You might be curious about how Pettigrew managed to keep his secret for such a long time. Well, being a rat let him sneak around and spy on both sides of the wizarding battle.

Pettigrew’s rat years show us that things aren’t always what they seem in the Wizarding World. His tale is a reminder to dig deeper and not just judge by appearances. Even the tiniest critters can shake things up in a big way.

The Life of Peter Pettigrew
Peter Pettigrew's journey was filled with important moments and relationships. From being a Hogwarts student to turning into an Animagus rat, his life really shaped his destiny in the wizarding realm.
Early Years and Hogwarts
You might be surprised to know that Peter started off as a regular wizard. He joined Hogwarts School of Witchcraft and Wizardry in 1971. The Sorting Hat put him in Gryffindor, a house known for bravery.
At Hogwarts, Pettigrew wasn’t the brightest of students. He often struggled and needed help from his pals. But despite that, he made some close friendships that turned out to be really important in his life.
Becoming an Animagus
While he was at Hogwarts, Pettigrew pulled off something impressive. He learned how to be an Animagus - that means being able to change into an animal whenever he wanted. His animal form? A rat, which is why everyone called him "Wormtail."
This ability was a huge deal for Pettigrew. It let him:
- Help his buddy Remus Lupin when he turned into a werewolf
- Sneak around and eavesdrop without anyone catching him
- Stay off the radar in the wizarding world for years
Association with the Marauders
Pettigrew's best mates at Hogwarts were James Potter, Sirius Black, and Remus Lupin, and they formed a close-knit group called the Marauders.
The Marauders were known for:
- Creating the Marauder's Map
- Playing pranks and breaking the rules
- Sticking by each other through good times and bad
Even in this group, Pettigrew often felt like he was in the shadows of his more talented friends. That feeling of being less than contributed to some poor choices that he made later.

The Betrayal and Aftermath
Peter Pettigrew's betrayal of the Potters changed everything in the wizarding world. What he did led to heartache and years of lies that affected so many people.
The First Wizarding War
During the First Wizarding War, there was chaos all around in the wizarding community. Voldemort and his Death Eaters were getting a lot of power, while the Order of the Phoenix fought back with people like James and Lily Potter leading the charge.
But Peter, once a loyal friend, chose to side with Voldemort. He made that choice out of fear and a need to feel safe. As things got tougher, everyone’s loyalties were challenged. Pettigrew's choice proved disastrous for those who once trusted him.
Secret-Keeper and Betrayal
When the Potters went into hiding with the Fidelius Charm, you might think Sirius Black was their Secret-Keeper. But nope, it was actually Peter Pettigrew. That switch sealed their doom.
Pettigrew ended up telling Voldemort where the Potters were hiding. His betrayal led to their deaths on October 31, 1981. It shook the wizarding world and left little Harry Potter an orphan.
Faked Death and Years in Hiding
After he betrayed them, you'd think Peter would get caught, but he actually faked his own death in a busy street. He framed Sirius Black for killing 12 Muggles and staged his own "death."
Then he transformed back into his Animagus form - a rat. For 12 years, he lived as "Scabbers," the Weasley family rat. This trick let him hide in plain sight without getting caught.
His rat years symbolized how cowardly he was. He’d rather live as a pet than face the fallout from his dark choices. This charade went on until things got spicy in Harry Potter's third year at Hogwarts when the truth finally came to light.
Reappearance and Final Acts
Pettigrew's comeback was a key moment in the wizarding world. His actions played a big part in Voldemort's return and everything that went down in the Second Wizarding War.
Identity Revealed
After years of being Ron's pet rat, Peter's real identity was uncovered at Hogwarts. You saw Sirius Black and Remus Lupin force him to change back into his human form.
This surprise shook Harry and his friends. It proved Sirius was innocent and showed everyone that Pettigrew was the real backstabber who betrayed Harry's folks.
He managed to escape that night by turning back into a rat and ran off to find his old leader, Voldemort.

Role in the Second Wizarding War
By now, wearing the name Wormtail, Pettigrew was critical to Voldemort's comeback. You probably noticed that he:
- Helped Voldemort whip up a temporary body
- Kidnapped Bertha Jorkins for info
- Aided in the ritual to help Voldemort regain his full form
As a reward for all this, Voldemort gifted Pettigrew a new silver hand. This magical hand replaced the one he lost during the resurrection ritual.
Wormtail kept serving the Dark Lord through the war, often doing grunt work for other Death Eaters.
Peter Pettigrew’s Fate
Pettigrew's end came during the Second Wizarding War. You likely remember his last run-in with Harry Potter at Malfoy Manor.
When Harry reminded him about the life debt he had, Wormtail hesitated to do any harm. That moment of mercy turned out to be a big mistake. The silver hand Voldemort gave him turned on him and strangled him to death.
This tragic ending highlighted the outcome of Pettigrew's choices and where his loyalties lay. That tiny moment of doubt about hurting Harry ultimately cost him his life, thanks to his own master's "gift."
