Hogwarts: The Strongest Animagus Ever

Charlotte traveled to the wizarding world, but became a test subject of a dark wizard and was forcibly injected with thunderbird blood.
Just when he was about to die, the god-level transformation wizard system awakened.
The next moment, Charlotte transformed into a thunderbird, becoming the master of storm and thunder, and razed the black wizard's laboratory to the ground in an instant.
From then on, Charlotte embarked on the path of a legendary A**ger.
Transformed into a fire demon, the devil's fire that destroyed the world made the red dragon retreat.
Transformed into a nightmare, he can easily invade other people's dreams and fabricate dreams to make people fall asleep in them.
Transform into an immortal phoenix, gain immortality, and no longer fear the Avada Kedavra curse.
Many years later.
When Voldemort's water Death Eaters attacked Hogwarts, Charlotte transformed into a Titan and punched out, destroying the world.
Dumbledore: "Charlotte is the most outstanding student in the history of Hogwarts. He has surpassed Merlin, the god of magic. The Dark Lord is no match for him!"
Voldemort: "Charlotte is the real devil. I am just a reptile in front of him..."
