Summary
Mark Grayson hates his life. His dad is making him take over the planet and his hearts just not in it. Then he loses the only thing that made his life in anyway bearable. So when a disfigured man gives him an opportunity to hop dimensions to a world without his farther and his darling boyfriend is still alive? He double crosses him and takes that ungrateful version of himself’s place but it wasn’t exactly what he’d expected. That can be changed though. Everything is going to perfect.
William was doing pretty well for himself; the best boyfriend he could ask for, loving parents, good grades, perfectly intact and unbroken bones. What could possibly go wrong?

Summary
William Clockwell and Mark Grayson became friends because their mothers worked together, and it was common for them to spend time at each other's homes while their mothers collaborated. This constant presence made it inevitable for their bond to deepen.
When William came out to Mark at the age of 14, he trusted him completely, believing he was confiding in a close friend. However, he did not realise that this moment would become the catalyst for a slow-motion tragedy when Mark seemingly accepted William's sexuality.
Mark, grappling with repressed feelings and a bruised ego, spirals into a tumultuous mix of silent obsession, fractured loyalty, and a gradual descent into a godlike ego, consumed by desire for conquest.
OR A variant Mark who is more of a chud and he can't handle William being gay that it somehow became William's problem.

Summary
With so many possibilities that could determine the path for Mark Grayson and the Earth's very fate, William Clockwell learns one common factor that each evil variant was missing or lost compared to his Mark.
It shouldn't have been the case. At least to William, it shouldn't have been, but several versions of him tell him otherwise.
INDEFINITE HIATUS/DROPPED
A/N: Unfortunately something happened that's not devastating or is related to this fanfic, but it was the one I was writing through this journey that blew up into something I was forced to witness. It ruined the experience, so I won't continue this fic for those reasons.

Summary
A few off hand mentions to people, a few stories that slip through. These things are what made Mark realize something about him was different. He always knew him some ways but it was like a specific light switch had been turned on, leaving him in a room that was isolated from everyone else.
OR
Mark Grayson has DID and isnt aware.

Summary
William isn’t an idiot, he knows Mark is keeping something from him and he wishes he’d stop noticing these new walls his best friend keeps putting up. What’s going on with him that he can’t tell William about? What’s up with this talking book Williams found? And what do you mean the GDA’s taken an interest in him?
Meanwhile Marks trying to find something that makes sense in a world where he just got his powers, the Guardians of the Globe are dead, and his dad’s really set on training him as a hero. But even though he’s a hero now and by all means should get a girlfriend like hero’s in comics do, why doesn’t it feel right? Why do the butterflies in his stomach when he’s close with girls make him uncomfortable instead of feel in love? And what do you mean William will be a hero with him too?
[basically my take on maskless Mark and his William]

Summary
Durante el evento multiversal conocido como la "Invencible War", William Clockwell se ve atrapado en el caos cuando su universidad se convierte en un campo de batalla entre múltiples versiones de Mark Grayson / Invencible. Tras ser salvado de morir aplastado por los escombros por Rick Sheridan (su "casi algo" ), William es "rescatado" de forma abrupta y posesiva por una variante de Mark proveniente de otro universo.
Este Mark, cubierto de la sangre de sus enemigos y con una obsesión protectora y romántica hacia William, lo secuestra para "mantenerlo a salvo", arrancándolo brutalmente de su vida y de Rick. William es llevado a un refugio donde descubre que no es el único: varias otras variantes de Mark (Mohack-Mark, Emperor-Mark, Viltrumita-Mark, Sinester-Mark, Masked-Mark y Fullmask-Mark, omni-mark) han hecho lo mismo con sus respectivos William, creando un harén multiversal.

Summary
William’s mouth hung open, breath expelling on the first syllable of ‘help’ before hard pressure made the plea die before he could make a sound.
For a moment, William thought the freezing cold pressed against his throat was a knife. It was cold and sharp like one, but the pressure felt concentrated like a spike rather than a blade. There was also wetness... As he regained his senses, he slowly realized they were teeth.

Summary
Maskless Mark almost lost William. Existing in a rotting, war-torn world, eventually all that was left was William. So, he hadn't hesitated when he fled through a portal to an alternate dimension away from it all with his beloved. The problem was, that Nolan and the Viltrum Empire were still on the other side - but that hadn't stopped Mark from protecting William before...
A/N: My take on what would happen if Maskless Mark and the Original Mark still met, but Maskless never lost his William.

Summary
Magia. No universo do Invencível esta palavra, de fato, tem significado. Poder. Liberdade. Preço. E William Clockwell conhecerá bem cada um destes degraus que formarão os caminhos arcanos por quais passará, após uma única noite que valeu por toda a sua vida. Um momento de traição. E um de de redescoberta da própria linhagem.
Feiticeiros não são tão incomuns. Entre heróis e vilões, são aqueles capazes de virar o mundo do avesso. Transformando sonhos em sinas. Deformando a realidade com as próprias mãos. Sussurrando desejos que se tornam verdades. E, agora, William fará parte disso. De aventuras que testarão sua índole. De um amor que tentou deixar para trás, mas que sempre clamou por sua volta. Falando com calor... em seu ouvido.
Crueldade ou benevolência?
Luz ou trevas?
Perdão... ou vingança?
Nem Mark, nem Eve, nem Nolan estarão prontos para o peso de suas escolhas. E como poderiam?
Seria a hora perfeita de mostrar se um feitiço tem ou não mais força que um soco de Viltrum.
Ps: Essa história se passa na segunda temporada da animação da Prime Vídeo.
