For both those who do or do not like Zapp: what would you like to see happen to him in some future episode?
Zapp Branigan has never been a man a subtelty.
He needs big setups, epic plots, to stand in the center of the masses (to get on as many people's nerves as possible).
Modest plots are not his thing (e.g. the two person theater play in IaGGDL, and ZD will probably pursue the same direction). Give him epic plots, bigger responsibility, and even MUCH bigger screw ups.
Also, I would like an episode giving an explanation why he is hailed such a galactic hero. In a "messing up 9 out of 10 missions, but succeeding on such epic scale on mission 10, that this more than equals out the 9 failures".
