Zapp Brannigan is a 25 star General of the DOOP and has been responsible for several successful wars including a triumph of the pacifists of the Ghandi Nebula and his most famous - defeating the Killbots in the octilian system. He is always accompanied on missions by his hapless assistant Kif Kroker. He also is responsible for the directive B10.81, otherwise known as Brannigans law, which prohibits the involvement with undeveloped worlds. But behind all this success and heroism is a wimp who is not very intelligent at all and who uses battle moves such as sending wave after wave of men into battle to be killed, just so the Killbots would reach their preset kill limit. He slept with Leela, a fact which he constantly reminds her of.
On Futurama, he is voiced by Billy West.
