Fowler Birdie is the former Supreme Commander of S.P.D.. He is first introduced in the episode "Dismissed", where he relieved Commander Cruger of his duties when Cruger refused to cater his strategy to Birdie's liking. He took control of Earth's S.P.D. until he was rescued by Cruger against Gruumm. Birdie appears in the final S.P.D. episode where he was among the S.P.D. reinforcements to assist in the final battle against the Troobians, apparently having decided to go into battle himself.
