What are some interesting ideas for a Harry Potter and Shadow the Hedgehog fanfiction?

Well, perhaps in this fanfiction, Shadow the Hedgehog is on a mission to find a powerful magical artifact which he believes is hidden in the wizarding world. Harry Potter and his friends get involved when they notice strange things happening around Hogwarts. Together, they form an unlikely alliance. Harry uses his knowledge of magic and Hogwarts' secrets, while Shadow uses his super speed and combat skills to overcome the various obstacles and villains that stand in their way.

One idea could be that Shadow discovers he has vampire-like abilities after a strange encounter in a dark, enchanted forest. He then has to struggle with his new thirst for blood while still trying to protect his friends and the world from villains.

A great plot for Shadow the Hedgehog game fanfiction could involve Shadow's relationship with other characters. For instance, a story about how he forms an unlikely friendship with a young and naive creature in the Sonic world. He then has to protect this new friend from the chaos and danger that constantly lurks in their world. This would show a different side of Shadow, his more protective and caring side.

One interesting idea could be how the shadow clones are used in magical battles within the Hogwarts setting. They might be used as decoys to outwit opponents, like when facing Death Eaters.

One plot idea could be that Shadow and Amy are on a mission together to save Sonic who has been captured by a new villain. Along the way, they start to understand each other's motives and personalities better. Amy's positive attitude might start to rub off on Shadow, who is usually more brooding.

In a Harry Potter Shadow Wolf fanfiction, a great plot could be that the shadow wolf is a guardian of a secret passage in Hogwarts that leads to a place filled with powerful spells and potions. Harry stumbles upon the shadow wolf and at first is afraid, but then realizes it means no harm. The shadow wolf then shows Harry the passage. This could lead to Harry finding something that gives him an edge in his battles against Voldemort, like a spell that can nullify the Killing Curse or a potion that can heal any wound. It could also be that the shadow wolf has a past with one of Harry's parents, and through this connection, Harry learns more about his family's history.

One interesting plot idea could be the Shadow Lord being an ancient and forgotten dark wizard who is awakened in modern times in the Harry Potter world. He might start to gather dark forces secretly, and Harry and his friends have to figure out who this new threat is before it's too late.

Perhaps the Shadow Walker is a new character who has a connection to an ancient magic that Voldemort is also seeking. In the fanfiction, this could lead to a race between Harry and Voldemort to gain the power of this magic with the help of the Shadow Walker.

One idea could be that Shadow somehow gets transported to the My Little Pony world. He might initially be a bit of an outcast due to his different and edgier personality compared to the ponies. But as the story progresses, he could learn about friendship and harmony from them and in turn, teach them about his own values like loyalty and justice in a different sense.

I think Harry Potter himself would be very interesting. He has a whole new world to discover in the world of Shadow the Hedgehog. His reactions to the high - speed action, different technology, and the new types of enemies would be really cool to explore. Also, his magic would be a unique element in that world.
