It depends on your perspective. Some might think so, while others might have doubts based on various factors like the hero's actions and character development.
Hermione is often the real hero in fanfiction because of her intelligence. She uses her vast knowledge to solve problems that others can't. For example, in many scenarios, she's the one who figures out complex spells or discovers hidden secrets in the wizarding world.
The selflessness. In a real hero story, heroes often put others' needs before their own. For example, firefighters rush into burning buildings without hesitation to save people they don't even know. This selfless act is very inspiring.
In the fanfiction, Hermione might be portrayed as more central to the action compared to the original series. Maybe she takes on more solo heroic deeds without relying as much on Harry or Ron.
One of the main themes is friendship. Hiro and his friends work together as a team, relying on each other's strengths. For example, GoGo's speed and Wasabi's precision are crucial in their battles.
