Zap Brannigan appeared early in the series. Officially Earth's Greatest Hero, Zap has shown the flag across the known universe. He has also become something of a nemesis to Leela, constantly trying to reproduce his good luck with her on their first encounter
Twenty Five Star Admiral Zap commands the Nimbus, the DOOP flagship. From there he defeated legions of DOOP's enemies including the Killbots , the Pacifists of the Ghandi Nebula, and the Retiree People of the Assisted Living Nebula. He also briefly commanded the Planet Express Ship, but proved not to have the right stuff.
Zap is a 30th century Lothario, with personal quarters aboard the Nimbus that might have come from a 1970s make out van.
