hydra. It could also be a name given to a place, like a hidden lair or a dangerous area filled with all sorts of magical perils that the characters need to navigate through.
A great plotline could be that the Hydra Wand was stolen from a hidden wizarding vault long ago. The current owner, who doesn't understand its full potential, is using it for petty crimes. Harry, Ron, and Hermione stumble upon this and realize that they need to track down the wand's true history. As they do so, they uncover a web of secrets and lies within the wizarding community that dates back generations.
There's 'Hydra - Harry's Hidden Side'. This story delves deep into how Harry's life could change if he was part of Hydra. It shows his struggle between his old values and the new, darker world of Hydra. The plot is full of twists and turns that keep readers engaged.
One interesting Avenger - Hydra fanfiction could be about a scenario where a Hydra agent has a change of heart and secretly helps the Avengers. This could add a lot of intrigue as the Avengers are initially suspicious but gradually come to trust this former enemy.
One interesting dragon hydra fanfiction could be about a young hero's journey to slay the hydra - dragon hybrid. In this story, the hero might face many challenges, like the multiple heads of the hydra breathing different elements such as fire, ice, and lightning.
In such a fanfiction scenario, Harry Potter might be forced to use his magic in new and unexpected ways to try to escape. Maybe Hydra would be interested in his magical abilities for their own evil purposes, like using his magic to power some sort of dark weapon.
One idea could be that Harry discovers he is a Hydra Animagus in a very dangerous situation. Maybe when he is facing Voldemort and his Death Eaters, he suddenly transforms into a Hydra, taking them by surprise. The multiple heads of the Hydra could have different abilities, like one head spits fire, another can freeze things, and it gives him an edge in the battle.
Yes, there are some. One might involve a 'hydra' as a guardian of a powerful magical artifact. The heroes have to find a way to defeat it to obtain the item. Another could be where a 'hydra' is part of a dark wizard's army, causing chaos in the wizarding world.
One possible fanfiction could be about the origin of the Hydra Wand. Maybe it was created by a dark wizard who was inspired by the mythical Hydra. The wand could have special powers like being able to split into multiple smaller wands in a battle, each with its own unique spell - casting ability.
One idea could be a crossover where Hydra discovers the wizarding world in the Harry Potter universe and tries to use magic for their evil purposes. The Avengers somehow get wind of this and team up with Harry Potter and his friends to stop Hydra. Maybe they have to battle magical creatures that Hydra has corrupted with dark magic.
