Summary
For seventeen years, Ben lived a quiet life in Chicago with his mom and sister, carefully managing a strength he barely understood and dodging questions about a father he never knew. He was content to keep his head down, his body in the sky, and sketch the skyline, ignoring the escalating superhuman chaos broadcasted on the nightly news.
Then he met Mark Grayson.
He made the choice to enter into a world of hyper-violent planetary defenders, covert government agencies, and the blood-soaked reality of being a superhero, Ben realizes that ignoring his abilities is no longer an option. As the threats facing Earth escalate from costumed bank robbers to apocalyptic alien conquerors, Ben has to figure out exactly what kind of hero he’s willing to be. He can’t force the world to be kind, but he has the power to force it to stop—he just has to survive long enough to figure out how.

Summary
Mark is taken to Viltrum by his father once he presents as an omega at the tender age of nine to be raised as a Viltrumite. The day he becomes of age, Invincible is prepared and willing to fulfil his duty to the empire as both a warrior and the Savior of Viltrum, choosing Conquest as his mate. Even with the older Vilturmite’s bloody reputation of devouring any potential mates, Invincible isn’t deterred to raise their offspring to be the deadliest warriors of the empire, no matter the cost… But his not-so-suppressed human side does make it difficult.
Or waiting a couple of months for Angstrom’s Phase One to begin with other alternates of himself, gives Invincible plenty of time to reflect on his own life. -

Summary
This is the Scourge progression and details I used for the third chapter of Under New Management, which you can read here.
Feel free to use and change for your own fanfic. I am so starved for Scourge related content in general, so if anyone actually decides to use this, please let me know by using the inspired by feature here or letting me know on Tumblr! I would absolutely love to read what you wrote. Feed a fellow starving fandom member lol.
I also cross post to Tumblr. If you want to check out what I post there you can find me at @xeeforxeon. I usually post my fanfics and some additional memes, ideas etc.

Summary
The war spiraled out of control. Fists gave way to science, leading to viruses spreading beyond intent, containment, and any cures. Alone in his dead universe, Mark lived out his days in increasing ferality until a freak lightning storm teleported him back in time - to a Viltrum in the midst of its purge.
"Grand Regent," Kregg began, a rare note of uncertainty in his voice. "There is a... situation."
"Report," Thragg ordered.
"A rogue element has emerged on the planet. It's defying your will."
"How so?" the Grand Regent asked.
"It's protecting the wounded," Kregg said, "and has taken several children and a youth captive." -

Summary
So, the baby was purple. That was cool.... He really wanted to ask. But he wouldn't.
"He's purple because he's half thraxan." Mark answered, seeming to read his thoughts, with an amused expression.
"Ah, m'kay." He had no idea what that meant, but he would nod anyway. "So, why am I here?"

Summary
304.37 days.
7300 hours.
438,291 minutes.
And yet, there she was.
“You were dead,” Mark Grayson said, voice brittle and cold with shock.
The woman stared back at him, her gleaming eyes all too familiar. They were the same pair in his nightmares—the ones that chased him from his sleep. Those sad, hollow eyes stared back at him with a flash of regret before they hardened.
“A part of me, substantial and great, did die,” She said solemnly. The Director cleared his throat, gaining Mark’s attention. Right, he remembered, this wasn’t the reason he was here.
“This way, please, we've got work to do and a planet to save,” Cecil murmured, eyes narrowed in on Mark. The Viltrumite opened his mouth, anger, hurt, and confusion pulsing through him. Cecil knew? She knew?
“Don’t,” She interrupted sharply. “Not now. Not here.”
Later, she seemed to say with her eyes. And Mark could do nothing as she turned on her heels and strode into the conference room. And so Mark followed, mere steps behind the woman he’d buried and mourned 10 months ago.Savannah Fawn.

Summary
After his death, the past actions of a reformed Conquest come to claim the only thing he’s ever loved. Despite once being human, the synthetic viltrumite transcends dimensions to secure her goal in revenge. After a hundred years of taking on Mark variants and her own vices, Rose finds herself trapped in a new world. While there, she gains the chance to save the viltrumite who bears the same face as the one she lost. He's far less tame this time around, but luckily so is she.
