The dolls were originally revealed at New York Comic Con 2015. The lineup was revealed to include the characters Supergirl, Wonder Woman, Harley Quinn, Bumblebee, Poison Ivy, and Batgirl. Unlike their predecessors in Monster High and Ever after high, these dolls were revealed to be self standing strong dolls. Mattel explained how they'd asked girls what they would like to see in a super hero doll and they said that they didn't want the dolls to be too girly and fashionable and that they wanted them to look strong. Starfire, Hawkgirl and Katana were released later.
