Pranksters or Pranked? by awitchnamedlou for rxgulus

Summary
Regulus Black had been having a good year. He'd managed to get out of going home for the holidays, prepping for OWLs was going well, he hadn't fought with Sirius (he hadn't seen Sirius), and he, Evan, and Barty had successfully undergone the animagus transformation. Sure, he still had to successfully carry out the whole running away thing, but that was future Regulus's problem.
Everything was monotomous and predictable, just how he liked it.
At least it was, until Barty had an idea.
What if they got back at the so-called 'marauders' for all the grief they'd given the Slytherins over the years? And with their animagus forms, it's not like they'd be seen or caught...
What could possibly go wrong?
We do not support JKR in this house

Summary
James Potter takes some much needed time for himself for the first time in his 17 years of life. Instead of thinking deep thoughts and finding inner peace like he’s supposed to be doing, he finds a cat.
The cat, of course, is not just any cat and isn’t even that good at pretending like it is.
Meanwhile, Regulus Black’s sixth year is more stressful than anyone’s sixth year has any right to be and not just because he’s assigned himself the part time hobby of single-handedly taking down this generation’s great evil.

Summary
After Peter and Regulus destoyed one horcrux, they find themselfes with new challenges. Like what it means to be free, after 13 years in prison, how to stand against old friends, or how to steal from children.
... Well Regulus has no problem with the last one. He would do it again.
---
Realistically speaking, neither Peter nor Regulus were made of the material to stand against the former Dark Lord, even if he was currently nothing but a shade.
They weren’t geniuses like Siri or Potter (the older); they weren’t particularly brave either, not to mention their dubious moral integrity.
He hadn’t feared the Dark Lord when he had walked into that cave, nor when he was imprisoned by the man. But he had wanted to die back then. And now, with his newfound purpose in life... he wanted to survive. And so maybe it was only natural that he feared what was to come.Series

But Regulus has never been the best at making choices.

Trapped in his Animagus form, silent and scarred, he lived in the forgotten corners of the world, until one day he gets badly injured and seeks the only support he can think off.

Summary
This is it. The last night Sirius will ever be in the cold, dark, loveless tomb that is 12 Grimauld Place.
Except, it isn't entirely loveless, is it? No, Sirius remembers his baby brother and all the love they've shared, all the little laughter and tiny moments of light they've brought to these haunted halls.
The thought of his baby brother has Sirius pausing, bag halfway lifted to his shoulder.
Sweet little Regulus. The reason he hasn't left thus far. But no, the boy will be okay. He's always been less outspoken, more willing to take the path of least resistance, keeping his head down.
Regulus will be fine in this house. He will be safe. But it couldn't hurt to check on him one last time. The boy is probably already asleep anyway. There's no risk of him realising there's something off—no risk of Regulus trying to stop him
OR What if the night Sirius plans to run away, he goes to check on Regulus one last time, only to find a tiny black kitten where his brother should be?
