Castor Lilypott, the Freak Who Lived by Portias_Nest
Fandoms: Harry Potter - J. K. Rowling, Monster High (Cartoon 2010)
03 Feb 2026

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! Updates every Tuesday!

One Less Day from Dying Young by Triscribe
Fandoms: The Old Guard (Movie 2020), Harry Potter - J. K. Rowling

Summary
They are the Old Guard.
They fight. They die. They get back up and keep fighting.
What are they supposed to do with a baby?
(I've got other AUs featuring "Harry raised by this or that family", "Harry 'stolen' and raised by muggle thieves", and "Harry (to be) raised by Batman", but I honestly don't think Hogwarts would be able to handle a "Harry raised by semi-immortal warriors, including a former soldier of Napoleon's army, two men who first met on opposite sides of the Crusades, and a woman who's been alive for over seven effing thousand years".
So of course, I *needed* to give it a shot. For Reasons, you understand.)

Are You Alice? by Philomela
Fandoms: Alice in Wonderland (2010), Harry Potter - J. K. Rowling

Summary
Was this some sort of punishment for running away from Ginny? Because that wasn’t really his fault. He had been set up to propose to her, in the gazebo, while all two hundred of their party guests watched on. Everyone knew that he did stupid things when put under pressure! So was it really his fault that when he had caught sight of a talking rabbit — in a waist coat, holding a pocket watch, and addressing him — he had taken off running after the creature?
“Are you sure about that?”
Apparently, yes, it was his fault.

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.
