Summary
Mark pushed off the door and sauntered in like he owned the place, dropping into the chair across from Cecil’s desk with all the grace of a hyperactive puppy. "Okay, so—hypothetically—if I said I needed a break? Like, desperately needed one? And if I also said I deserved one?"
Cecil exhaled through his nose, like he was counting the seconds before he lost his goddamn patience.
OR
Mark makes Cecil spend a night in bed with him.

Summary
“I will cease our conquering efforts indefinitely, and give the opportunity to our captured territories to choose whether to join your Coalition, or to remain under the Empire,”
A few Viltrumites looked towards one another, uncertain. Had the Grand Regent gone mad?
“I will take part in negotiations with your Coalition, and aside from that, you will not hear from me and my people again.”
“What’s the catch, Thragg. “
“Your son, the half human one, shows great promise.” He shot a sideways glance at Mark. It made him feel like he was being pinned to the ground.
“For all my benevolence, I demand your omegan son as my mate.”
Thragg looked back to Nolan, who’d become as pale as a sheet.
“I will give you time to think about my gracious offer. If the answer is negative, I shall end you all today and then move on to Earth."
In a blink, he was once again far from the group. All Viltrumites started retreating back to their planet with a shake of Thragg’s head.
“You have until Viltrum's sun sets. Do not be tardy. “
Or
Thragg's crush on Mark stops an intergalactic war.

Summary
“Sir, there’s a version of Mark outside. Asking to see you.”
Cecil feels his stomach clench in apprehension as he looks at the Mark through grainy security footage. Hands behind his head and expression perfectly calm surrounded by reanimen.
No yelling, no cocky smirk, no crazy eyes.
There's also none of the anxiety or anger or any of the complicated array of emotions that Cecil is used to seeing on those features. Just the sort of calm confidence that stems from the complete and utter certainty that he’s the strongest person in the room. Cecil is intimately familiar with that look, since he used to see it all the time.
On Nolan’s face.
Or: MasklessMark isn't evil and he wants to stay. Complicated, heart-wrenching, and sometimes funny things result from this choice.

Summary
"Okay," he said, voice steady now. "If that's really how you feel—then I need you to promise me something."
Nolan didn't hesitate. "Of course, son. Anything."
Mark's expression hardened, his eyes going cold in a way that made Nolan's breath catch.
"Promise me," he said slowly, "right now... that you'll denounce Viltrum. That you'll reject them—for Earth. For us."
There was a beat of silence. A single second that stretched on like eternity.
Nolan's eyes widened.
"...What?"

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.
