This papercraft is Hawkgirl (Shayera Hol), a legacy DC Comics character used by female counterparts to the super-hero Hawkman, one of the founding members of the Justice League, and a member of the Thanagarian military, the paper model created by wackywelsh.
She wields a mace and uses Nth Metal technology to fly. Carter Hall's wife Shiera Sanders was the first to use the name during the Golden Age, although Katar Hol's wife Shayera Hol from the planet Thanagar used it during the Silver Age. Kendra Saunders, a reincarnation of Shiera, would also take the name until she was murdered during Blackest Night. The character has been involved with the All-Star Squadron, Birds of Prey, Justice League and Justice Society.
