Pureblood Who? The Most Powerful Muggle-Born Wizards in ‘Harry Potter’ Ranked
March 18, 2026 | by admin

The Wizarding World is casting a spell on us all over again! With a highly anticipated Harry Potter TV series officially headed to Max in , Potterheads are diving back into the lore of the Boy Who Lived.
While certain “pureblood” families in the franchise liked to turn up their noses at those with non-magical parents, the history of Hogwarts proves one thing: talent doesn’t care about your family tree.
From tragic heroes to “the brightest witch of her age,” these Muggle-borns proved they were just as powerful—if not more so—than any ancient wizarding dynasty.
. Justin Finch-Fletchley
Remember the Hufflepuff who almost went to Eton? Justin (played by Edward Randell) chose wands over waistcoats. While he was famously petrified by a Basilisk in Chamber of Secrets, his spot in Dumbledore’s Army showed he had the heart of a lion—even if he wore yellow and black.
. Dennis Creevey
The younger brother of Colin, Dennis was one of the youngest students to join Harry’s secret defense club. Coming from a family of “Muggles” that produced two wizards is a rarity, suggesting there was some serious latent magic in the Creevey genes.
. Colin Creevey
The boy with the camera! Colin (Hugh Mitchell) might have started as Harry’s fan, but he ended as a hero. Despite being expelled by Death Eaters due to his blood status, he sneaked back into the Battle of Hogwarts to fight for what was right, tragically losing his life in the process.
. Mary Elizabeth Cattermole
In one of the most tense moments of Deathly Hallows: Part , Mary (Kate Fleetwood) stood trial against the cruel Dolores Umbridge. While she needed a hand from Harry, Ron, and Hermione to escape the Ministry, her resilience in the face of the Muggle-Born Registration Commission made her a symbol of survival.
. Dirk Cresswell
You don’t become Head of the Goblin Liaison Office without some serious chops. Dirk (Ricky Wilson) was a favorite of Horace Slughorn and was so gifted he even managed to forge a fake family tree to try and evade the Death Eaters.
. Myrtle Warren
Better known as “Moaning Myrtle,” this Ravenclaw student (Shirley Henderson) had her life cut short by Tom Riddle. However, in death, she became a powerhouse of information, helping Harry solve the mystery of the Chamber and navigate the Triwizard Tournament.
. Edward “Ted” Tonks
The Black family was notorious for their “Always Pure” motto, but Ted Tonks was so charming he won the heart of Andromeda Black anyway. Though he stayed under the radar, his bravery in refusing to register with Voldemort’s regime showed a strength of character that clearly passed down to his daughter, Nymphadora.
. Kendra Dumbledore
It takes a formidable woman to raise Albus Dumbledore. Kendra kept her family together during their darkest years in Godric’s Hollow. While she tragically died in an accidental magical explosion caused by her daughter Ariana, her influence on the greatest wizard of all time cannot be understated.
. Lily Potter
“You have your mother’s eyes.” Lily (Geraldine Somerville) wasn’t just a “gifted” student and Head Girl; she performed the ultimate magic. Her sacrifice created a protection so deep and ancient that Voldemort couldn’t touch Harry for over a decade. Talk about girl power!
. Hermione Granger
Was there ever any doubt? Hermione (Emma Watson) redefined what it meant to be a witch. From brewing Polyjuice Potion in a bathroom to keeping Harry and Ron alive for seven years, she was the backbone of the revolution. As the “brightest witch of her age,” she proved once and for all that it’s not where you come from—it’s how much time you spend in the library!
