Flash can help in Spiderman fanfiction if he were to, say, be in the right place at the right time and notice something that benefits Spiderman. But he typically hurts. His pride and need to be the center of attention often lead to him putting Spiderman down. This can be a big problem for Spiderman, who needs to focus on saving the city. Flash's actions can sometimes cause Spiderman to lose his focus, which could have serious consequences in a fight or when dealing with a dangerous situation.
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 reason could be a misunderstanding. Maybe some villain has tricked Hulk into believing Spiderman is a threat. For example, the villain might have faked some evidence to make it seem like Spiderman was planning something bad against Hulk or his friends.
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 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.
The plot could start with Spider - Man getting seriously injured in a fight against a powerful new villain. Daredevil then steps in to protect Spider - Man while he recovers. He wards off other villains who try to take advantage of Spider - Man's weakened state.
He might also use his webs to his advantage. He could try to web up Hulk's hands or feet to slow him down. Or he could create a web shield to block some of Hulk's attacks. For example, if Hulk throws a big rock at him, Spiderman could use his webs to create a net to stop the rock.
In some fanfictions, Tony might help Spiderman by providing him with advanced technology. For example, he could give Spiderman a new suit with enhanced features like better web - shooters or stronger defense mechanisms. This would help Spiderman in his battles against various villains.
Well, it could be a story where they team up to fight a common enemy. Maybe a villain who has the ability to manipulate time or something. Spiderman could use his intelligence to come up with a plan, and The Flash could quickly execute it with his speed. They would learn from each other's strengths and weaknesses along the way. For example, Spiderman could teach The Flash about using the environment to his advantage, while The Flash could show Spiderman how to move even faster in a fight.
In fanfiction, if Percy hurts Flash, it could be due to Flash's constant bullying. Percy, being a demigod, has powers and a short temper at times. Flash might push him too far, and Percy could accidentally use his powers, like controlling water to trip Flash or something. It would be a moment of self - defense for Percy, and it could lead to a lot of drama in the Camp Half - Blood setting, with other campers having to take sides or deal with the consequences of such an incident.
He could lose his friendship with Spiderman, if Spiderman survives. Their relationship would be severely damaged, and it would be hard to repair the trust between them.
Another way is through isolation. Ego could isolate Peter from his friends and allies on his planet. This makes Peter feel alone and more dependent on Ego, which can be a form of psychological harm.
