Flame's Various TNT Duo Oneshots

And They Were R I V A L S

AU: Superhero
Warnings: Violence, emotional manipulation, toxic relationships, implied stalking, implied/referenced neglect, referenced bullying, possessive behavior, feral behavior, smoking, swearing, and just in general Quackity being a bastard. Also implied smut, I think that's how that works? Like I didn't show anything on screen besides general heated kissing and mentioned bites/bruises n' such. But they definitely fucked.
Description:
Wilbur and Quackity have been rivals for as long as they've known each other, ever since their first day of hero school. Quackity has always pushed him to work harder, do better. And to most people's surprise, Wilbur actually enjoys their rivalry for multiple reasons.
But Quackity never failed to bring out the worst in him. He didn't consider himself a good person around his rival, and it doesn't help that he's still obsessed with the shrike bastard even after the other became a villain. Wilbur couldn't let go.
So when Quackity breaks into his apartment one night, one thing leads to the other. He knows the villain like the back of his hand, but Quackity knows him just as well.
Wilbur isn't a good person. There's a side of him that's possessive, greedy, and dangerously protective. A side of him that's all fangs and fire. A side of him that refuses to let go once he considers something or someone his.
His former rival is determined to drag that monster out of him. Determined to make him fall just like he did.
Wilbur can't fight it, knowing that at the end of the day he'd follow his rival to the ends of the earth.

Author's Notes: This is literally my longest oneshot to date and it's my first time writing something with this much tension and toxicity (outside of Apex Predator). It strayed away from it's original concept very, very far and now it's become this toxic nightmare. This one is long, this one is detailed, and these fucks are incredibly toxic.

"Okay, I want you to go in there, and I want you to tell them that they shouldn't have rivalries with other students," the teacher stated, stopping in front of the class's door. "Just. Okay I know talking to students isn't exactly your thing, but you're one of the most well known heroes with a rival."

Wilbur, Pro Hero: Apollo, couldn't help but think that this lady had the completely wrong person to tell students that they shouldn't have rivals. But he was getting paid for this, so he smiled.

"Read ya' loud and clear," he agreed, tail swishing behind him in vague excitement.

Yeah, she had the wrong person to talk about this. But that didn't mean he couldn't be excited. I mean, c'mon, not every hero could claim that they taught something to the next generation of heroes.

Course, apparently he was dealing with a problematic class.

But, to be fair, he had to deal with Quackity in the shrike elytrian's teenager years. He'll be fine. These kids wouldn't know 'problematic' if it bit them in the ass.

The teacher sighed, opening the door for him, and allowing him inside. She cleared her throat as she walked in behind him.

"Alright class," she said, sounding like the life had been drained out of her just from walking through the door. "Today we have The Rising Hero: Apollo with us today to discuss the topic of rivals and rivalries. Please behave yourselves. I will be sitting out for this class, however, Apollo has been instructed to inform me if any of you start acting up. I'd rather not have to send any of you to detention again."

She sent a pointed glare at certain students before smiling, "Now then, I'll let you take over. Do let me know if they start misbehaving."

"Gotcha," Wilbur agreed, smiling as she left the room. Once she was gone, he stepped up to the podium and laughed. "Okay so she picked the entirely wrong person to teach a class about why you shouldn't have rivals. I am the last hero she should've asked for this."
