Some interesting designs and ideas, but also some not so great ones. Don't really know what to make of it all. I do wonder if any of this will carry over into their books after Future Slate.
Red X showing up feels completely out of nowhere, haha. It is weird how his character only appeared in a couple of episodes of the TT cartoon with one of those just being Robin under the mask, but fans have been wanting him in the comics for such a long time. I guess fans just REALLY love anti-heroes, haha. Having him appear in this event feels weird. I guess it might be Damian? Since he was giving up the Robin identity in the TT book I think.
