Summary
Petunia berated Harry Potter for being a freak, just like his mother. So when an incredibly tall fellow freak turned up to take him away, he was more than happy to go with them into a world of magic and mayhem.
Much to Dumbledore’s dismay, the tall freak in question wasn’t Hagrid, but Nora Bloodgood, the Headless Headmistress of Monster High. And when all Dumbledore’s efforts to find and rescue the missing saviour fail, he throws caution to the wind and throws Harry’s name in the Goblet of Fire.
The bigoted world of Wizarding Britain is not ready for a saviour raised by “creatures”.
A Monster High/Harry Potter Crossover!

Summary
After a failed first time with Harry, Draco is ready to run away and pretend it never happened, but the omega is not willing to let something so small ruin their budding relationship.
"Can we just... Can I try something?" Harry asks, his voice almost desperate as a wild idea comes to him.
Draco's expression is pained, but he takes a deep breath before speaking, and putting all his trust on Harry, the alpha asks. "What did you have in mind?"

Bookmarker's Notes
Harry spends his time rebuilding Hogwarts and the Wizarding World alongside Hermione, while dealing with severe PTSD. His post-war routine is interrupted by the arrival of the Lockhart-esque Potters from an alternate universe and their scapegoat younger daughter, Iris.
Some angst in earlier chapters. Fluffy friends to lovers Harmony feels. Iris is a precious cinnamon roll and Harry will make sure she knows it. The fake Potters are awful, manipulative, and vacuous people, but thankfully Harry has support and dances around their various schemes.

Bookmarker's Notes
Unwittingly opening the Lament Configuration frees Harry from the Dursleys, but the spectre of true fear hangs over Harry for the rest of his life in the form of a sinister melody. When Voldemort resurrects himself, Harry finally realises why he was allowed to live all those years ago…
Dark, violent, and gory. Harry makes some cruel choices to defeat Voldemort.

Oneshot.
Dudley gets a Nerve System to play SAO. The Dursleys get a spare set so they can send Harry to communicate with Dudley while he’s playing. Both of them get trapped in SAO. This changed everything. -

Ch 29
[Author has stated this is now abandoned pending a complete rewrite]
A fun take on MoD Harry being called in by Billy to help with Bella’s leech addiction, that spirals into hidden creature inheritances, mate bonds, found family, and mysteries.
Jasper is a simp, Harry is a more reserved simp, Bella is delightful as with support she finally outgrows the toxic relationship she was stuck in, Billy and Jacob adopt Harry immediately, and Rosalie adopts Riley.
