Her abilities are described as having "super strength, super speed, and super popularity". She has a magical lasso she uses to tie up her enemies and bullet deflecting bracelets.
She is a parody of Wonder Woman, right down to the uniform she wears and the magic lasso. "Gal", a slang term for "girl", was chosen because there are already several characters in the DC universe with the codename Wonder Girl. Concidentaly, "Gal" could also refer to Israeli actress Gal Gadot, who currently plays Wonder Woman in her film appearances.
