The Powerpuff Girls Are Adding a 4th Member 

have been comprised of three sisters, Blossom, Bubbles, and Buttercup. Created in a lab thanks to a combination of sugar, spice, everything nice, and just a touch of Chemical X, Professor Utonium created the three–

Well the Professor and his super-daughters as well as the City of Townsville at large are all in for a pretty big surprise, because there is about to be (or always was, the lore is unclear) a fourth Powerpuff Girl. Cartoon Network just released this image to tease the big reveal:

So we don’t know much about this Powerpuff apart from her long locks, but we won’t have to wait long to get the skinny on the mystery sister. Cartoon Network is releasing a five-part movie event called

Sunday, September 17 at 5:30 ET/PT. It’s not clear who this fourth member is, how her origin story relates to that of Blossom, Bubbles, and Buttercup, or if she’ll even be sticking around the City of Townsville long to help fight evil.

However, it doesn’t seem like she’ll be fighting

the girls (though you never know what nefarious, sneaky tricks the villains of Townsville are up to). Cartoon Network says this epic event kicks off when the Powerpuff Girls’ life as superheroes are turned upside down—and all four Powerpuff Girls must band together and use their strengths and smarts to save their beloved city of Townsville from forces of evil that are bigger than ever.
