After exiling himself from Cybertron, Megatron travels the cosmos, looking for a new purpose in his life. However, a meeting from an old friend gives him a new mission: instead of conquering a world, he must save it…by helping one girl regain her fire. This task will give him a chance at something he desires, redemption, and perhaps…something much more.

The Master Chief sacrificed himself to save humanity from Didact but at what cost, he lost his companion, his good friend companion, Cortana. He thought that he was dead until by some unknown force, he was sent back to the past. There the Spartan awakens to a different 21st Century Earth. How would his presence affect everyone? What will the Spartan do?

They tried to destroy him. They failed. He was changed. Thrown into an unknown world of bloody evolution. Now he must make his way through this new land and show just why he is known as a god of destruction and the King of the Monsters. May God help them all. Faunus Godzilla!

Optimus Prime always has been and always will be a hero when Cybertron demands it, but when his home world no longer needs him to save it, the time has come to enjoy life as it was meant to be lived. Thus Orion Pax is born in the human world and now seeks a new goal in life. He may be burdened with loss and regrets, but that's all the more reason to live. He can still do good.

Just when his victory slipped away, something unexpected happen the Megatron along with two of his most loyalist men. The three got transported to another world and were now humans. Will they continue their goal of conquering or will they find something more meaningful than power?

The conflict between an ancient empire and a modern military from another Earth was foreseen by many to be a strange affair. However, unknown to even both sides, the people of Falmart will find themselves joined by an unfamiliar third party, who come from a place that was least expected: Beyond the stars. The Autumn has risen, and the UNSC will leave its mark on the exotic world.

After merging with the core of his planet, Optimus thought his quest had came to end; however, it wasn't. Now he must save the people of Remnant from a rising darkness and Grimm. Will he light their darkest hour with his new comrades or fail to complete his duty?

For a long time, the Grimm and the Hunters of Remnant were in a stalemate. But that was changing. New species of Grimm are emerging. Unfortunately for them, there's a new hunter who's already all too familiar with how to fight them.

What happens when a legend comes true and monsters from another world start pouring into Remnant. Monsters that even the Grimm are scared of. Team RWBY and a new friend have to go on a journey to kill the creature responsible and revert everything back to normal. But of course, nothing is ever that easy. A Monster Hunter meets RWBY fic, done for a friend. T for future violence.

Being reborn was not something Tatsumi ever expected to happen to him after his death by Esdese hands. Now in the new world Tatsumi enjoys living a peaceful life... but peace doesn't lasts forever. Does contain Spoilers for AGK and Highschool DxD.
