Summary
Mark is still perceived as a relatively normal, human man on Earth. Humans don’t have secondary genders, they have no heightened senses to pick up on pheromones or detect heats or ruts. So, Mark has spent all of his heats alone.

Summary
After the Guardians of the Globe were murdered by an unknown assailant, Mark Grayson thought his entry to superheroing would be simple— fill in the gaps. Only the 'needs' you can fill are different if you're a pup, or an omega (by choice if not design), and he's got way too much ground to cover in figuring out exactly what his role would be.
He hopes it'll be with Rex, the cocky alpha who flirts like crazy and doesn't seem to mind Mark's brand of omega.
When the GDA doesn't know what to do with you, it's up to you to figure out your place, right?
Or,
Viltrumites are violent.Omegas are sweet.
What if Mark's both?

Summary
Mark loses his fight against his father, after his mother and friends are threatened. He's to be brought to meet the remaining Viltrumites, because given his unique biology, his existence is imperative to the empire. As a male omega, something that hasn't existed in the Viltrum empire for thousands of years, he'll be expected to be mated and to have pure blooded healthy Viltrum children.
Mark doesn't know who Conquest is, or why even his father seems disturbed by the news of who his mate to be is.

Summary
How do you change a Viltrumite? And what happens when you do?
Mark gets his wish-- but then he realizes 'alpha' isn't all it's cracked up to be, and he decides to be an omega instead. Relationships fail, friends are lost, but his dad will always be there. Right?
At last, Mark had presented. And still, his wife was not pleased. Nolan bristled. "You're worried because our boy smells like blood?" Nolan rolled his eyes. "He's a Viltrumite. That's going to be half of his scent no matter what."
Debbie frowned. "He's supposed to heal faster."
"I don't really see what the problem is." Nolan sighed. "First you're worried because he smells like a nursing child, and now you're worried because what. He smells like a battlefield?"

COMIC SPOILERS!
An explicit collection of all the ficlets I’ve accumulated while enjoying this series… and actually finished.
The majority of entries are whump/angst, so be warned. Just about all of them involve Thragg and Mark, since I’m always a sucker for villains liking their heroes a little too much lol

Summary
Under the blight of the baleful half-moon, this fleeting breath would mark his soul till the last sea drank dry.
Alpha, his heart purred, though his instincts screamed human.
Cheek turned in longing to adamant hand, sure as law and twice as warm. Bent on his knees, eyes summoned skyward — mind sinking like lead into blue, blue, blue.
Or: Mark learns about his unique Viltrumite biology. Takes place at the start of S2. A/B/O.

Summary
Mark Grayson is a rare, unclaimed omega among the Viltrumites, and he’s dangerously late for his first heat. While everyone anticipated that Nolan—his own father—would claim him, Nolan has abandoned him. Now, the empire has sent someone far more dangerous.
Conquest.
A strong alpha, feared even by the high council, arrives with a singular mission: to bond the omega before he unravels entirely. Mark is furious. Defiant. Unwilling to bend to anyone’s will. But Conquest isn’t asking for Mark’s compliance—he’s taking it.Mark finds himself trapped in a world of power dynamics he never asked for, and Conquest’s dark presence is impossible to ignore. As Mark’s heat takes hold, he begins to realize that resistance might be futile—but he’s far from submissive.
And while Mark is caught in this web of dominance and control, Nolan—imprisoned and filled with bitter regret—watches from afar. He’s consumed with jealousy, unable to accept that his son has been claimed by someone else. He’s plotting a way to reclaim what he believes is his, but Mark might not be the same boy he once knew.

Building a new scent by kimcavoy

Summary
Mark is 17. He was causing trouble, Cecil fears this is not entirely unusual, but when a teenager retreats into his hospital room and whines or growls at anyone who tries to get him out, then the alpha in charge must take action. Mark needed an authority figure to make him feel some protection. He needed an alpha. God help and forgive Cecil, but he believed Mark needed him.
Mark is 19. His cheeks are flushed. Cecil hands him the pillows, obeying the kid's wish, saying nothing. Mark doesn't want to talk. He wants comfort. He smells like a new, fresh fruit, something that comes from beyond the planet, stardust. A young omega seeking comfort from the worst alpha he could have chosen.
Mark is 21. He with all his strength, with all the times he tried to impose himself on Cecil, fails at the simple task of mustering the courage to beg for what he wanted. He looks imploringly at Cecil, begging him for anything that'll calm the chaos in his head. Cecil smells like the kind of alpha Mark needs, and he throws his head back, ready to be marked.
Or: Three nests. Three canon divergences. Three times where Cecil and Mark build a nest trying to find an answer to the emotion that arises in between.

Summary
“Hey Grayson!” Todd shoved his way through the milling student body, eyes focused on his target.
Suddenly Mark slumped all his weight onto the lockers with a gasp.
“I’m talkin’ to you Grayson! You deaf now or something?” The Alpha bully fisted the collar of his shirt.
There was an underlying tone in Todd’s voice, a command laced in his first sentence; one that had Mark turn his head in submission and whine.
Mark was presenting. Mark was an Omega. And he was entering his first heat.
