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
He lied about being a superhero. You lied about not having freaky ass mind powers. You broke up- bitterly. End of story. No shot Invincible and some superpowered grunt for Machine Head would ever work out in any reality. Except. When he comes in droves, hoards of himself, brokenhearted and wanting, wrecking cities for a chance to get one last glance at you.

Years after the events of Chicago (following the TV series), Mark Grayson changes occupation from a bright-faced hero to a grief-stricken homicide detective, hiding his powers and past. There is no room for anything in his heart anymore, not after what happened to him. But of course, that was before he met the beautiful college girl in a bar, only 3 stools away from him.

Summary
His breath ghosts your cheek as he leans in. "Easy," he teases, voice low. Your friends laugh again, blissfully unaware. "You're starting to really look like you wanna hit me."
You turn to him, lips pulling back into a grin that feels more like bared teeth. Your fingers curl around his forearm, nails pressing into his sweater until you feel his skin dent. He doesn't flinch, only chuckles softly, the sound barely audible.
"I do." You dig your nails deeper.
The admission earns you a snort and a laugh as he draws back. "You should," he murmurs, and he sits up as if you're playing some stupid game with him, as if he actually wants you to hit him. A part of you thinks he does, and another part really wants to.
or:
The one where Mark's your annoying ass roommate you let hit after a few hits.

Summary
Mark Grayson's day was horrible, he fought a viltrumite that threatened to kill Amber, he got beaten up, his girlfriend broke up with him. And to improve his situation he received a mysterious call to go home, because his mother was being held hostage along with his brother by a crazy man who was saying that he did something he didn't do. And now he's trapped in a universe similar to his, except... zombies. The putrid smell made him want to vomit.
Y/n didn't have a very good life either... and now she had to survive in one of the worst moments of humanity. Why did the end of the world have to be a damn zombie apocalypse?... Wait, that guy is wearing a ridiculous outfit... My God, he has a huge ass.

Summary
You are stuck working another shift at the comic store. You love working there, but it can get boring when no one shows up. Suddenly the door opens and a cute guy walks in, now is your chance to talk to him, because he looks pretty familiar.
This is my first fan fic so please let me know if you have any suggestions, still getting used to the format so future chapters might look different.
