An Animagus is a witch or wizard who can transform themselves into an animal and back again at will. This ability is achieved by studying and practicing exceptionally advanced Transfiguration. Becoming an Animagus is an extremely difficult and dangerous process, which is closely monitored and controlled by the Ministry of Magic. There are very few registered Animagi, as the process of becoming one is long and arduous, with many witches and wizards not possessing the skill, patience, or discipline to achieve it.
In the Harry Potter universe, there are only seven known registered Animagi. They are:
- Minerva McGonagall
- James Potter
- Sirius Black
- Peter Pettigrew
- Rita Skeeter
- Horace Slughorn
- Falco Aesalon
In this article, we will explore who these seven witches and wizards are, what animal forms they can take, and how they achieved the rare accomplishment of becoming registered Animagi.
Minerva McGonagall
Professor Minerva McGonagall is perhaps the most well-known Animagus in the Harry Potter stories. She serves as Transfiguration professor and Head of Gryffindor House at Hogwarts School of Witchcraft and Wizardry. As a registered Animagus, Professor McGonagall can transform into a silver tabby cat with distinctive markings around her eyes.
McGonagall often uses her Animagus ability to secretly observe events and situations. She will transform into her cat form to prowl around unnoticed. This allows her to keep an eye on the school and her students when necessary. She first demonstrates this unique talent in the first Harry Potter book, surreptitiously spying on the Dursley family in the days before Harry’s 11th birthday.
As a teacher, Professor McGonagall emphasizes the dangers and difficulties of human transfiguration. She cautions her students that any mishaps with these advanced magics can have permanent consequences. Despite these warnings, she recognizes Hermione Granger’s extraordinary talent and maturity in Transfiguration. In their sixth year, McGonagall helps guide Hermione through the process of becoming an Animagus, though Hermione ultimately decides not to officially register.
McGonagall is precise in her magic and maintains strict control over her transformations. She exhibits the mastery of Transfiguration that is required to successfully and safely become an Animagus. Her accomplishment is a testament to her magical skill, determination, and respect for the laws of the wizarding world.

- Occupation – Hogwarts Transfiguration professor and Head of Gryffindor House
- House – Gryffindor
James Potter
James Potter, father of the famous Harry Potter, was one of the Marauders who attended Hogwarts and mastered becoming an Animagus in his fifth year to assist his friend Remus Lupin. James could transform into a tall red stag at will. Along with fellow Marauders Sirius Black and Peter Pettigrew, they secretly learned the advanced magic to help Remus with his monthly werewolf transformations.
As a stag, James could keep Remus company during full moons and prevent him from attacking other humans. A werewolf is only a danger to people, not other animals. This allowed the four friends to explore the Hogwarts grounds and Hogsmeade village together during the full moon. James’ talent and loyalty to his friends led him to achieve the incredibly difficult Animagus transformation as just a teenager.
However, the Marauders did not officially register as Animagi with the Ministry of Magic during their school years. They kept it secret to continue discreetly accompanying Remus on his monthly escapes from the Shrieking Shack. James only registered later in life, after graduating from Hogwarts.
Key Facts
- Animal form – Tall red stag
- Occupation – Member of the original Order of the Phoenix
- House – Gryffindor
Sirius Black
James Potter’s best friend Sirius Black also became an unregistered Animagus in his fifth year at Hogwarts. He could transform into a large black dog. Along with James and Peter Pettigrew, Sirius joined in the dangerous process of becoming an Animagus to support their friend Remus Lupin.
With his shaggy black dog form, Sirius provided extra protection and companionship for Remus during the full moons. As a dog, Sirius could restrain the werewolf if necessary and stop him from running loose or hurting himself. Sirius’ undertaking of such a difficult magical accomplishment at a young age shows his intelligence and loyalty to his friends.
Sirius only officially registered as an Animagus after he escaped from Azkaban prison in Harry Potter and the Prisoner of Azkaban. As an unregistered Animagus, Sirius was able to use his dog form to secretly escape the wizard prison and swim to the mainland. His illegal status allowed him to evade capture by the Ministry of Magic for so long.
Key Facts
- Animal form – Large black dog
- Occupation – Member of the original Order of the Phoenix
- House – Gryffindor
Peter Pettigrew
The least capable of the Marauders, Peter Pettigrew also managed to learn how to become an Animagus along with James Potter and Sirius Black. Peter’s Animagus form was a fat grey rat. This allowed him to access the Whomping Willow tunnel and immobilize the violent tree so the Marauders could join Remus Lupin during the full moon.
Though less talented than his friends, Peter was determined not to be left out of their secret missions. By mastering the Animagus skill along with James and Sirius, he could remain part of their daring adventures. However, his motivations tended to be more self-serving than the loyal Sirius and James.
Like his fellow Marauders, Peter did not register his abilities until later in life, long after leaving Hogwarts. He used his unregistered status to fake his own death and frame Sirius for betraying James and Lily Potter. Peter cut off his own finger, transformed into a rat, and disappeared into the sewers with the other rats. For 12 years he hid in his Animagus form as a pet rat with the Weasley family, known as Scabbers.
Key Facts
- Animal form – Fat grey rat
- Occupation – Member of the original Order of the Phoenix (secretly a spy for Voldemort)
- House – Gryffindor
Rita Skeeter
The notorious journalist Rita Skeeter is an unregistered Animagus who can transform into a beetle. She uses this ability to sneak around and eavesdrop on private conversations, aiding her reporting. As a beetle, Rita can hide easily and listen in on unsuspecting wizards and witches to gather material for her sensationalist articles.
During the Triwizard Tournament in Harry’s fourth year, Rita spies on the Hogwarts grounds in her insect form. She overhears discussions between Hagrid and Madame Maxime, and Harry and his friends. Rita then publishes stories using this ill-gotten information despite having no permission or verification of the facts.
After Harry discovers her illegal Animagus ability, he blackmails Rita into not writing for one year. This forces Rita to finally register herself as an Animagus with the Ministry to avoid being punished for breaking wizarding law. She continues writing salacious stories, but cannot use her unregistered Animagus status to sneak around going forward.
Key Facts
- Animal form – Beetle
- Occupation – Reporter for the Daily Prophet
Horace Slughorn
Professor Horace Slughorn also was revealed to be an Animagus skilled enough to be registered by the Ministry of Magic. Slughorn’s animal form is an armchair, which he transfigures himself into to camouflage and hide from Death Eaters when they attack Hogwarts in Harry Potter and the Half-Blood Prince.
Slughorn was described by J.K. Rowling as an accomplished wizard who liked to cultivate famous connections. As such, he likely wanted to master the notoriously difficult Animagus transformation to impress others and prove his abilities. Becoming legally registered would add legitimacy.
Though less detail is known about Slughorn’s specific Animagus skills, he did put it to good use hiding from dangerous dark wizards by transfiguring into a mundane piece of furniture. This shows his quick thinking and mastery of human transfiguration.
Key Facts
- Animal form – Armchair
- Occupation – Hogwarts Potions Master and Head of Slytherin House
Falco Aesalon
The final registered Animagus is a wizard named Falco Aesalon. Very little is known about Aesalon, as he is only briefly mentioned on the official Wizarding World website. His name appears on the Animagus Registry that tracks all registered Animagi in the Ministry records.
From his name, we can surmise that Falco Aesalon’s Animagus form is likely a falcon. The name may be a play on the Latin words for falcon (falco) and hawk (astur). This is speculation, however, as details on Aesalon’s abilities and backstory have not been revealed.
The registry shows that Aesalon was added to the list sometime in the late 19th or early 20th century. As a registered Animagus, he must have successfully demonstrated the skill to Ministry officials before being added to their records. Beyond this, not much is known about this mysterious wizard who mastered one of the most difficult branches of magic.
Key Facts
- Animal form – Likely a falcon (unconfirmed)
- Occupation – Unknown
- Lived in the late 19th or early 20th century
The Difficult Journey to Becoming an Animagus
Based on the seven known registered Animagi, the path to achieving this magical ability is extremely challenging and dangerous. J.K. Rowling emphasized that only very advanced witches and wizards could become Animagi, under close Ministry supervision.
The process involved studying obscure Transfiguration texts and practicing extensively. The wizard had to precisely visualize and focus their intent on the animal form they wanted to assume. If any details were visualized incorrectly or the magic poorly executed, the wizard could end up permanently stuck halfway between animal and human form.
For example, Viktor Krum’s grandfather attempted to become an Animagus but failed to visualize his complete transformation. He ended up permanently disfigured with a shark’s head and had to live out his life in lonely seclusion.
In addition to the precise magic involved, becoming an Animagus required patience, discipline, and determination. The wizard had to meticulously practice the visualization and transformation skills over an extended period of time. J.K. Rowling noted that few people had the necessary skill and perseverance to succeed.
Steps to Become an Animagus:
- Study advanced Transfiguration texts on human transformation.
- Pick an animal form and meditate extensively on visualizing the full transformation.
- Practice transforming individual body parts into the animal’s equivalent.
- Work on transforming the entire body smoothly from human to animal and back again.
- Repeat steps 3-4 extensively until the visualization and transformation is precise.
- Register with the Ministry of Magic once transformation skill is proven consistent.
Given the intense study and practice required, it’s no wonder only seven wizards were registered with the Ministry by the 20th century. The Marauders were truly extraordinary to achieve this as teenagers, though they did so illegally. For most, it requires mastery of Transfiguration magic gained over many years of disciplined work and apprenticeship.
As a result, registered Animagi were extremely rare in the wizarding world. Their unique abilities garnered respect and renown among magical society. The seven known registered Animagi stand out due to their exceptional talents and dedication to mastering this pinnacle of Transfiguration.
Conclusion
Becoming a registered Animagus was an impressive and difficult accomplishment in the Harry Potter universe. The seven wizards who achieved this skill demonstrated remarkable talent, intelligence, perseverance, and mastery of magic. Their unique abilities inspired awe throughout the wizarding world.
Each brought different motivations and creative uses for their powers based on their diverse personalities and backgrounds. From Marauder adventures to evading Death Eaters, they used the privilege of becoming animal forms responsibly and for good causes. Their exceptional Transfiguration skills made them stand out as some of the most remarkable wizards of their time.
