Was the protagonist of Harry Potter fanfiction supposed to defeat Voldemort or be invincible?

😋I recommend the following two novels to you: Hogwarts: The Pet Master and Hogwarts 'Explosive Genius. The protagonist of " Hogwarts Pet Master ", Kerry Black, wanted to train all kinds of magical creatures to defeat Voldemort and become the pet master of Hogwarts. However, she did not have a cheat code and was born with the ability to sense biological affinity. The plot of the book was compact and exciting. Seamus Finnigan, the protagonist of Hogwarts 'Explosive Genius, became a slightly famous explosive genius. He worked in all kinds of magic explosions and was entangled by all kinds of magical and dangerous things. The plot of this book was also very exciting. It included the protagonist's explosive skills and the fantasy elements of the Harry Potter world. I hope you like my recommendation.😗
