To me, Apart from his Smash, in Brawl Ganondorf is just a dark clone of Captain Falcon.

64 : Didn't played.
Melee : Pichu because he is weaker than Pikachu and he hurts himself with almost every attacks.
Brawl : I hate Olimar because he sucks without his pikmin and he can spam pikmin throw like hell.

By the way, I agree with epic-san about Ganondorf, he is an awesome character and the only character that can win against my brother's Pikachu.

I suppose I'd go with Ice Climbers. Sure, they can use teamwork and everything, but I've tried to play as them and they just couldn't work for me. I tried All-Star with them - I had to use a Continue 6 times!!!

Ganondorf. Seriously, I just find him extremely slow and sluggish.

I would say snake. He was proven to be made a joke character, except in Project M. He is funny, but he just cant be good

I'm honestly surprised at some of the answers people are giving, though I can understand some of the reasons behind them.

Ganondorf is indeed slow, but if you can get the timing down on his moves, and be patient, he is surprisingly decent.

ROB is all range, that's just where his strength lies, the problem is that they take time to max out their damage, also kinda slow overall.

If you don't like pokemon then it's easy to see why you wouldn't like any of the ones they added. Pikachu isn't so much a bad character as he is overpowered one.

Sonic, oh Sonic. It's sad because he could have been a great character. Don't get me wrong, you can definitely get into a flow with him, but unless you've mastered him then he just isn't someone you pick to win. Very few of his moves have the sending power that they should, so it's difficult to finish someone off with him. I don't play with smash balls either (because they are cheap and stupid) so his one redeeming quality never comes into play. (I think Nintendo did this as a jab at Sega for all those years of competition, talk about a sore winner...)

Snake is hard to use, no joke. A real person in a cartoony environment, what do you expect? besides the fact that he jumps like a lead balloon and half of his explosives can also hurt you, his movements just seem out of place. The trick is not to play him like you're trying to play Brawl, try to play him like a normal guy.

Olimar has one simple rule: No Pikmen, No power. The point is not to let him get to that point. As long as you have both feet on the ground it only takes one button (B) to make more, and there is an infinite amount (like Peach's veggies or Dee Dee Dee'd minions), not to mention you can recall your Pikmen at any time. He just takes practice, Olimar can be really annoying if you know how to use him.

Alright, I think I defended the underdogs enough, now to build up some hate!

First, Lucas! Not because he is a bad character, if anything they made him too good. Why make a clone that is is hands down better than the original?! his moves barely have any difference between his and Ness, yet somehow they gave Lucas better standard attacks. It annoys the crap out of me...

Next, Falco. I hate this bird, everything about him is annoying. Once again, why is he better than the original? while I give them points for originality on the reflector it does not make up for the fact that he is a slightly stronger clone of Fox (the star of the franchise!). But, by far, his B move is the worst. Not only does it have an obscene range, it stuns you EVERY SINGLE TIME, should you be unfortunate enough to be near the ledge when getting hit by it then you will fall to your doom.

Lucario! Not a bad character, in fact his moves are pretty nice, but why trade him for Mewtwo? yes, his moves were wonky, but it actually took some skill to use him. Lucario was built for newbies, his passive ability makes all of his attacks hit more frequently and do more damage when he takes damage himself. Half the time you don't win because you are more skilled than another player, only because of the character you were using, and that just isn't fun to me.

Pit! while we're on the not of newby, annoying characters, Pit is the definition of cheap. Lots of jumps (including a long Up + B), two spammy moves (arrows that cross the screen and can arc, plus that stupid spin move that ALSO reflects), a reflector shield, and lots of quick and powerful normal attacks. Aside from all that, could you have picked a more obscure title to bring back out of nowhere? (Seriously, how many of you actually played Kid Icarus?)

Peach, for one simple reason, she can float in the air FOREVER. I hate fighting against players that just hang up in the air, like delaying the inevitable is some kind of viable tactic. A word of advice: what goes up must come down, and when you do I'm sending you back in a very painful manor...

Finally, my most despised and deeply hated Smash Bros character, and I can't believe I didn't see more of this in the thread. Who else but JIGGLYPUFF, JIGGLYPUFF, MOTHERF***ING JIGGLYPUFF!!! It is the epitome of obnoxious! Bright pink, sickeningly cute, and extremely annoying! Never mind the fact that most of it's moves are utterly useless, the fact of the matter is that they had over 250 of the little buggers to choose from (excluding the ones the already had selected) since Melee was released. So why, oh why, did they stick us with Jigglypuff?! Even when there were only 150 (minus Pikachu) there were plenty of other choices that would have been much better (The Pokemon Trainer was an interesting idea and should have been introduced much sooner. Also, if you're going to pick a cute pokemon for a fighting game then at least choose one that is likable, Clefairy would have made an AWESOME addition to Smash Bros.)

Game and watch is the worst i hate me so much.

I'd say that Ganon is the worst he's just too slow.

I don't think I really hate any character, but I do greatly dislike some.

Biggest thing is Meta Knight; people can make him the cheapest little thing in the world. I hear the only way you stand a chance with excellent MK players is Diddy or Yoshi, but I have not been in touch with what the word is on tiers and such lately.

Excluding what I think is cheap, I think Wario is my worst; I just can't get in a rhythm with him. At least with Link and Ganondworf, I can create some sort of flow with them, but Wario is just so clumsy in my hands. I can be sort of decent, get some hits in, but when it comes to sending someone off, I have a hard time getting that good hit in.

It's funny, because I personally main Peach, and she has a hard time KO'ing, but I found her rhythm pretty easy.

the worst character in super smash bros to me would have to be yoshi because you can basically kill him in one hit its kinda pointless to even battle him because its just too easy.

My least favorite character is Game & Watch... he's just stupid :x

I think everyone has it's ups and downs I suck at so many of them while my friend plays them very well. I always play Toon link for some reason, my fav.

Jigglypuff and Mr.Game and Watch because they are easy to knock off stage due to their light weight. Zangoose would be a better normal type to introduce to Brawl than Jigglypuff.

Haven't played Melee, but for the first one, I can't stand using Fox. Don't know why, but I don't like him. But in Brawl, Mr. Game & Watch is very hard to use. He could be strong, but I think he's too hard to use, and I haven't spent any time trying to master him. And I don't really like Jigglypuff either. Sing is useless, and Rollout isn't that good.

Super Smash Bros 64 - Ness. I just don't like the way he plays in that game.

Super Smash Bros Melee - Pichu/ Young Link - Pichu hurts himself and Young Link is just a slightly faster, weaker, closer ranged version of Link.

Super Smash Bros Brawl - Olimar - I already don't like Pikmin very much, but after I tried playing as Olimar out of sheer curiosity, I hated him.

The worst smash bros character has to be Jigglypuff. He/She is completely useless. It's Final Smash in Brawl was completely unneeded and weak. Not only is Jigglypuff weak, but why is he in EVERY GAME?? It feels like a big slap to the face! They could have added Tails, Bowser Junior, or even Mega Man. But, they instead break my spirit by adding this annoying puffball! 

Hands down the worst character in Super Smash Bros., throughout Melee and over, would be Ganondorf, and in turn the one he is cloned from, Captain Falcon.

His moves take forever, he's slow, and the attacks he does have are over-powered.
