Summary: I guess you've had enough of viruses and pandemics but imagine this: The Wizarding World is often protrayed as quite backward; thus vaccinations were only introduced (as a concept) after Grindelwald's defeat, and many older people (especially lawmakers in the Wizengamot) are against vaccinations as a concept (perhaps due to prejudice against Muggles). Then, an epidemic or a pandemic of a disease breaks out that people could have been vaccinated against, but the vaccine lost its efficacy due to spread in the population and mutations. How does Hogwarts react to this? Or look wider, if you wish.

Summary: Before students are accepted to Hogwarts they must be assessed by a teacher or Ministry Official for academic proficiency. Professor Snape is assigned Harry Potter.

Summary: Severus is Harry's father, but when Lily died (perhaps when Harry was a bit older than he was in canon, so he slightly knows what's going on), he was devastated and turned to the drink, which led to him not being able to take care of Harry, little Harry, of course, wants to stay with his father but after Severus comes to the conclusion that he may end up hurting Harry since he can't control himself, he decides to up and leave, without anyone knowing where he went to, leaving Harry to the care of the Dursleys (whether he knows it or not is unimportant) ... skip to years later and Harry is about to start Hogwarts having grown up knowing his father had left him, but now guess who's back to be his teacher? - The reason Snape spent so long away is up to you, perhaps he was forced to leave to begin with, or he went to stay away for a bit but then couldn't return? -Snape does want to get close to Harry again and he is remorseful but perhaps not so good at showing it (maybe have him send Harry birthday cards while he was away so he wasn't completely out of touch- again it's up to you), Harry is just hurting because Snape left him to the abuse of the Dursleys - Bonus if Snape has made family or met someone while away which makes it even harder for Harry to forgive his father basically adds more angst... - Bonus for Happy endings... I like angst but please give it a good ending!

Summary: After the war, Harry offered to help to rebuild Hogwarts, during which he chose to talk to the portraits of Dumbledore and Snape about it.

Summary: Harry Potter gets fed up with being demonized, both in person by the Dursleys and the kids at school as well as in ink by Skeeter and her ilk. So he creates an anonymous editorial; you can have him print it in the Daily Prophet if you want (as long as its somewhere that it gets loads of attention). The thing is, this new writer has such a scathing tongue that even Severus Snape likes to read his new posts every morning at breakfast. This new writer is calling out everyone -- from Fudge and his cowardice to Dumbledore and his manipulations. And every morning at breakfast in the Great Hall, a pair of green eyes gleefully take in the reactions to his written take downs. Maybe Harry Potter cant stand up for himself in person by telling the wizarding world how ridiculous it is, but (insert pen name) certainly can.
