The Darkhold is basically a dangerous magical manuscript in Marvel Comics. It can grant immense power but at a huge cost. It's been a major plot device in many stories, causing all sorts of trouble for heroes and villains alike.
Another theme is teamwork. Given their abilities, they can be a formidable team. Fanfics often show them coming together to face threats that neither could handle alone. For example, there are many stories where they fight against interdimensional villains. This theme also allows for character development as they learn to trust and rely on each other.
One great Wanda and Dr Strange fanfic is 'Mystic Encounters'. It explores an alternate universe where their powers interact in unexpected ways. The story has a great plot that keeps you hooked from start to finish.
The 'Darkhold Spider - Man Story' could be a really interesting and complex one. The Darkhold has a long history of causing chaos and trouble in the Marvel universe. When it comes to Spider - Man, it might change his perception of things. For example, the Darkhold could make him see his friends as enemies or vice versa. It could also enhance his powers in some strange and uncontrollable ways. Spider - Man would then have to figure out how to deal with these changes while still staying true to his values. Maybe he teams up with other heroes who have knowledge about the Darkhold to overcome the challenges it presents.
Common themes include dealing with the consequences of their powers. Both characters have had instances where their powers got out of control. Fanfiction often delves into how they manage this, whether it's Strange trying to control the time - related consequences of his magic or Wanda handling the chaos her magic can create. Another theme could be their place in the greater superhero community, and how they interact with other heroes through their relationship with each other.
Yes, there are many. You can find some on fanfiction websites like Archive of Our Own. Some stories might explore their relationship in different ways, like teaming up against a powerful enemy or having a deep friendship that develops over time.
