In the year 7000 scientists made every human being with the same colour heart. Pink. But later did they know that the colour could change. Only 10 colours. Nothing less, nothing more. But the first time the colour changed in these 10 people they had no clue how to use there power. The government caught them when they were in middle school. They realized it changes in middle school, and they can't explain why. So when they caught them, they were killed. After another 14 years another billion was born. They got caught and so on. But just recently the 10 people new how to use there power. They heard the news about the color change so when it happened they trained to see how to use it. When they were training, they all met. Then once they figured it out the started attacking the government. But they failed. That was the only group who was almost won. Now another 14 years past and the 10 are just figuring it out. It's harder for them sense there are police men/women all over the middle schools.
But you arrived just in time.
