Superheroine
From wipipedia.org
A superheroine is a fictional female character, endowed with superhuman powers or extraordinary skills. Superheroines are generally drawn with tight and often scanty costumes, made of lycra or latex. They are sometimes captured by villains and placed in bondage.
Among the most popular superheroines are Supergirl, Batgirl and Wonder Woman. There is a particular Wonder Woman bondage semi-fetishism, which was parodied as Blunder Broad. A similar parody of Batgirl is Batbabe.
