Here are the top four winners of the last poll, and as promised here are the ideas I have for each world. I won't reveal too much about the characters to avoid spoilers, anyways, vote!

DC - Young Justice: Mana Incarnate

Magic is not meant to be alive.

It is meant to be wielded, studied, feared, and controlled.

After dying in his own world, a man awakens in a new reality as something that should not exist within it: an Anodite. A being of pure mana in a world where even the greatest sorcerers only borrow fragments of the forces he embodies.

As heroes rise and villains plot in the shadows, he finds himself caught between two worlds. Too human to be a force of nature. Too much a force of nature to remain human forever.

Timeline: A few months before the team forms.

Game of Thrones: The Sovereign's Roar

Power is a curious thing.

A wise man once said that if you can make a man believe it was his idea, he'll thank you for using him.

Westeros is full of proud men convinced they're the heroes of their own stories, the protagonist to their own tales. Kings, lords, knights, and conquerors all scrambling for power.

As the second son of Tywin Lannister, armed with memories from another world, he intends to remind them of a simple truth:

The most dangerous man in the room is rarely the one sitting on the throne.

Timeline: He's older than Tyrion, but younger than Cersei and Jamie.

Naruto: A Field of Blood

After dying, a man from our world awakens in the Hidden Leaf as the firstborn son of Hatake Sakumo.

He finds himself in a world that used to be nothing but nostalgia for him. The future is familiar, but the present is anything but. The Great Wars are still approaching, legends are still children, and the world is far more brutal than any story ever showed.

In an era where strength decides everything, surviving long enough to reach the beginning of the canon story may prove harder than changing it.

Timeline: He's a few years older than Kakashi.

Seven Deadly Sins: The Gift of Chaos

Chaos created everything—

The world, the gods, the mortal races, the beasts that roam the land, and the saints who inspire it. Every life, every fate, every possibility was woven into its design for it was theirs to change and weave.

So when a soul arrived that was never meant to exist, a soul beyond its grand tapestry, Chaos did what it had always done.

It adapted.

And in its endless curiosity, it bestowed upon the stranger a gift.

Timeline: During the First Era of the Holy War.
