Bowman

Bowman initially gained Shin's dislike by shamelessly trying to borrow money from his fellow pilots so that he could pay the penalty for turning down a mission he was too scared to go on. Eventually he goes and returns only to brag about his kill record for that mission, ignoring the fact that it was at the cost of his wingman who got killed watching Bowman's back. Bowman appears in the manga, the Eclipse comic and the OAV although the OAV does not explore his character. (Source: Wikipedia)
