Hagrid helps Harry in fanfiction by introducing him to new allies. He has a wide network of friends in the magical world, both human and non - human. He could introduce Harry to a centaur who has valuable prophetic abilities, which could assist Harry in making important decisions in his fight against Voldemort or other villains.
One way is through her unwavering belief in him. Ginny always had faith in Harry, and in fanfiction, this can be a huge factor in his recovery. When Harry doubts himself, Ginny's belief gives him the confidence to keep going and start to heal.
One way Ino helps is by being a source of emotional support. Her friendship with characters like Sakura can be a stabilizing force. In some fanfictions, she might offer advice on relationships or personal growth.
Often in fanfiction, Dumbledore helps Harry understand the nature of Voldemort's soul - splitting into Horcruxes. He may guide Harry in the search for these Horcruxes. Dumbledore could also use his own powerful magic to shield Harry from Voldemort's attacks, at least until Harry is fully prepared for the final confrontation.
Dobby sometimes helps Harry Potter in fanfiction by summoning other magical creatures to assist. For example, he could call upon friendly centaurs or house - elves from other families who are sympathetic to Harry's cause. This creates a sort of magical alliance around Harry, which is really cool. Dobby's social network among the magical beings is something that is often explored in interesting ways in fanfiction.
One main way is through his magical knowledge. Harry has learned a great deal during his time at Hogwarts, and this knowledge can be applied to building projects in fanfiction. Another way is his influence. As the Boy Who Lived, he can persuade others to contribute to Hogwarts' development. Also, his courage allows him to take on challenges related to building, like exploring dangerous areas of the castle to find ways to improve it.
Another way dragons might help Harry in fanfiction is through a magical bond. If Harry forms a bond with a dragon, he could draw on the dragon's strength and power. This could enhance his own magical abilities, allowing him to perform more powerful spells or withstand stronger attacks. Also, the dragon could communicate with Harry telepathically, sharing important information and strategies for dealing with difficult situations.
Dumbledore often makes an appearance in such fanfiction. He might be the one who gives Harry and Hagrid their special tasks or provides guidance. Another popular character could be Hermione. She could be the one who helps Harry and Hagrid with research or comes up with clever solutions when they are in a bind. Ron might also be there, adding some humor to the story and being Harry's loyal friend as usual.
One way Marge can help is by being a plot device. Her presence can force the wizard characters to be more cautious about using magic, which adds tension to the story. For instance, if they are in a situation where Marge is nearby, they have to hold back their magical abilities, and this can lead to some interesting and suspenseful scenarios.
In Spiderman fanfiction, Flash might help when he gets involved in a situation where his actions indirectly aid Spiderman. However, he hurts a great deal. His attitude can make Spiderman feel isolated. Since Spiderman already has a lot on his plate, Flash's negative behavior adds to the stress. It can also make it harder for Spiderman to maintain his secret identity as Flash is always looking for ways to expose any weakness in Peter Parker.
One way could be through telepathy. In fanfiction, Harry might be able to directly communicate with the minds of animals and tell them what to do. For example, he could tell a group of birds to fly in a certain pattern to create a distraction.
