Humans Make Monsters Look Like Amateurs by Catthhay

Summary
Nezu spends his life among humans, yes. He made a career out of training the best of them to save, to fight, to be good. Because Nezu has seen what humans can do when left alone to choose their own path. They murder. They torture. They experiment. He needs to make sure they are raised with proper morality, that the good traits are the ones nurtured. But part of him will never be able to fully let down his guard around any human ever again. Part of him will always burn for revenge.
When a random kid’s quirk awakening brings him a not-quite-human child with all the same scars he saw in the mirror, figuratively anyway, Nezu finds himself experiencing something brand new.
Paternal instincts.
—*—*—*—*—*
Listen, I love Dadzawa just as much as the next guy (and he’s still here, no worries!), but I feel like we are collectively missing an opportunity for Rat!Dad Nezu. He’s a (debatably) responsible adult, clearly (debatably) good with kids, and SOMEONE needs to bully him into quitting smoking. I volunteer Danny Fenton as tribute. -

Summary
I got bored because none of the stories for my current hyper-fixations are updating fast enough to meet my brain’s demand so I started a new hyper fixation and wrote it.
—————Skala understood things like joy and love in theory. They also understood that their brain simply was not capable of processing or feeling those sorts of emotions. Demons were simply not meant to know love. They were meant to fight, devour, and only respected strength.
So why was Skala always so jealous of the smiles humans wore so readily, of the spark in their eyes when they protected people they cared about, rather than their skill with a blade or the size of their aura?
Frieren, meanwhile, is absolutely certain this demon is hiding a malicious master plan of some sort. She will not make the same mistake so many others before her have— she just needs the right moment to kill it. Last week wasn’t the right opening. Or the previous week. Or that one time they had tea together. And it would have been disastrous to kill it when it was giving Fern a haircut.
She just needed to be patient and wait for the demon’s mask to slip.

Summary
Spider-Man. One of the most cryptic heroes out there, especially considering not even the Batfam has been able to figure out his identity. No, this has nothing to do with Peter Parker suddenly learning how to lie. Rather, someone else has always known how to string together a good Fib and has a lifetime of practice hiding secrets they want nobody else to know. Because, unbeknownst to everyone, there isn’t just one spider-man. There are two. And they tag out whenever they need to, to protect both their identities and each other.

Summary
I haven’t consistently written fanfiction in over a year, idk what’s wrong with me (lots of life changes and writer’s block) so I decided to make a bunch of drabbles for my latest hyperfixation as a way to get back in the swing of writing.
Enjoy a ton of absolutely unhinged Danny Fantom x Batfam one shots.

Maximalism by Catthhay

Summary
The name Roronoa was always meant to go down in history. In one timeline, what some people may consider the Original timeline— the “right” universe— there is only one Roronoa Zoro. The eventual World’s Greatest Swordsman.
In another universe, another sequence of events with the same general cast of characters, there is still only one Zoro— but he is not the only Roronoa left. Being raised by the hotheaded Zoro is sure to leave its marks, but this is not a story about two people aiming for the top of the world of swordplay.
This is not a carefree comedy. This is a story of spite, of freedom and prejudice and gene-deep strength. This is a story of a powerhouse that never should have been born. This is a story of rebellion.
This is the story of Roronoa Ziri and the Strawhat Pirates.

Summary
After escaping his parents' experiments when they discovered his identity as Phantom, Danny runs to the last place they'd expect him to hide--Crime Alley, Gotham City.
He never expected he'd somehow pick the one apartment next door to one of the Bats' and Birds' safehouse.
Now seemingly perpetually injured, homeless, and on his own, Danny suddenly finds himself surrounded by a family far more caring than what he's used to.
