In America, there were children.
These children, were overdeveloped.
The government called them Meta Humans.
Meta Humans had special abilities (the main character can move metal in any way he likes).
The government took them all, and put them in tests, and made them fight.
As they grew up, they realized this was not the life they wanted to live.
They escaped, and started an organization.
That brought all Meta Humans.
They travel through different dimensions.
To find a home, a place to protect all Meta Humans.
The American government is always after them.
One day they will find a home, but hopefully that's before the Americans destroy them.
