That is a hard decision to make because each character has a certain depth to them that anyone who becomes good with them can still make them awesome. My least played characters are Olimar, Jigglypuff, Yoshi, and Lucario. However, my friend really likes Lucario and can even beat me with her from time to time, so she really isn't 'bad'.
hey grondylion i won a tournament with lucas!!! my worst characters is donkee kong im good with jigglypuff and lots of my friends are good with Yoshi EVERYONE THATS MY OPINION
Anyone that claims Jigglypuff is the worst character is naive. Its fine to be bad at using her, but don't say she is horrible because of that. Jigglypuff is all about DI and midair strikes. Yes she is weak, but if you know how to use her you can combo someone very easily. My friend uses his "Wall of pain" and manages to hit me 5 times while I am trying to recover.
wow, I don't think any characters are bad. I manage to beat atleast 1 lvl 9 computer easy with everyone. with jigglypuff (actually the name is purin) i can beat 2 lvl 9 computers with 10 lives while i have 5.
But i'd have to say my best characters are Peach, Yoshi, Capt. Falcon, Charizard, and Toon Link. With each of them I can take on 3 lvl 9 computers easily ( actually quite boring ), the comps will each have 15 lives, while I have 10. that's 45 lives to 10.
If anyone says Yoshi is bad, they just don't know how to use him. I realize he does not have another jump like everyone else, but his single jump goes pretty far and he falls slow. a good move to help him get back on the stage is throwing eggs. you do it quick enough, he almost stops falling and moves towards the stage.
