"En route to Earth, Kara's spacecraft was diverted by a shock wave from Krypton's explosion and forced into the 'Phantom Zone', where it stayed for 24 years. By the time the spacecraft crash landed on Earth, 'Superman' helped her out of the craft, taking her to be adopted by his friends, the 'Danvers' family.
"The series begins years later when Kara is 24, and learning to embrace her powers after previously hiding them.
