Friedrich der Große is a powerful battleship from the Iron Blood faction in Azur Lane, depicted as Bismarck's right-hand woman and a maternal figure to the Iron Blood shipgirls. She is a strategic leader who undertakes covert missions, manipulates alliances against Sirens and rivals, and commands with iron will. Known for her commanding presence, she builds her own fleet, cooperates temporarily with Azur Lane, and pursues grand plans for dominance, often leaving cryptic advice.
