While in school together, Sirius once tricked Snape into almost entering the Shrieking Shack while Lupin was there, transformed into a werewolf. James realised the danger and stopped Snape, saving his life; this is the incident Dumbledore referred to at the end of the first book.
In the backstory of the Harry Potter franchise, James Potter's rescue of Severus Snape served as a quietly pivotal moment in the world -- even if neither man was particularly happy about the development, and it only spurred on their longstanding rivalry.
James saved Snape from Sirius'' attempt to kill him. We see in Snape''s Worst Memory (Order of the Phoenix, “Snape's Worst Memory,” pp. 641-50) that there is very little love lost between Snape and the Marauders (particularly James).
Where did James Potter get the invisibility cloak from? The Invisibility Cloak originated from Ignotus Peverell, James' ascendant. The Cloak was passed from father to son, mother to daughter, through the centuries until James received the Cloak from his own father.
At the end of Philosopher's Stone, Dumbledore tells Harry that Snape was trying so hard to protect Harry because James once saved Snape's life.
In the sixth book, Dumbledore dies when facing Severus Snape on top of the Astronomy Tower, as Harry helplessly watches from concealment.
Harry Potter: Stag
Harry's patronus is undoubtedly the most recognizable. The stag is first seen in Harry Potter and the Prisoner of Azkaban when it saves Harry and Sirius Black (Gary Oldman) from the dementors at the lake.
"Linfred was a vague and absent-minded fellow whose Muggle neighbours often called upon his medicinal services," Rowling explained. It was these "medicinal services," including "Skele-gro" and "Pepper Potion," that were the beginnings of the Potter family fortune.
Albus Percival Wulfric Brian Dumbledore was the only wizard Voldemort ever feared and the only one who could have defeated him in a duel. Albus Dumbledore is the most powerful wizard in the Harry Potter.
Voldemort intentionally made six Horcruxes, but when he used Avada Kedavra on Harry, he unintentionally created a seventh Horcrux. Instead of dying, Lily's love for Harry created a counter 'curse' known as Sacrificial Protection and saved Harry.
In the final book, “Harry Potter and the Deathly Hallows,” Rowling reveals that Snape was acting on Dumbledore's orders and had protected Harry at school out of love for Harry's mother, Lily. “Snape died for Harry out of love for Lily,” Rowling said.
But, despite his maltreatment of Harry and the complicated killing of headmaster Dumbledore (who knew he was a double agent?), Snape did sacrifice his life for Harry at the Battle of Hogwarts.
A Professor at Hogwarts School of Witchcraft and Wizardry, Snape is hostile to Harry due to his resemblance to his father James Potter, who bullied Snape during their time together at Hogwarts. As the series progresses, Snape's character becomes more layered and enigmatic.
Voldemort trusts Snape because he's good at his job as a double spy and as an Occlumens. Voldemort is so conceited that he probably just doesn't expect Snape could be a better Occlumens than he is a Legilimens.
Harry feels devastated when he sees James bullying Snape in the Pensieve. He knows almost nothing about his parents until he starts Hogwarts. Then he begins to weave a mythology around them, with plenty of help from others.
Godrick Gryffindor, one of the four founders of Hogwarts, and the owner of the legendary Sword of Gryffindor, was absolutely more powerful than Dumbledore— and it's a good thing he was, too, because Dumbledore wasn't around in Hogwarts' early days to keep Godrick's fellow founder Salazar Slytherin in check.
Merlin himself was sorted into Slytherin when he was at Hogwarts, and the young wizard went on to become one of the most famous wizards in history. The Order of Merlin, named to commemorate him, has been awarded since the fifteenth century.
But even way back in Merlin's era, wizards were still a known quantity, so it's not like people had nothing to compare him to. As such, we're confident that Merlin's magical skills probably were greater than Dumbledore's own – although just how much greater is open for debate!
Both Lily and James Potter were killed by Voldemort aged 21 at Godric's Hollow on 31 October 1981, when Harry was just 1 year old, And the rest of the story, you no doubt know.
It's debatable whether the Malfoy family fortune is greater than the combined Potter and Black family fortune, but it's safe to say Harry individually has a greater amount of money than Draco.
Since we know one galleon is equal to around $25, the minimum amount of money in Harry's vault is a mind-blowing $1,265,625! And that's the baaaaaare minimum considering that in the books, although no specifics were given, A LOT more money was depicted.
1 Albatross
As the rarest Patronus in the Wizarding World possible, the Albatross represents an enormous bird that flies freely across any sea. This rare Patronus represents those who are simultaneously fearless, optimistic, happy-go-lucky, and ambitious.
Severus Snape is one of the most divisive characters in the entire "Harry Potter" series. He was a double agent, so many character details were kept a secret. His mother was a witch and his father was a Muggle, leading to the moniker "The Half-Blood Prince."
If Harry had been put in Slytherin, Snape, as the head of house would see him more and find more reasons to hate him and make his life miserable.
