Summary
After years of experimenting with your ability to manipulate space- specifically teleportation- you decide it's finally time to test whether you also possess the power to travel through time. The motivation is clear and urgent: escaping a dark era where the Viltrumites rule over Earth.
You activate your powers and suddenly find yourself in an unfamiliar present. Within minutes, the Global Defense Agency locates you, having detected the disruption caused by your arrival.
One question echoes in your mind: did you end up in the right place at the right time?

Summary
Cassie Kent has been a superhero for two years—long enough to know a cape doesn’t make life simpler. Chicago is loud, chaotic, always on the brink, and she spends most days airborne putting out fires. She works alone, avoiding teams, politics, and especially the Guardians of the Globe. Their polished pitches can’t shake her instinct that something’s wrong. Trust gets people hurt.
Off-duty, she’s painfully normal. She lives with her cousin Clark, goes to school, keeps her head down. Sharp‑tongued and stubborn, she doesn’t try to impress anyone—least of all her annoying neighbor Mark Grayson, who insists they’re friends. She expects to forget him after graduation.
Then Mark reveals he has powers.
One confession cracks her walls. Suddenly he’s not just a weird kid—he’s dangerous, unpredictable, tied to something bigger. Cassie is pulled into uncovering the truth about his father, facing the possibility that one of the world’s greatest heroes is its biggest threat, and realizing she can’t stay on the sidelines anymore.

Summary
It left his words quick and easy. He meant it. He wanted to kill his father. He wanted to be the one to rip apart the white and red suit as he tore his father apart limb from limb. Mark has never had these thoughts before, but yesterday had changed him.
“Will I be trained?”
“Yes.”
Cecil saw no point in lying anymore.
“Will you train me?”
“Yes, and many others.”
The ten year old stood up, looking at Cecil with dark, grieving eyes.
“Then train me.”
If his father wanted a Viltrumite soldier, then he will become a soldier.

Summary
He could have ended it ages ago, snapped Rex’s spine like a twig, and walked away without a second thought. But he didn’t. Rex was a spark in the void, a rare creature that refused to break, always laughing, always defiant. So alive, it made Mark’s teeth ache. On a planet where everything else was dead or dying, Rex still burned.
OR
Mark fantasizes about Rex and using a unlikely hole :)

Summary
Kousei knows that all is lost. Kaori's surgery was never guaranteed to work. Still, he heads straight to Totsuhara University Hospital after the Eastern Japan Piano Competition is done. He needs to hear the news himself and get some closure.
But when he arrives, things do not go as he expected. Kaori is there, alive and whole! Standing! Kousei is overjoyed that the girl he loves is alive. He and Kaori share a tender embrace, so glad to be together again.
But a singular question nags at the back of Kousei's mind. How is this even possible? Surely it could just be a strange, one in a million miracle. Right?
As Kaori's father, Omni Man, looks upon their romantic reunion, he smiles in triumph. His daughter's Viltrumite blood was awakened by the poking and prodding of the surgeons. And now, he has someone to help him bring Earth into the Viltrum Empire.
The love that Kousei has for Kaori will be tested past its breaking point as Kaori's life takes a dark turn...that will alter the fate of the world.
