8. Wii Fit Trainer - Mostly cause she's hot and someone drew Rule 34 of me banging her wearing a Villager mask. Don't ask. Long story.
Anyway, top ten
10. Duck Hunt Dog: Really Duck Hunt mostly looks like an "eh" character to me. His specials are interesting, yeah, but other than that his regular moves just feel like they lack an oomph to them. That'll probably change when I play him, but that's what I'm getting right now.
9. Shulk: While the monado arts or whatever looks great, I can't help but shake the feeling that he's unusually slow in attacking from gameplay I've seen. I may be just watching the wrong players, but that's just me. Looks good besides that.
8. Robin: Doing smash attacks in the air was enough for me to like the character. I think the usage of "limited" items is neat. Not much else I have on him/her really.
7. Bowser Jr.: I've never really been a fan of Bowser Jr., but that Clown Car certainly makes up for it. It might be just how differently he moves because of it compared to the rest of the cast. Also I think the mechanic where his clown car takes less damage than normal and Bowser Jr. takes more than normal is a nice touch.
6. Wii Fit Trainer: The straightforwardness of this character is why I think I like her so much. Simple gimmicks, simple playstyle, and a simple theme, go crazy.
5. Rosalina and Luma: Super Mario Galaxy was the first console Mario I played through, so she's more distinct to me than other Mario characters. I've never really clicked with Ice Climbers, but I think this character duo will be great.
4. Pac-Man: Among all the characters of Smash, none really seem to have the...fluidity? that Pac-Man has. There's just something about the way he's animated that makes me want to play him, on top of his moveset also looking really fun.
3. Mii Fighters: I've always been a fan of customizability, and this is where the Mii fighters shine. It's really the varied movesets that get me interested in them.
2. Little Mac: Among the new fighters, he seems downright the most entertaining to play for me. I just play on the ground much more than the air anyway.
1. Palutena: Uprising was one of the few games I completed in the last year, so Palutena was a big character for my time. Since I'm not as familiar with characters like Robin or Shulk, she's the one with the most personality in the new cast to me. Great character, great moveset, great variation, she's the best overall to me.
