'Crisis on Earth-X' Begins with a 'Flash' Wedding

It's finally here, the annual crossover event that finds Supergirl, Arrow, The Flash and DC' s Legends of Tomorrow all joining forces.

In the end, did they make the right decision for how they'll deal with these people?... more

Should Lena Become the Next 'Supergirl' Villain?

The story of Lena Luthor has been a complicated one on Supergirl. The sister of Superman's greatest enemy, Lex, Lena has become Kara's greatest friend. (Although Lena is completely unaware that Kara and Superman's cousin, Supergirl, are one in the same.) Since her introduction,  Supergirl has played with Lena's dark side and teased that she might be become as villainous as her brother and mother, Lillian. more
