Jaime Reyes was trying to take a short cut on his way home from school with his two friends, Brenda and Paco when they stopped at a disused lot so he could get junk for his sculptures. In the trash, he found a blue stone that he thought would make a good paper weight. He brought it home and that night he had a strange dream. When he woke up the next morning, the stone was gone.
Over the course of the next few days, Jaime's life and body started to change, rapidly feminizing until he was a complete girl. She discovers that the stone is an alien Scarab, sent to Earth thousands of years ago as a precursor to an alien invasion fleet. Jaime, who's sister, Milagro, dubs Josephina or Josie for short, fights and struggles for control of his body with the Scarab. Josie ultimately wins, turning the Scarab, Khaji Da, to his side.
Together the two of them perform a series of heroic deeds, catching both the attention of a local Meta human gang, Posse, and a criminal mastermind known only as La Dama. After foiling one too many of La Dama's schemes, she captures Josie's friends and family. The Blue Beetle then teams up with the Green Arrow and together the two of them take La Dama down.
Jaime is a Mexican American teenage boy before he finds the blue stone. But after it bonds with him in his sleep, it slowly turns him into a beautiful teenage girl. Josie has a pixie haircut and a tomboyish style of dress.
Both Jaime and Josie are smart and savy. Kind of shy and bullied at his old school, Josie moves to Brenda and Paco's school and is well liked by his new peers. She has a great sense of justice and never backs down from a fight, even when she know she can't win.
