A Encanto & Jimmy Neutron Boy Genius crossover.
When Mirabel's door vanished on her gift ceremony, Alma asked her son Bruno to look into the future to see why. But the vision he had didn't show Mirabel in front of a cracked Casita. Instead, what it showed was A very different person - a boy with a big head, giant flying chickens, and monsters shaped like floating eggs, all of which he knows are NOT in the Encanto.

Will Mirabel see she's special as her family?
Will Jimmy understand how much family means to him and his friends?
And will they all learn important lessons along the way about family bonds that should never be torn apart?
You'll just have to read to find out!

Summary
Shockwave brings Megatron a theory so extreme it borders on heresy: that sparks can be forced into compatibility, and that a single Cybertronian can sustain multiple sparkbonds. If proven true, it could give the Decepticon cause an endless army born not of forges, but of nature bent to their will.
Megatron grants his scientist free rein. The test subjects? His Second-in-Command and the Decepticons’ most formidable soldiers. What follows is a cold, calculated descent into controlled chaos — where bonds are forged not through choice, but through design. The line between science and violation blurs, and the results threaten to unravel far more than Shockwave anticipated.

Summary
Alex traces the space from his groin to his navel in one last, languid movement of her tongue, then lies on top of him as if that was her place — her thighs loosely intertwined with his hips, the intense scent of their orgasms in the air.
He looks at her, and Alex greets him with a slender, satisfied profile; she rests her chin on his chest, just above his heart, smiling shamelessly.
"A penny for your thoughts, Al?" she asks, tapping her index finger in time with his heartbeat.
Wesker spares her a sidelong glance, lingering on the bright pink of her lips — reminding them around his cock, so soft and now stained with his seed.Series

Fraerling-sized, battle-worn, and carrying secrets no one believes, she becomes both a puzzle and a wonder—forcing [Strategists], students, and even the great Niers Astoragon to confront truths beyond their understanding.
Spoilers up to 10.38 E. I deliberately omitted some characters and changed some of the original plot.

Summary
"𝙏𝙝𝙚𝙧𝙚 𝙞𝙨 𝙣𝙤 𝙥𝙖𝙨𝙩, 𝙣𝙤 𝙛𝙪𝙩𝙪𝙧𝙚, 𝙩𝙝𝙚𝙧𝙚 𝙞𝙨 𝙤𝙣𝙡𝙮 𝙣𝙤𝙬"
It can be challenging to get used to the behaviour of the people in this era but it's important to remember that they are just trying to survive in their own unique way.
You never know what they're going through, and a little kindness goes a long way. Time travelling can be quite an experience. Therefore, keep an open mind and embrace the possibility of learning something new. With the right attitude and determination, one can navigate through these challenges and make the most out of this time travelling adventure.
But he doesn't seem to understand the gravity of the situation. He may be an arcanist, or perhaps something else entirely. However, the disregard for the seriousness of time travel can have devastating consequences. Every decision he made is like the butterfly's effect where a single flap can cause the Storm on the other side of the world. So beware, for he may be your saving grace... or the undoing of this universe as you know it.
