Here's how it happened:
* During the battle: Tonks fought bravely, using her Metamorphmagus abilities to disguise herself and confuse her enemies. She ultimately met her end while defending Harry and the other fighters.
* Her killer: Tonks was killed by Bellatrix Lestrange, Voldemort's most loyal supporter and the wife of Tonks' husband, Remus Lupin. This duel was incredibly emotional, as the two women had a long-standing animosity towards each other.
* Her death scene: Tonks' death scene is particularly heartbreaking, especially for those who have been following her story. The image of her lifeless body lying next to Remus Lupin, who was also killed in the battle, is deeply poignant.
The circumstances of Tonks' death make it one of the most tragic moments in the Harry Potter series. It underscores the high price of fighting for what is right and serves as a reminder of the devastating impact of war, especially on those who love each other.
