Harry Potter: 10 Most Powerful Slytherin Students

The Lestrange name carries a lot of weight, and it's also one you should remember for later, wink, wink. This twisted family was prone to the dark arts and not fond of muggles, leading to a slew of unpredictable family members. But, one of the most notable was that of Leta Lestrange.

Albus Dumbledore himself referred to her as one of the cleverest students he ever taught, proving that she was something special from a young age. Although Leta only appeared properly in the less-than-stellar Crimes of Grindelwald, she still proved to be a very formidable witch with a great deal of skill and intelligence.

This witch managed to hold her own against the terrifying Grindelwald. Countless characters would have crumbled and cracked by simply standing near that monster, so Leta deserves heaps of credit for squaring up to him and protecting those she cared about.

Her final moments proved that she wasn't just powerful but brave too, and although she might not have come out alive, she destroyed the dark wizard's skull hookah and went out like a hero. That's got to count for something.
