Summary
The man above you released a chuckle. It was a rotten sound, decayed and bitter. Brutal. Sinister.
“You know,” He began, tone sharp. “She may fight—and it is so pretty when she fights…But, at the end of the day, she loves the things we do to her.”
Your stomach churned, a resounding chorus of identical laughter from more men behind you. Your boyfriend glared at the reflections of himself, sizing them up. But, no, you couldn’t let him do this.
“Just go, Mark. You can’t take all of them,” You whispered, tears pricking the corners of your eyes.
Sinister’s hand tightened at your roots, jerking your face to level with his. You yelped, squirming as he gripped your cheeks with his other hand. He kept you facing your broken boyfriend, locked in on his tortured gaze. Sinister released a low chuckle, squeezing your face before purring, low and cruelly,
“But you know who can?”

Summary
He lied about being a superhero. You lied about not having freaky ass mind powers. You broke up- bitterly. End of story. No shot Invincible and some superpowered grunt for Machine Head would ever work out in any reality. Except. When he comes in droves, hoards of himself, brokenhearted and wanting, wrecking cities for a chance to get one last glance at you.

Summary
Debbie knew that her son was not like others when the silence followed him. Mark Grayson didn't understand the world, he didn't understand the feelings within him that lurked since birth, and he didn't understand William Clockwell. Even when he would be the quiet kid, when he would utilise his powers for things that would make people feel revulsion if they ever found out, he realised more and more how he needed William when he grew older.
It was true that the world didn't make sense, but William helped him to understand. That was all that Mark needed, and the rest of the world could burn.
(Sinister x William)
A/N: It's about Sinister growing older and then becoming Invincible, and his developing relationship with William. It's inspired by 'aDistraction2406' with their fanfiction 'Made For'.
