Who she is: Antiope
Her power: Antiope possesses superhuman strength and enhanced fighting abilities.
Her story: Antiope is the leader of the Amazon warriors, and sister to Queen Hippolyta. She is responsible for training all the women on Themyscira in combat. She secretly begins training Princess Diana (a.k.a. Wonder Woman) after the girl asks for her help, and then continues her training even after they’re discovered by Hippolyta. When Steve Trevor’s plane crashes off the coast of the island and German soldiers storm the beach, she leads the fight against them. Unfortunately, she’s also killed in the melee, though not before pulling off some pretty badass moves.
