Arisia was one of many extra-terrestrial Green Lanterns introduced over the years, but getting her right is pretty tricky, because she underwent some really uncomfortable stories. Originally, she was a teenage girl from the sector beside Hal's, and that it. She had a big brother/little sister relationship with Hal, and it was just fine.
We've actually totally embraced that part of her story, because Hal is one of the few characters in the original Justice League to not have a sidekick, and Arisia actually totally fits that role. She wasn't on Earth where she could join the Teen Titans because she had her own sector to patrol, but still, she was there. We even made her the exact same age as Dick Grayson and his contemporaries in the original Titans.
When Len Wein took over the book, he started playing up Arisia's schoolgirl crush on Hal, which was a little weird, but it got really uncomfortable during Steve Englehart's run. The website Comic Book Resources covered this pretty thoroughly, but the short version is that Arisia aged herself to adulthood and Hal started sleeping with her.
Englehart did his best to make this okay, but.... yea... it wasn't okay. Comics are full of old stories that don't really hold up when you go back and read them today, but I have a hard time imagining this ever being anything but gross.
Part of Hal's character has always been that he's a narcissist, and having him start dating his former protege & sidekick once she grows up certainly feeds into that, but for the love of god, we can wait until she's an adult before we have that happen. It's already pretty creepy. It's an early glimpse into the character of a man that could one day become Parallax.
Arisia's time after the fall of the Lantern Corp was actually pretty cool, having all sorts of adventures with Guy Gardner where she gets to be quite a badass, but eventually she was one of the classic Lantern characters to return to the Corp once it restarted.
We do largely the same thing, but in addition to having her rejoin the Corp, we also made her part of Adam Strange's Omega Men. The team is already incredibly powerful, and having an awesome Green Lantern like Arisia makes them even cooler.
