Well I've often wondered this myself. Could the Wonder Woman mythos handle having a Wonder Boy introduced? I've often wondered why not.
Superman has Superboy and Supergirl (among others)
Batman has had the Robins as well as Batgirls (and so on)
And Wonder Woman has the Wondergirls as well as the Amazons and the Greek Pantheon to an extent. But even with her pantheon Wonderwoman for the most part interacts with the female side Athena etc... unless fighting one of the angry male gods, Ares, Zeus etc...
What does everyone else feel? Should there be a Wonder Boy?
It'd be one of the few times (if any) that a female character inspired a male one and that's one of the reasons I'd like it, especially since way back when they kind of hinted at having something like that with Bobby Barnes, Trevor Barne's nephew who was a huge Wonder Woman fan. He even had a Wonder Boy shirt ala the Young Justice era Wondergirl with a WG on it.
