Worst character to ever exist in Dragon Ball History...

[ImmaDeker]

but if we include non-canon stuff, then Broly takes this easily

Broli won't be so bad if they didn't made him so lame and his reasons for hating Goku were not so lazy. Broli should have stay dead after Movie 8, Movie 10 and 11 should have been original villains. Bio Broli is one of the worst characters ever in my opinion. He's ugly, lame and unoriginal at the worst. Even as his own character, he still sucks in my opinion. He's just a melting walking dog shit and he dies in the worst cliches in the book.

Bio Broly's a stock Dragonball villain to support a more unique ensemble of protagonists, so I don't really get the problem with him. He serves his purpose. Hell, you'd think people would like Bio Broly more given the joke he's reduced to. He's a parody of himself by that point.

#19 sucks. Dende's a bit of a dweeb too. Babidi is an awesome concept who ends up being really annoying. Extending to non-manga, my list expands exponentially. Slug, #s 13 14 & 15, Broli, Bio-Broli, Dollaki, Rilld, Super #17, Dr Myu, Hatchiyack, Episode of Bardock Bardock, most of the Evil Dragons, 90% of the pre-existing cast as they appear in GT...

Maron, the filler character in the Garlic Junior Saga. She's stupid, and serves no purpose than to be Krillin's girlfriend. I was rooting for Chi-Chi to go Kaioken and whoop her ass.

Also, Babidi. He's the worst villain on the show because he gets others to do his work.

Hatchiyack,

Hatchiyack is a total baller forgot to call her and the entire reason I have any vague interest in the Saiyan mythology as even a concept.

But Maron is sexy... xD Well at least Kurrin got 18 and Babidi is kind of annyoing in that sense but he created the 2nd strongest character in the show(not including BOG)

If this includes filler characters, then I'm choosing the long since forgotten Karoni and Piroshiki . For those that don't remember they were Mr. Satan's pupils during the Cell Games. I shouldn't really have to say anything else...

Personally, I've never been too fond of Yamcha. In Dragon Ball he's okay, I guess, but in Dragon Ball Z, he just gets in everyone's way. I can't think of one thing that Yamcha did in Dragon Ball Z that was the least bit helpful.

he gave us cat loves food: yeah yeah yeah

As horrible a character Broly himself is, I still think he would be the easiest to retcon including why he hated Goku so badly.

[Rockman X]

Gotenks for sure!

don't get me wrong i kinda like goten&trunks.. but gotenks.. i hate that character! not only did he completely ruin buu saga's power levels he is the most annoying character ever and he has so much goddamn power! its almost insulting.

BROLY. Most overrated character of all time.

[Dbzfan94]

The worst part about Broly isn't even why he hates Goku (which is still really bad). The worst part is his fanbase.

I remember people at school loving Broly just based on his look, they hadn't even seen the movies. Such an overrated character.

For me the Broly movies are probably my least favourite.
