Writer Brian K. Vaughan has claimed that he had only planned to write "Runaways" for six months (six issues), but because of the popularity of the series and new ideas from Vaughan, Marvel decided to continue issuing it on a monthly basis. In 2007, Brian K. Vaughan announced his departure from "Runaways", deciding to leave the series at the top of its game. Longtime "Runaways"-fan Joss Whedon was hand-picked by Vaughan to write an arc and finish the second volume; although Whedon had declined at first, he later accepted.
