And here is Aidan Hunter aka Jason Todd, the fallen Robin. He's 24 years old and a CSI for GCPD. He's had a complicated and traumatic life. Please see the above bio/profile. Aidan has little memory of his life before six years ago. There are flashes, nightmares, and the like. But his memories will resurface soon.
He's good at weaponry, martial arts, computers, forensics, languages. A quasi-Jack of All Trades.
