The un-announced sequel of I Am Number Four (2011), The Power of Six, based on the novel of the same name, has no release date, or any other information. Scriptwriter Marti Noxon explained in a interview on 16 May 2011 that plans for the sequel have been canceled due to the poor box office performance of the film.
The Power of Six would continue to follow John, and Number 6 having left Paradise, Ohio to flee from the Mogadorians.
The movie would also introduce new Garde members, Marina (Number Seven), Ella (Number Ten) and Stanley Worthington (Number Nine). I so wish he would do the sequel
