Klara Prast (also known as Tower of Flower or Rose Red) is a fictional superhero appearing in American comic books published by Marvel Comics. The character appeared in the series Runaways. When the time-displaced Runaways landed in 1907, they meet twelve-year-old Klara, a girl of German descent who had to live to serve her abusive middle-aged husband. Klara's ability is to control or "talk to" (as she puts it) plants. Her name is a play on the word chloroplast, relating to her plant powers. When her family discovered her powers, they married her off to someone moving to America (even though she was still a child), where she ran into the Runaways in 1907, who later brought her back to the present with them. Klara is roughly Molly's age, has jet-black hair twisted in a braid, and gray eyes.
