The costume.
Something about that feathered helmet the open chest and the wings just looks so COOL! I think once they start delving too much into the reincarnation and the ultra violence, upping his strength levels and above all 'modernizing' the costume.... I like him less and less. But old school JSA/Satellite era Hawkman… Carter OR Katar, he was always a favorite mid/low tier hero of mine.
