With Batman, of course he's had a medley of Robins, with Damian being the latest. And when Damian is written right, he's actually pretty good to read (though that can be tricky).
With Superman, we have Jon Kent Superboy, that is very much his father's son. And is quite popular, and serves as a bit of an opposite to Damian in Super Sons.
Now, I'm not saying Diana has to up and get pregnant anytime soon and whatnot, and I understand many on here want different arcs. But, just to have each member of the trinity have a representation for the "next gen", how would you feel about that? Not necessarily the whole Hunter thing that Justice League just finished up, but either a daughter or son. Maybe getting in on the whole Super Sons thing. Thoughts?
