A while after we finally got into Teen Titans (a little over a year ago), we actually did compare Titans to the Posse we had in college. It was after the Posse dissolved, but Athena was still in "Oh! Group of five! Who would be whom?" mode. She decided I would be Robin, because I was the instigator for a lot of what we did, and she would be Cyborg because he was the second-in-command who also played video games a lot. Her being Cyborg also had to do with how she got along with Sanzo, who, ironically, would be Beast Boy. Since Cyborg and Beast Boy play video games together a lot and stuff. It made sense at the time. And Sanzo really does match Beast Boy very well, as indicated by her results of the "Which Teen Titan would you be?" quiz.
Our Kougaiji would be Raven, because she was the one who seemed to distance herself from everyone else, except in the case of Sanzo, and she and Sanzo got along kind of the same as Raven and Beast Boy, though Kougaiji had a tendency to be a lot more accommodating of Sanzo. That left Gojyo as Starfire, which I guess works in that Starfire spends more time with Raven than the other Titans do. We didn't really have a Starfire. I wonder if that was our problem.
