Couzin Ed was host of the station V-Rock until 1986, when he was replaced by his intern Lazlow, because Lazlow would accept lesser pay. He was named after Eddie the 'Ead, the mascot for the band Iron Maiden.
In GTA: Vice City he phoned in to V-Rock, mentioning that he now works as a bus driver, and that his wife is angry with him for not making enough money, as well as attacking Lazlow, claiming that he didn't know anything about rock and roll. It is unknown what happened to him afterwards. It is noteworthy that Ed has a different voice between Grand Theft Auto: Vice City Stories and Grand Theft Auto: Vice City, although this could be because he used a radio voice during his time as a DJ.
