I've always really loved Zarbon. He has a cool design that fits his snobbish attitude and then when he sacrifices his looks to transform into his grotesque true form, to was a good foreshadowing of Frieza.
Also the Ginyu Force, of course. Ginyu himself is great and even the oft-overlooked Guldo is pretty interesting (and DBZ needs more weird bullshit powers like his).
Seems like campaign finance reform is a more pertinent question then.
