Gohan

One of the most important character in DBZ/BGT (dubs) and they can't even get a voice for him that sounds like a child. Even Dende who is a minor character in DragonBallZ has a better voice actor. In season 1-3 Gohan and Gokus voice was the same and even with the season 4 improvements Gohan's voice still sucks.

Ox-King

One of the stupid as hell Canadians Gen likes to hire for voice acting. This is not only the worst voice actor on DBZ but on television. The irony of the situation is Ox-Kings voice was great in seasons 1-2 but not in season 4.

King Kai

King Kai is a prime example of Funimations inability to translate characters properly. Originaly King Kai was a wise old grand father with a corny sense of humor not a retarded who stutters and slur his speech.

Korin

The raspy deep dubbed voice of Korin is a prime example ofcharacter misinterpretations.

Frieza

What the voice casters were thinking: Who should we hire for an all powerful, ruthless, egomanic, evil, alien? I know! Lets hire good 'ol grandma. Who ever deiced to go with a femine voice for Frieza should be castrated.

Kami

What kind of sick company would hire a young-sounding voice for a clearly old alien?
