Some humans developed abilities that put them more powerful than an average person. Some take advantage and use their ability to do bad.
Some of the people that did not get new abilities don't like the evil beings. The people that don't have abilities fight against the evil people. They do whatever they can to try to get rid of the evil beings.
Ten years earlier, a mysterious object hit earth causing super powers to emerge inside of only some humans. This causes some to be mad and care for no one else.
