Grupo X, from Florianópolis, presents X-Who?, the Musical, a theatrical show conceived under the aesthetics of comic books and pop/nerd culture, with dramaturgy and music of its own authorship. Through the theme addressed, the work uses comedy and parody to deal, in a fun way, with controversial issues such as prejudice, gender identity, oppression, intolerance, among others. In a plot in which humans and mutants are on the verge of yet another war, situations common to contemporary society are addressed in a playful and fantastic universe.
