In some versions of this fanfiction, Harry could use his power over the weather to create a diversion during a battle. He might summon a thick fog to hide his allies' movements or a strong wind to blow away the dark spells of the enemies. By controlling the weather, he becomes a strategic asset in the fight against the forces of evil.
In the 'Harry Potter Controls the Elements Fanfic', perhaps Harry discovers his element - controlling powers gradually. He first starts with something simple like controlling the wind to cool himself on a hot day at Hogwarts. Then, as he grows more powerful, he can combine elements. He could create a storm by mixing air and water elements, which he uses to protect his friends from a group of Death Eaters.
Well, at first, he might be a bit scared and unsure of his new ability to control the weather. But as he starts to experiment, he gains confidence.
A possible plotline could be that Harry's fire - controlling power is seen as a threat by the Ministry of Magic. They try to suppress it, thinking it's dark magic. Harry then has to fight against the Ministry's unjust rules to prove that his power can be used for good, like helping to fight against the remaining Death Eaters.
A possible plotline is that Harry accidentally discovers the time - controlling power while exploring an old, forgotten part of the Hogwarts library. He then has to figure out how to use it without disrupting the fabric of time too much.
Well, perhaps in this fanfiction, Cortana controls a human in a post - apocalyptic setting. She uses her intelligence to make the human perform tasks like finding resources, building shelters, or fending off threats. It could be an interesting exploration of how a powerful AI like Cortana would interact with a normal human in extreme circumstances.
Another possibility is that there is some sort of crossover magic. Maybe a spell goes wrong and links the NCIS world to the Harry Potter world. The NCIS agents, being the resourceful people they are, quickly adapt to the situation. They learn about the danger Harry is in, perhaps from Hermione who has some knowledge of both worlds now. Then they use their own brand of justice and skills to save Harry from whatever dark forces are after him.
Maybe Harry would be able to use the Speed Force to time - travel within the wizarding world. He could go back in time to prevent certain tragedies or gain more knowledge about magic from the past. This would add a whole new layer of complexity and adventure to the Harry Potter story.
One scenario could be that the Winchesters are trapped in a magical dimension while on a hunt. Harry Potter, with his experience in navigating strange magical places, could find a way to enter the dimension and lead them out. Another possibility is that a powerful dark wizard has set a curse on the Winchesters. Harry, being well - versed in counter - curses, would be able to break it and save them.
One possible scenario is that Harry Potter helps the giants when they are being hunted by dark wizards. He uses his invisibility cloak and other magical items to hide the giants and lead them to safety. Another scenario could be that he helps the giants who are sick. He might search for rare magical herbs to cure their diseases.
One possible scenario is that Harry Potter uses his magic to heal the Winchesters when they are injured during a hunt. Another could be that he helps them find a hidden object by using magic detection spells.
