Although an original member of the Order of the Phoenix, petty criminal Mundungus Fletcher was not particularly known for his magic or his courage. That said, his illicit connections helped provide valuable information to the Order. However, his cowardice got him into trouble on more than one occasion, when he abandoned his guard post at the Dursley home, earning him a reprimand from Arabella Figg. Later, Fletcher agreed to pose as one of Harry’s doubles during the Battle of the Seven Potters; but when he and Alastor Moody were attacked by Voldemort, Fletcher immediately fled, resulting in Moody’s death at Voldemort’s hands.
Mafalda Hopkirk played an integral role in Harry’s infiltration of the Ministry, but not because of her magical abilities. As an assistant in the Improper Use of Magic office, she was known for her spoken word and self-destructive cards that chewed up rule breakers, but not much else. Even the Death Eaters considered Hopkirk inconsequential; after Voldemort’s followers took over the Ministry, she was left largely alone.
While other non-dark witches and wizards were killed, imprisoned, or forced to flee, Hopkirk was kept by the new management and used as a gofer and stenographer for Dolores Umbridge. Hermione would later easily stun Hopkirk, using some of his hair to brew a Polyjuice potion and posing as Mafalda to steal Salazar Slytherin’s locket from Umbridge.
While he could definitely speak of a great game, Gilderoy Lockhart’s empty boasts led to his eventual downfall. Lockhart was a smart and promising student, enough for the Sorting Hat to place him in Ravenclaw.
Unfortunately, he was impossibly vain from a young age. Full of ambition, Lockhart lacked the drive or tolerance for personal failure. Memory charms became his sole focus after graduation, a spell he became quite adept at. This allowed her to erase the memories of talented witches and wizards around the world, taking credit for his exploits in the many books he wrote. Dumbledore made Lockhart a professor again in hopes of stopping him, a plan that came to fruition when the Chamber of Secrets was opened and Lockhart ended up accidentally erasing his own memory of him.
He may not remember Stanley Shunpike, which is understandable. Shunpike was an unimportant wizard with little talent, which is why he ended up being the driver of the Knight Bus. He wasn’t the sharpest knife in the drawer, which was evident when Harry tricked him by posing as Neville Longbottom.
Like Gilderoy Lockhart, Shunpike had an annoying streak of self-aggrandizing vanity; he later falsely bragged to his friends that he had information about the Comefa de la Muerte’s plans. He got more than he bargained for when his lies landed him in Azkaban. During the 1997 breakout, Shunpike was forced to join the Death Eaters when they put him under the Empire’s curse. He was later easily disarmed by Harry Potter during the Battle of the Seven Potters. His fate after Voldemort’s death remains unknown.
Scabior was another wizard with a bad reputation, even spending time in Azkaban for unknown crimes. After his release and the compromised Ministry began their violent campaign against Muggles and others, Scabior joined his efforts as Thief.
Although he was responsible for catching many fleeing witches and wizards, it should be noted that he did not do it alone. The Thieves of Scabior group was led by the werewolf Fenrir Greyback. At Malfoy Manor, he was easily stunned by Bellatrix Lestrange before she could pull her wand out of her. He later met the end of him at the hands of Neville Longbottom, who dueled him briefly at the Battle of Hogwarts. Longbottom led Scabior and other Snatchers to the covered bridge, sending them to their deaths when Seamus Finnegan’s charges caused the bridge to collapse.
Crabbe the Elder
The father of Draco Malfoy’s lackey, Vincent Crabbe, Mr. Crabbe was a dead-eater for Voldemort. Like Lucius Malfoy, Crabbe managed to escape punishment for his role as Comemorios during the First Wizarding War, likely by claiming that he had been an Imperious. He rejoined Voldemort upon his return and was then sent to fight members of Dumbledore’s army in the Department of Mysteries. In the Time Chamber, Harry Potter easily incapacitated Crabbe with an amazing spell. He was later sent to Azkaban, but later escaped and participated in the Battle of Hogwarts, but it is unknown if he survived.
He may have the name Lestrange, but Rastaban doesn’t have anywhere near the skill of his brother, Rodolphus, or his famous sister-in-law, Bellatrix. Like them, Rastaban was a devoted follower of Voldemort, and was later imprisoned in Azkaban along with them. After they escaped from Azkaban, he returned to his Death Eater position, and was present at the skirmish in the Department of Mysteries. Along with Mr. Crabbe, he chased Harry and the others into the Time Chamber. Like Crabbe, he didn’t last long. Neville Longbottom disarmed him and Hermione stunned him before he could retrieve the wand from him. Following a second escape, Lestrange was at the Battle of Hogwarts, but his ultimate fate remains unknown.
Along with many other witches and wizards who believed in Voldemort’s pure-blood ideology, Travers became one of his Death Eaters during the First Wizarding War. It is said that he personally murdered the entire family of Order of the Phoenix member Marlene McKinnon. He escaped from Azkaban along with Bellatrix Lestrange, and soon rejoined Voldemort. At the Department of Mysteries, he held Ginny Weasley hostage for a short time, but was quickly incapacitated by a member of the Order and sent back to Azkaban. Unfortunately, the Ministry was taken over by Death Eaters only a few days later, and Travers was “cleared” of his crimes.
He was later seen at the Battle of the Seven Potters, where Kingsley Shacklebolt defeated him with a curse. Later, Harry and his friends easily escaped Travers and another Death Eater when they arrived at Xenophilius Lovegood’s house. When they carried out their Gringotts Bank robbery, Harry was able to use the Imperial Curse on Travers to help them disguise themselves. Travers later fought in the Battle of Hogwarts, but was presumably defeated by Dean Thomas and Parvati Patil.
A notorious eccentric, Xenophilius Lovegood was the publisher and writer of The Quibbler magazine and the father of Luna Lovegood. He was apparently an expert in all manner of esoteric and dark deeds, but was never shown performing any powerful magic.
While many of his beliefs were quite ridiculous, Lovegood’s encyclopedic knowledge proved valuable when he informed Harry, Ron, and Hermione about the nature of the Deathly Hallows. His support of Potter in The Quibbler caused the Death Eaters to kidnap his daughter and Lovegood was forced to betray Harry. He summoned the Death Eaters and tried to stun Harry, but missed and hit an Erumpent horn, which blew up his house. He survived, but the Death Eaters sent him to Azkaban for failing to capture Harry, where he remained until the end of the war.
Although he was intelligent and free, Quirinus Quirrell was the weakest of the Hogwarts teachers, mostly due to his extremely timid nature. He taught the muggle studies course for several years before going in search of the vanquished Voldemort. He no doubt thought that finding the Dark Lord’s remains might earn him some respect in the wizarding world, but he got much more than he bargained for. Quirrell was successful in finding Voldemort, who quickly took possession of his body, taking up residence in the back of Quirrell’s head. Later, the professor would try (and fail) to steal the Philosopher’s Stone, but even with Voldemort’s strength helping him, he was killed.
