Barnabas, also known as Balnab, is a humanoid robot creation of Dr. Lugae's in Final Fantasy IV. When Cecil and his friends fight Dr. Lugae, he calls forth Barnabas. Barnabas was seemingly not created to be smart, and only attacks everything in its way, including the Doctor. After the party destroys Barnabas, Lugae seats himself in the ruined robot, becoming Barnabas-Z.
Barnabas is fought before the party engages Dr. Lugae directly.
Barnabas is fought as a boss in the Subterrane with Dr. Lugae. He is fought in the same manner as in the previous game.
Barnabas appears in Final Fantasy Trading Card Game with an Ice-elemental card.
Barnabas was one of the earliest Christian disciples in Jerusalem. He and Paul the Apostle undertook missionary journeys together, defended Gentile converts against the Judaizers and participated in the Council of Jerusalem.
Barnabas's story also harkens to the story of Frankenstein about an eccentric scientist who creates a grotesque creature in an unorthodox scientific experiment.
