Summary
Well, this is unbelievable. First, your best friend, Omega, and now your partner turns out to be half-alien. Then his father becomes a murderer trying to conquer the planet, only to disappear for months... and it doesn't end there. Then your partner goes into space for several more months, supposedly to help a strange grasshopper race, and returns with a purple baby... and of course, it gets even better... several murderous variants invade Earth to make Mark look bad... and well... All the remaining variants want you as their alpha... this is going to be tough.

Summary
What if you died before you could truly achieve anything? Taken by illness before your time, faded away from a unsatisfying life, and then... Given a second chance, your first chance at greatness, destined to become the champion of a world who could surely use one? That is what happened to one Mason Hall, brought into a world unlike anywhere he's ever been, and yet, more familiar to him than one would ever think.
TL;DR: Comic book fan in a world where Invincible doesn't exist gets Isekai'd into the TV show's world, and becomes Hawkman.

Summary
Mark was raised on the planet Viltrum, but on his Eighteenth birthday he's sent away on his first mission. That also happens to be his hardest yet. Conquering Earth and all the humans that call it home. The reason it's so hard? His mother was a human! Now Mark has to build new relationships through lies while still staying loyal to Viltrum. But all of that changes when he meets the love of his life and he starts questioning Viltrum's ways.

Summary
When Rex nearly dies during the Invencible War, it’s a variant of the Invincible who saves him.
Not a hero. Not a kind person. A weird Viltrumite from another reality.
The variant is stranded on Earth, and over time, he begins to infiltrate Rex’s life… slowly, like a silent storm. He doesn’t understand humans. But he seems willing to try, as long as it’s with the one person who made his existence fall apart, the one person worth trying again for.
Not all worlds are created equal. But sometimes, you just need to belong to one.

Summary
Mark Grayson and Eve Wilkins are trying to build futures neither of them feels entirely allowed to reach.
After the collapse of his relationship with Cecil and the weight of his own violence, Mark spirals into emotional isolation, internalized guilt, and quiet desperation. Lost and confused with the trajectory of his life and of his identity.
Eve, still carrying the ghosts of her past mistakes and the government that made her, throws herself into school, philanthropy, and the hard-won task of rebuilding her life from the atomic foundation up. Slowly gaining better confidence in herself to do good with a renewed purpose.
OR
What if Mark and Eve’s Season 3 relationship arc was an actual, centralized slowburn with explicitly parallel arcs?

Summary
La sangre derramada en un ritual desesperado debía invocar a una deidad menor, algo que los héroes de la Tierra pudieran golpear y someter. Se equivocaron.
Una grieta en la realidad se ha abierto, pero lo que ha cruzado no obedece a la ciencia, ni a la lógica, ni a la fuerza bruta que gobierna este universo. La Gran Tumba de Nazarick ha descendido sobre un mundo de capas y acero, trayendo consigo a la Muerte misma.
Atrapado en una realidad donde los dioses son alienígenas y la tecnología desafía la comprensión, el Señor de la Muerte, Ainz Ooal Gown, observa desde las sombras. No busca la paz, ni la justicia. Solo busca la supervivencia de sus hijos... y en este nuevo mundo de falsos ídolos, Ainz descubrirá que para proteger lo suyo, tal vez tenga que convertirse en el villano definitivo que este universo jamás vio venir.
No soy dueño de Overlord ni de Invencible, todos los derechos pertenecen a sus respectivos creadores Kugane Maruyama y Robert Kirkman.
