Well, it could be that the author made the dragon extremely powerful. Maybe it had some unique abilities or was of a super - rare and dangerous species that was too much for Harry to handle. For example, it might have had impenetrable scales and a fire so hot it could break through any magical shield Harry could conjure.
The author might have set up a situation where Harry was caught off - guard. Perhaps he was distracted by something else, like trying to save his friends at the same time. So, when facing the dragon, he couldn't fully concentrate on the battle and made a fatal mistake.
The author could also have set up a situation where Harry was alone and without his usual support. For example, his friends were incapacitated or separated from him. In this vulnerable state, the troll was able to overpower him. In the fanfiction world, this kind of isolation can often lead to a character's downfall, especially when facing a dangerous adversary like a troll.
Well, perhaps the author thought that facing a dragon was an insurmountable challenge for Harry. Dragons in the Potterverse are extremely dangerous creatures. Maybe Harry underestimated the dragon's power or was caught off - guard in a moment of vulnerability, leading to his death.
His friends would be devastated. Hermione, for instance, would likely feel a great sense of guilt. She might think she could have done more to prevent it. Ron would be angry and grief - stricken at the same time. They would have to reevaluate their lives and their fight against the dark forces without Harry.
His friends would be devastated. Hermione would probably be in deep mourning. She had been through so much with Harry, and his death would leave a huge void in her life. She might even blame herself for not being able to help him.
It could be that the dragon was an egg he found by accident. He, being curious and having a soft spot for magical creatures, took the egg and hatched it, thus becoming the owner of the dragon. In the wizarding world, there are often unclaimed or lost magical items and creatures, and Harry might have just stumbled upon this dragon egg.
If Harry Potter were to fight a dragon with fire in a fanfiction, he might first need to find a source of magical fire. This could be a special wand or an enchanted object. Once he has it, he would have to strategize. He could try to direct the fire at the dragon's vulnerable spots, like its eyes or underbelly. But he would also need to be careful not to get burned by the dragon's own fire.
In Harry Potter fanfiction, death can be protective in a rather complex way. Sometimes, when a character dies, it sets off a chain of events that ultimately protect Harry. Consider a situation where a wizard close to Harry is killed by Voldemort. This could lead to an outpouring of support from the wizarding community for Harry, making it harder for Voldemort to target him directly. Additionally, the death of certain magical creatures might release powers or magic that then shields Harry. For example, if a phoenix dies, its final burst of magic could be diverted to protect Harry, given the strong connection phoenixes have with the concept of protection in the Potterverse.
In many fanfictions, Harry might use his powerful spells like the Stunning Spell or the Killing Curse if the story allows for such dark magic use. He could also use his intelligence to outwit the dragon, perhaps finding a weakness in its armor or behavior pattern and then using a well - timed spell to defeat it.
Some writers justify it by saying that Harry is a descendant of a powerful ancient magical line that was long forgotten. This hidden heritage unlocks his godlike powers as he grows older and discovers more about his past. For example, he might find out that his ancestors made a pact with some powerful magical beings, and the powers are now passed down to him.
A possible justification could be a deep exploration of Harry's post - traumatic stress. Writers might think that after years of fighting and losing so many people, Harry could reach a breaking point. But really, the Harry Potter we know from the books has a strong will and a support system that should prevent such a tragic end. So, these justifications seem more like attempts to create shock value rather than staying true to the character's nature.
