The Help question

So, I read these books a long time ago and I cannot remember their names or the author who wrote it. It was about like 4 teenagers getting kidnapped by supervillains and at first, they strongly disobeyed them but eventually they befriended them, and the villains gave them superpowers. Then eventually after being strong enough to defend themselves, the teenagers turn away from the supervillains and join the heroes. I can't remember much after that but nothing I'm searching up gives me this information so please help.
