[Western Crossover] Oh No, I Marked My Boss’s Nemesis!

Lucian Lambert is an ordinary employee at one of Metropolis's famous pillar companies.

...All right, he's not actually ordinary. He's one of the pillars of the Research Department, mainly responsible for developing biotechnologies and pharmaceuticals. He's a key figure in the pharmaceutical development division of LexCorp. Lucian understands exactly what his boss wants and makes products that work well with few side effects. Most importantly, unlike other smart people, he never shows off his intelligence or questions his boss's ideas.

Aside from starting to pack his bag half an hour before the end of every workday and walking out the door the moment his shift ends, Lucian has no flaws. He won't work weekends, not even for triple overtime pay. That's why his boss is happy to entrust him with some of the work on products that aren't for sale.

Lucian knows that his noncommercial products will be used against an alien who is "pretending to be a god, acting superior, and clearly wants humanity to become his playthings and live in bottles. He's an evil schemer by nature." But Lucian doesn't care. For one thing, he knows his inventions can't kill the alien. For another, his boss's inventions can't kill him either.

Most importantly, back when Lucian had only recently arrived in Metropolis, the alien picked up the car he'd bought on credit and smashed the house he'd bought on credit.

In those days, the Justice League hadn't been formed yet, and LexCorp hadn't released alien collateral damage insurance. The insurance company didn't pay Lucian a cent, and the bank didn't reduce his mortgage payments. He still had to pay taxes, too. At his lowest point, Lucian slept under the reception desk at work and drank water mixed with expired flour. He barely made it through by selling his blood, eventually getting a promotion and a raise instead of ending up homeless.

Even so, Lucian doesn't hate the alien.

The alien's character design is great, he's friendly, and he really does protect Earth. Sometimes he even gets Lucian's boss thrown in jail, giving everyone a nice long vacation. Like most people in Metropolis, Lucian watches the alien fly around every day and treats it like birdwatching.

But Lucian never expected his boss to come up with something this disastrous to use against the alien.

In short, the alien is an Omega. A drug concocted by Lucian's boss forcibly put him into heat, and he even lost his superpowers. The alien stumbled away and somehow ended up at Lucian's apartment. As luck would have it, Lucian was in rut. He'd never take a day off if he could help it, so the alien caught him right there.

The alien was strong enough to overpower an ordinary researcher, even without his superpowers. His pheromones were potent enough to make a human Alpha in rut lose control almost immediately. And the alien...

Anyway, when Lucian woke up the next day, he discovered that he'd marked his boss's archenemy. The alien, hailed as the God of Man, was lying on top of him like a cat, asking if they could do it again.

After a long silence, Lucian realized the most important thing was figuring out how to survive.

Not just the now-clearheaded alien, but the other superheroes, too. And most of all, his boss, who had an eerily intense interest in the alien.

Haha, I'm dead!

Clark and Lucian get along well.

As Clark, he appreciates people like Lucian, who are gentle, level-headed, and kind, regardless of Lucian's gender. So when Clark found himself in trouble he couldn't resolve alone and had to ask someone for help, Lucian was the first person who came to mind.

He just hadn't expected Lucian to be home.

Being marked by Lucian was almost inevitable. Clark wasn't especially opposed to it, but there were still a few serious problems to deal with.

For example, how could he keep Lucian from being murdered by his boss?

He didn't want to become a widower before they even got married.

Reader advisory:

An ABO world mixed with superheroes. Overall, it's as lighthearted and funny as ever. A seemingly aloof but already deeply smitten Alpha researcher, Lucian, x the Omega Superboy, the Son of the Sun. There might be pregnancy (looks away). I wrote ABO, so cut me some slack.

Overall, it's a marriage-first, love-later romantic comedy. The ABO setting includes original elements, and the world is somewhat less egalitarian than most ABO settings. The worldbuilding may not be as comedic. There will probably be pregnancy. It's ABO, after all (looks away).

No Superboy is actually harmed. The story is friendly to superheroes. Even when they get picked on, it's only to the extent of a Bats joke.

The boss, on the other hand, might not get off so easily.
