Sometimes, new original characters are created in fanfiction to help Harry. These could be students from other wizarding schools who have unique skills. For example, a student from a school in a far - off land who has mastered a type of magic that is unknown in Hogwarts and uses it to help Harry in his fight against the dark forces.
The snake might use its ability to move stealthily. It could spy on the enemies for Harry Potter. For example, it can slither into hidden places where humans can't easily reach and gather important information.
Well, in many fanfictions, Susan Bones might use her knowledge of the wizarding world's lore. Since she comes from an old wizarding family, she could share some secrets that help Harry in his fight against Voldemort. For example, she might know about some hidden magical artifacts or spells that are not well - known.
One interesting plotline could be Harry getting help from a secret magical society that has been hidden from the wizarding world. This society might have unique spells and knowledge that they share with Harry to defeat Voldemort.
The snake's help could represent an unexpected alliance. In the Harry Potter series, snakes are often seen as symbols of Slytherin, which is usually at odds with Harry. So it's significant as it breaks the stereotype of enmity between Gryffindor (represented by Harry) and Slytherin.
If Harry Potter gets help from the Queen in fanfiction, the Queen could offer her strategic wisdom. Given her experience in ruling and dealing with various threats, she could help Harry plan his battles against Voldemort. She might also introduce Harry to a network of powerful Muggles who could support his cause in different ways, like providing financial aid for the Order of the Phoenix or helping to spread anti - Voldemort propaganda among Muggles.
Well, in this kind of fanfiction, Harry might receive some sort of otherworldly knowledge or power from Death. Maybe Death gives him the ability to see the true nature of dark magic, which helps him in his fight against Voldemort. It could also be that Death shows Harry the fates of different characters, guiding his actions to ensure the best outcome for the wizarding world.
Perhaps Death is a being from a different dimension in this fanfiction. It exists outside the normal rules of the wizarding world and has the power to interfere when it deems necessary. It could have its own motives for helping Harry. Maybe it wants to study the unique magic that Harry possesses, or it could be that there is a prophecy that ties Harry's success to the stability of the multiverse, and Death is simply acting to preserve the greater good.
Harry Potter is the key character as the title implies he is the one getting help. The goblins play a major role too. There could be a goblin leader, perhaps an old and wise one. Hermione and Ron may make appearances, but mainly it's about Harry's interaction with the goblins. There might also be some side characters from the goblin community, like young goblin apprentices who help Harry in unexpected ways.
Hagrid could be a great help. He has a lot of connections in the wizarding world, especially with those related to magical creatures. He might introduce Harry to someone who needs help with taking care of or studying magical beasts, and thus get Harry a job in that area.
