in the wake of Legends of Tomorrow uncoming debut, I think is time to give Rip Hunter, Time Master a new series. Or a first series, I really don't know if there has been a Time Master previous series.
First, to take advantage of the multimedia synergy (whatever that means) by having a comic with the character on it.
Second, to give the post Flashpoint universe some semblance of history. We know how much necessary is that. A series with a time traveller exploring time could help to rebuilt that idea, at least partially.
