Wonder Woman (1975)

When a bolt of lightning crashes through a police crime lab, a mix of electrically charged substances bathes chemist Barry Allen, transforming him into the fastest man alive--The Flash.

The series is set in New Gotham City, several years after it has been apparently abandoned by Batman. In his absence, Huntress, Oracle and Dinah are now the protectors of New Gotham: the Birds of Prey, and had taken over his war on crime. They are joined by Alfred Pennyworth, who serves Helena as she is heir to the Wayne estate; and Detective Jesse Reese, a police officer confronted with crimes and abilities he cannot explain. A central feature of the series is the concept of metahumans: individuals born with powers that cannot be explained. No two metahumans have the same abilities (unless hereditary), and there exists a whole subculture of metahuman society that the outside world knows nothing about.

The world may know them as Wonder Woman, Supergirl and Batgirl, but not-so-typical teenagers Diana, Kara and Barbara, alongside their Super Hero friends have much more to deal with than just protecting Metropolis from some of the most sinister school-aged Super-Villains. After all, being teens is tough enough, what with school, friends, family and the chaos that comes with managing a social life. But add super powers and a secret identity to the mix, and things can get a lot more complicated.

The Caped Crusader is teamed up with Blue Beetle, Green Arrow, Aquaman and countless others in his quest to uphold justice.

The Avengers save the world from the biggest threats imaginable--threats no single super hero could withstand.
