Every Titan has had solo except Beast Boy(who has had a mini series) I believe so try again. With or Without Justice League he is a recognizable character. Anyway I will keep same things over and over I don't know how you expect Cyborg solo to be successful when they strip the most important elements and tell the same rehash I am human or machine story in a comic with generic tech villains and almost every issue had a different artist many of which aren't good. No character not even the big guns can sell with that happening to them. Once more editorial can sink a book and Cyborg is a master class on the topic. Anyways I have side track this topic enough I will probably make a topic to talk about this point.
