We get a lot of questions about this one, both on our message board and
via email. "Hal Jordan is a pedophile" is our own little meme, like
"
Superman is a
dick" or "
It sucks being Sue Storm!" Of course, just
like those, ours has a real basis in the comics.
It started with the character of
Arisia, a 13-year-old GL with some serious
daddy issues. She developed a crush on Hal, and in
Green
Lantern #205 and 206, she
used her ring to physically mature her body so Hal
would like her back. That link has a better analysis of the
situation than we could manage, so go enjoy. Anyway, the story ends
with Hal dry-humping this girl in a cave about an hour after he notices
the change. Big hero.

Several writers kept this relationship alive, which means that Hal
knew Arisia was actually still a child, but carried
on a serial relationship with her anyway. It's recently been retconned
that "13" on her home planet is equivalent to our "240," but that sure
as hell wasn't the case when the character (and the concept) was
introduced.
A more recent example comes from
The Brave and the
Bold #2, where Hal is flying in space with the new Supergirl:

I don't care how hot the girl is, normal people don't need to remind
themselves when someone is underage. Especially not with such...
fervor. I mean, come on, the guy works side by side with Black Canary -
where's the comic that spends pages and pages on him reminding himself
that she's married to Green Arrow?
Although, in Hal's defense, Supergirl did eventually end up dressing
like
this for him, so... wait, I forget how that was supposed to
be mitigating. He was
still forced to remind himself
that she was underage. Let's face it: Hal Jordan is a pedophile.
Now, as one of our readers pointed out, "Technically pedophilia only
applies to chasing after pre-pubescent kids. But there's definitely
something skeevy about Hal Jordan. Like a 40-year-old guy who stands
across the street from the high school and stares every day when class
lets out." So yes, legally he's not a pedophile, he's more like a
statutory rapist, or a plain ol' sex offender. But "pedo" is just a
funnier word.
And that, friends, is why we say "Hal Jordan is a Pedophile."
(Bet you that Superman fans never have to get into debates about the
difference between pedophilia and statutory rape, and which one their
hero enjoys.)
