You activate your powers and suddenly find yourself in an unfamiliar present. Within minutes, the Global Defense Agency locates you, having detected the disruption caused by your arrival.

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
Сказать, что все было хорошо, значит соврать.
Жизнь Рекса в последнее время складывалась до неприличия плохо. И это он даже не принимает во внимание свое детство, что было наполнено голодом, насилием и воровством. И конечно же он не вспоминает подростковые годы жизни полные стресса, тренировок, боли и разочерований. Нет, Рекс смотрит в настоящее. Смотрит туда, где вроде все должно быть прекрасным, светлым и многообещающим. Герой подрывник смотрит туда, где он герой, где он достаточно сильный, чтобы сражаться за себя и других, где он, Рекс, сам мог решать, что делать и как жить. И вот почему-то в этом вроде бы светлом настоящем с каждым днем становилось все темнее и темнее. И света подрывник не видел.

Summary
Aveces parece que le pedís al universo algo y quizás te da mas de lo que alguna vez pediste, aunque quizás venga en forma pseudo alienigena.
William no tiene la mejor vida del mundo, lo sabe perfectamente, siente que tiene que cargar con cosas que cree que nadie de su edad debería, aunque por momentos piensa que se lo merece. Hasta que aparece un simpático y parlanchin niño de ojos marrones y cabello negro, que poco a poco hace que su perspectiva de ver las cosas cambie, con una linda amistad de por medio.Es la primera vez que escribo un fan fiction en 8 años, y la verdad no me costo tanto, pero espero poder una historia decente para un fandom pequeño (que amo mucho) que siento que necesita muchas mas historias interesantes, agregare etiquetas a medida que avance la historia.

Summary
So, this is essentially just a retelling of both early one punch man and invincible, but with a focus on the interactions between characters from both. Will probably be a bit more Saitama focused than anything else, but is also going to lean into Invincible territory where necessary

Summary
Well, it's basically what it is ikyk
It's a Debbie and Cecil Stedman fanfic.
Couldn't help myself lads
I mean Cecil is normally laid back, unaffected guy even when his life is threatened that it's hard to tell if he cares about others (side eyeing Donald here lol) but haven't you noticed how he treats Debbie?
Be still my heart.
He's very open with her, willing to support her, takes very good care of her and is such a shoulder she can rest on. Even hugging her in times of her personal traumas.
Like ooofff, these two need to get laid so bad at this point hehehe -

Summary
Where did Cecil come from and what shaped him into the man he is now?
This is a journey through the defining years and moments of his life, from early childhood to adulthood, ending when Cecil faces Mark in that stark white room.
