If I understand the New 52 timeline correctly then Wonder Woman was 18 when she first left the island and 23 now or older depending on how much time is supposed to have past since then. My question is how old is Steve Trevor in this timeline. I got the feeling that he's in his mid thirties currently but I really have no idea. Has there been anything actually stating his age?

i am not sure, how long does it usually take for someone to become a colonel over there in the US. Looks like he has been a colonel for quite sometime

Totally unscientific guess? Early to mid thirties.

He could be from anywhere between mid-twenties to mid-thirties, by that measure, as you can only enter the military here when you're 18 or older; under some circumstances, down to 16; but, I'm guessing he's somewhere in his late 20s to late 30s; definitely a bit older than Diana.

Seeing as how dc likes to make every one younger he's probably like 24

@herrweis: well why would they make him an old ass man? That was Perez's only mistake

Wonder Woman is 23, so I think Steve's in his late 20s like Superman and most of the other Justice League heroes.

I was just thinking how it seems like Steve still isn't over her. If she was that much younger then him that would seem really odd, but I guess to be fair she is Wonder Woman. If he was in his mid 20's when they met it wouldn't be too big of a gap. Not to hate on agegap relationships though. I've actually got a bit of a track record of dating older people.
