‘Supergirl’ Season 4 trailer unleashed at Comic-Con

Supergirl: Season 4

Kara’s back – with a brand new costume? Or is it Kara at all? The CW has unveiled a new trailer for SUPERGIRL‘s fourth season at Comic-Con, and there’s a few surprises.

We left Supergirl/Kara at the end of Season 3 with some big changes for National City, a reconnection with her mother, and the reveal of a Supergirl doppelgänger somewhere in Russia.

The season will add severa new regulars, including Nicole Maines as Nia Nal at CatCo, April Parker Jones as Colonel Haley, and David Ajala as Manchester Black.

This new trailer tells us very little, and reuses some footage from the previous season, but it does end with the reveal of a brand new costume for a hero. Only two questions remain: which hero is in the suit? And what is it with the CW and helmets?
