Amongst true fans of the Harry Potter franchise, fan theories abound related to main characters like Harry, Dumbledore, Hermoine, and Snape. However, some of the most interesting fan theories out there come from a less talked about group - the Marauders. Composed of James Potter, Remus Lupin, Sirius Black, and Peter Pettigrew, the Marauders of Hogwarts created the pivotally important Marauder's Map, which was essential to the plot of Harry Potter and the Prisoner of Azkaban. In these theories, we learn how it's possible that Peter Pettigrew was able to stay off the Map, why James Potter had such a troubled relationship with Snape, who actually created the Marauder's Map, and so much more. Whether you're a Harry Potter fanatic or a theorist yourself, these Marauders fan theories are a fantastical must-read.
James Potter And Snape's Mutual Resentment
From Redditor /u/Obversa:
Severus Snape resented James Potter, not just because he married Lily, but because James was everything he wanted to be. James, in turn, resented Snape for his closeness to Lily.514131Up to no good?
The Map Has A 'Hide The Marauders' Function
From Redditor /u/potter365:
It has ALWAYS bothered me that there is no clear explanation for how Fred, George, and Harry could have possibly overlooked the fact that Peter Pettigrew literally slept with Ron every single night and only Lupin catches it much later. Searching message boards I finally found an answer that helps me sleep at night.
This is provided by BolteAltamont:
'This is purely conjecture, but it's entirely possible that the Marauders placed some extra protection on the Map in case it were to fall into the wrong hands - a "hide-the-Marauders" function, if you will. If you think about it, this makes sense - for, as we know, it did fall into the wrong hands, and they wouldn't want anyone to know about their monthly excursions or any of their other Invisibility Cloak adventures. Moreover, they probably only would have wanted it to be a temporary function, so that they might be able to find each other if necessary.
So let's say that there was this hide-the-Marauders function, and it was enabled when Filch confiscated it. Fast forward to Fred and George discovering it. They don't notice anything wrong with it, of course, because none of the Marauders are supposed to be at Hogwarts... until the year in which Lupin arrives. Still, it's clear they don't use the Map much anymore by this point - they've outgrown it, and they're even passing it on to Harry. Nobody notices that the new Defense Against the Dark Arts teacher is never on the Map - and why would they? Both Harry and the Weasley twins probably like Lupin, so he's not somebody they'd be watching out for; plus, it's probably a lot harder to notice someone's absence from the Map than someone's presence on it (especially, regarding the case in point, if that someone shares a common room with you).
Then Lupin confiscates the Map, and what does he do with it? He's smart - he uses it to watch out for Harry, as we know he did on the day of Buckbeak's execution; he must also want to use it to watch out for Sirius Black, who has already managed to break into Hogwarts once. So he disables the hide-the-Marauders function, but by now Pettigrew (as Scabbers) is hiding out at Hagrid's out of fear, and no longer living in the Gryffindor Common Room. Because Lupin isn't focusing on Hagrid's hut - why would he? - he doesn't notice his old school friend until one night, when Harry, Ron, and Hermione sneak out to see Hagrid...
Again, based purely on conjecture and circumstantial evidence, but that's how I've always justified it in my mind.'624184Up to no good?
James Potter's Parents Died Of Dragon Pox
From Redditor /u/Obversa:
This theory was based on previous J.K. Rowling interviews, Pottermore, and the books:
Q: What about Harry's family - his grandparents - were they killed?
J.K. Rowling: No. This takes us into more mundane territory. As a writer, it was more interesting, plot-wise, if Harry was completely alone. So I rather ruthlessly disposed of his entire family apart from Aunt Petunia. I mean, James and Lily are massively important to the plot, of course, but the grandparents? No. And, because I do like my backstory: Petunia and Lily's parents, normal Muggle death. James's parents were elderly, were getting on a little when he was born, which explains the only child, very pampered, had-him-late-in-life-so-he's-an-extra-treasure, as often happens, I think. They [James's parents] were old in wizarding terms, and they died. They succumbed to a wizarding illness. That's as far as it goes. There's nothing serious or sinister about those deaths. I just needed them out of the way, so I killed them. (Source)
'Sir, I think you knew my grandfather, Abraxas Malfoy?' Harry looked up; Slughorn was just passing the Slytherin table. 'Yes,' said Slughorn, without looking at Malfoy, 'I was sorry to hear he had died, although of course it wasn't unexpected, dragon pox at his age...' - Harry Potter and the Half-Blood Prince, Ch. 9
Elderly patients are apparently more susceptible to dragon pox than younger ones. Eldritch Diggory died of it in 1747, as did Abraxas Malfoy, as recently as the second half of the 20th century. (HP Wiki, cited from Pottermore)
/u/Obversa, six days ago:
As Draco Malfoy's grandfather, Abraxas, died of dragon pox, I'm guessing that James's parents also died from it as well. (Source)
J.K. Rowling, today:
Fleamont and Euphemia lived long enough to see James marry a Muggle-born girl called Lily Evans, but not to meet their grandson, Harry. Dragon pox carried them off within days of each other, due to their advanced age, and James Potter then inherited Ignotus Peverell’s Invisibility Cloak. (Source)24437Up to no good?
James Potter Was Just A Bully
The fandom has had a difficult time deciding on how they feel about James Potter. I believe that this is because he never gets the chance to tell, or rather show, us who he is. We only learn about him through the words and memories of others and all of these things are skewed based on that individual's feelings towards him. Snape casts him as the villain because, to him, that is what he was. Meanwhile, his friends sing his praises. Rowling has explained that he was a git in his youth but grew into the man that Harry always thought he was.27854Up to no good?
