Who do you think Hank Henshaw is?

But I agree that he could be J'onn J'onzz, from what we've seen so far.

While we're on the topic of "good guys" on the show named for supervillains from the comic, I'll point out that Winn Schott, Supergirl's best friend, costume designer, and not-so-secret crush is named for the old Superman villain Toyman . I've been assuming that getting rejected by Kara will be what pushes him over the edge to become a villain this time around, but given the revelation about his father in tonight's episode, perhaps the Winn we know on the show is "junior", and the father will be Toyman on the show.

Wynn's dad is Toyman. Already been cast as Henry Czerny (Mission Impossible, Clear & Present Danger)...

I haven't seen the episodes, but I think is that -- having Belanti at the helm -- the character would probably be reasonably close to the comics, hence I think that it's reasonable to presume he's a cyborg.
The comic book Cyborg Superman hada pretty confusing origin involving a doomed space flight -- styled after the F4 origin -- and him becoming a pure energy being fused with Kal-El's rocket and seeking revenge on Superman for not saving him.
My guess is that this version of Henshaw was military personel injured either during a battle involving Superman or by the arrival of the prison ship -- both would account for his distrust of aliens -- and reconstructed by the goverment (or maybe Lexcorp) to lead the Department, being of of the few survivors of an alien contact/battle.

After this reveal and Flash's season 1 ending, I think Greg Belanti is getting the nerdgasm factor of his series up to 13. Also I'm wondering if this isn't his personal slap to David Goyer's comment about Martian Manhunter being a dull and unusuable character.
