What if

[JaphethCrenshaw]

You were tasked with bringing peace to the world. What ability would you use to do it?

God chooses you, he takes you to heaven and decided that due to your uniqueness, he wanted to trust you to make a difference without him finally interfering with human affairs. You get to choose any ability from any fiction, or just any ability in general.

Downside is that the abilities are genetic and there's no telling what people will do with those abilities once you're gone.

 

[Bimbonium]

Mugen tsukiyomi (don't think I spelt that right). Even if it ends up being inherited, it won't pose a problem, Madara didn't seem to be able to control the dreams people had.

Essentially, let everyone be trapped in their own dreams.

 

[Pumpkin Ninja]

Talk no Jutsu.

 

[Styles]

Rinnegan and become a messiah.

 

[kimb]

The awakened Buddha's ability of enlightenment. If everyone is in a state of perfect wisdom and infinite compassion world peace would be achieved in a day.

 

[Sauce]

Wouldn't really need to worry about genetics if I don't pass my genes nor die

Omnipotence.

If you could offer food, shelter, clean water and energy to every person in the world, that would count as offering them peace. Peace of mind and spirit.

Good point. We often forget the millions of people in real need so we can scream at each other over politics in our twisted attempts at peace.

 

[Fountain]

I would rid the world of all ignorant people, greedy people, liars, radicals etc. etc.

All of the rotten apples basically.

And if i happen to fall under any of those then i will rid myself as well, all for the sake of peace.

I would stop the wars, throw all the greedy and corrupt into the acid dimension, destroy all gangs, and terrorist organizations (ISIS, KKK, Black Liberation Army, etc).
Every nation will surrender their destructive weapons.

I would also help others, including families in 3rd world countries.

 

[Darth AniCetuS]

I will nuke the world and ask god to send them all to heaven.

 

[Xēnovia.]

Ice manipulation if they don't comply the whole world would look something like this.

Even if you manage to somehow get rid of all evil in this day and age, the next generation will have it's own.

There will always be more, it's a constant battle.
