I am Uatu the Watcher and I have watched Earths mightiest heroes overcome the greatest of challenges. But, when they could not stop a certain threat it cause many of them to be transported and stranded on an world that is going through it own crisis. How will their presents change the fate of that world and what lessons can they teach the last master of Chaldea.

The cast of Fate/Stay Night watch Fate Hammer Time by TedTheRabbit

Ya no quedaba nada en ese mundo. El único sobreviviente de un infierno en llamas fue salvado por la persona menos esperada.

Shirou Emiya wanted to become a hero. That was clear to all who truly know him. For a long time though, he lacked the power to actually achieve that goal. No longer. No longer will he lack the power, now that the Hammer of the Odinson has chosen him as new wielder. Prepare for Thunder. ShirouxMultiple, Thor-Shirou.

What if Tony Stark had a son? What if that said son was not only a genius like him but had a certain deck of heroes? What if they met before the events of Loki's invasion and the birth of the Avengers? Before Peter Parker donned on the mask of Spider Man? Before they found Steven Rogers? His name is Xero Stark and this is his legend.

with the holy grail war taking a turn Shiro, Rin and all their friends must now assemble alongside their new servants and the overseer of the war to fight back Medea, her captive servants and other evil hidden in the dark Fuyuki's shadows to try and save everyone (sequel to Fate Stay Daredevil Justice is Blind rated M due to elements of the Fate Series)

Lancelot Du Lac, was a dead man. He was never meant to walk the earth in corporeal form. He was never meant to encounter any of Earth's Mightiest Heroes - and he most certainly was never meant to get involved in fighting - or in this case dismembering - crime. But hey, when life drags you kicking and screaming out of the afterlife, you make due.

Hakuno Kishinami has finally won the Holy Grail War and made her wish, and now she's being torn apart by the Moon Cell Core. Meanwhile in another universe two sisters have to deal with the fact that they're Mutants.

Ten years have passed since the last Holy Grail War, and the world has changed. The Age of Marvels has come, and with it a new Sorcerer Supreme. The Fifth Holy Grail War has arrived in New York, and one Friendly Neighborhood Hero finds himself at the center of the struggle.

Taken from his home by unknown Magic, Shirou Emiya is deposited in a reality much similar to his own. Except it is protected by Earth's Mightiest Heroes. Armed with new power and purpose, watch as his destiny unfolds and that being a hero spans more than just one world. His destiny is no longer his, for now that he is branded, he will become a champion of many worlds. [HIATUS]
