In subsequent decades, popular characters like Dazzler, She-Hulk, Elektra, Catwoman, Witchblade, Spider-Girl, Batgirl and the Birds of Prey became stars of long-running eponymous titles. Female characters began assuming leadership roles in many ensemble superhero teams; the "Uncanny X-Men" series and its related spin-off titles in particular have included many female characters in pivotal roles since the 1970s. Volume 4 of the X-Men comic book series featured an all-female team as part of the Marvel NOW! branding initiative in 2013. Superpowered female characters like Buffy the Vampire Slayer and Darna have a tremendous influence on popular culture in their respective countries of origin.
