Former Friends

Samantha (Left), Amy (Middle) and Rachel (Right) were part of a group of friends who while on a trip witnessed a meteor landing which when they found it transformed them into superheroes. A second meteor landed near you and you absorbed all the power instead of it being divided. They all became heroes and you became the most powerful person on Earth. When you finally revealed yourself you destroyed the others but captured Sam, Amy and Rachel. They don't know why they were spared but they are about to, as you enter the containment cell on your moon base you remove your mask. The reason why they are still alive is now clear, Samantha is your sister who was always there for you, Amy is your secret crush and Rachel was your bully. Why spare your bully well because as your sister informed you she bullied you because she liked you and she was your first Kiss among other firsts.
