Another plot might involve Harry being summoned to the past right before a major event in wizarding history, like the creation of a certain dark object. He then tries to stop it from being made, which means he has to face some very powerful and dangerous wizards from that era. His presence in the past also causes some misunderstandings as people don't know who he really is and what his intentions are.
Hermione is often a common character. Since she is Harry's closest friend, she usually plays an important role in helping Harry navigate the past. She might use her vast knowledge of magic and history to figure out why Harry was summoned and what they need to do next.
One great fanfiction could be 'The Summoning of Sebastian by Harry Potter'. In this story, Harry might summon Sebastian for a special mission. Maybe it's to solve a mystery in Hogwarts that only Sebastian's unique skills can help with. It could involve a lot of magical elements like complex spells and ancient artifacts.
There is also a possibility that it's an unknown powerful wizard from a far - off land. This wizard has heard of their reputations and summons them to learn from them or to ask for their assistance in a matter that is crucial to his own land's magical stability.
There's also 'Summoned to a New Destiny'. In this fanfic, Fem Harry is summoned by a powerful magical force. It delves deep into her character development as she tries to adapt to the new situation. The author does a great job of portraying her struggles and growth. It's really a must - read for fans of this genre.
Often, heroes from other well - known fantasy worlds are summoned. For example, characters like Aragorn from 'The Lord of the Rings' might be summoned. His skills as a warrior and leader could be very useful in the Harry Potter universe. Another common summoned hero could be Conan the Barbarian. His brute strength and survival instincts would make for an interesting addition to the story. Sometimes, heroes from modern superhero stories are also summoned, like Batman or Superman. Their unique abilities and moral codes would create a lot of interesting scenarios in the wizarding world.
They might be summoned by a powerful magical creature. This creature could be in need of their help to solve a problem in the magical world. It could be a dragon that has lost its way or a unicorn that is being hunted by dark forces, and they are the only ones who can save the situation.
Another way the 'Harry Potter is summoned' concept works is when a magical being with great power summons him. This could be a powerful wizard from another land or a magical creature like a phoenix or a centaur. They might summon Harry because they sense his unique magic or because they believe he has the ability to solve a problem that they can't. For example, a centaur might summon Harry to help deal with a dark magic that is corrupting the forest it guards.
Well, perhaps Harry could face unexpected magical challenges. The Goblet might summon him for a task that is far more dangerous than the Triwizard Tournament in the original story.
One great 'Battle Hardened Harry Potter Summoned' fanfiction is 'The Summoned Hero' on FanFiction.net. It shows Harry in a whole new light, having to face challenges that make him even tougher than in the original series.
