25-Star General, and Captain of the D.O.O.P. starship 'Nimbus' - at least he was, before that fateful error - that clerical error that cashiered his commission and dropped him back on Earth!  Of course it was an error - it had to be.

Removed from his post and [shudder] defrocked, Zapp wanders Paragon City. He's steadfast in the face of all evidence, committed in his self-righteous manliness. And he's certain that no matter the challenge, he will rise above it all and regain his former rank and glory. For there can be no doubt that the clerical error will be reversed, and he will command his ship again. Zapp was born to lead, just look at that chin!
