Barnabas

Balnab (or Barnabas in the Advance version) is a humanoid robot creation of Dr. Lugae's in Final Fantasy IV.

When Cecil and his friends fight Dr. Lugae, he calls forth Balnab. Balnab was seemingly not created to be smart, and just attacks everything in it's way, including the Doctor. After the party destroys Balnab, Lugae seats himself in the ruined robot, becoming Balnab Z.
