DC announced it is launching a new Robin series in April, as Damian Wayne looks to sever his ties to both Batman and the Teen Titans.
Writer Joshua Williamson ( The Flash , Future State: Justice League , Infinite Frontier) and artist Gleb Melnikov ( Wonder Woman , Batman/Superman Annual ) will collaborate on the new ongoing series that promises new mysteries for Damian to explore, a new supporting cast, brand new characters and lots of fighting.
I didn’t even notice there was a character next to Rose but your theory makes sense. I was referring to the character to the right of Jericho, light blue in color with skull face paint and what looks to be bones on their sleeve. I believe it’s the same character on the 1:25 cover.
Both the creator and artist, when pressed, stated that she will NOT appear in any way, shape, or form until Robin #1. That was my first thought too when Tynion mentioned he was doing backup stories in those books.
