Global Entertainment has posted an international trailer for the new Supergirl series. In the trailer we get a better idea of the setup for the show including how her cousin Kal-El is older than her now when he was younger when they left Krypton. Seems Kara Zor-El's ship was sent off course by a shock wave from the planet exploding and was sent into the Phantom Zone. She was there 24 years where no time passes.
The inclusion of the Phantom Zone in the setup gives the series a source for super-powered baddies in the same way the particle accelerator explosion created a lost of the villains for The Flash.
Supergirl is set to debut on CBS on October 26th.
