Bleeding Cool has been running a number of rumours on a number of creators leaving their DC New 52 books with issue 15 or 16, some moving to other books, some seeing their books cancelled, some just leaving full stop, and a whole bunch of new creators coming in.
The latest, and rather confirmed this time, is Brett Booth, about to start work on his final issue, Teen Titans #16. He writes;
Also just finishing up TT 15 today. I should be starting my final issue next week!
Brett Booth has drawn the book since the New 52 reboot, with Scott Lobdell writing. Whether Scott is also leaving the book, or where Brett is going, we may have to wait a couple of months to find out. Or NYCC… he does indicate that it’s a solo book, and that he was offered Scott Lobdell’s Red Hood And The Outlaws.
