I cannot simply post images of characters and not explain my thoughts on said characters, therefore, I'll continue onwards and explain how I feel about each.
1.)

Most wanted Newcomer after I played Awakening, love her character! She's a strong independent female character who fights with a sword, I mean, we didn't have that until now. Marth clone or not, it doesn't matter. I was going to play her either way, and this just means that I'll have a basic idea of what her moves will be since I've always played Marth (not always as a main, but nevertheless, he was ranked highly and still is). Most likely going to be my main, but still have to play and see.
2.)

My Favorite of the Gen 6 Pokemon with a fight style that looks like he'll be fitting. The speed, projectile water shuriken, good recoveries, teleportation, counter, high priority smash attacks...I could go on for ages. Either way, Greninja is tied for most likely main in my book, and that's without even playing as him! Tied with Sonic and Lucina for main.
3.)

Most unexpected and another character from Awakening I like, the tactical aspects will be fun! A Fire Emblem character with spells and the punishment of items breaking after use. Before I can determine whether I'll main Robin or not, I'll have to play them first.
4.)

A strong female goddess who DOESN'T get kidnapped unlike another female Mario rep. She was a nice surprise and almost like an early Christmas present. Might end up playing her, but idk about maining her just yet.
5.)

Played a lot of Pac-Man as a kid, started with 20th anniversary, went back and played some of the classics, but stopped after Pac Man World 2. Glad Namco-Bandai got their rep in. Probably won't main him, but he'll be fun to play either way.
6.)

Odd as it sounds, Mii's were a pretty cool announcement, they proved me wrong when I said they wouldn't work. I'll probably end up playing swordsman for mine. If they get into competitive play, I might try mine at some point, but who knows. They might not be allowed in competitive events anyways, due to all their customizations.
7.)

Only played Punch Out at a friends house, glad he finally got his spot in the game. He's this high up though since ALL of my friends are wanting to play as him, so I'm glad he's a character they enjoy! Not main material (bad air game is iffy to me), but I'll play him.
8.)

Never really played Mega Man too much, I played Mario and Sonic games evenly (until Sonic Seven Rings and Black Knight came out). So I played Mario>Sonic>Pac-Man>Mega Man. Still glad to see him in though and was hyped to see him make it in. Won't main, but seems really fun.
9.)

Wasn't too much of a fan of Kid Icarus games, but I did like that she showed up to prove me right to my friends (who said she really didn't have much of a chance). She looks interesting to play, but probably won't main her.
10.)

Only played a little bit of Animal Crossing, but I'm glad they finally got a rep instead of just one single freakin stage. I might not main them, but I'll play a little bit with them. This is the last character that I'm glad made it in and made me hyped for SSB4.
11.)

Hated the idea of at first, but now that they're in, eh, I'm neutral with them now. I know one person who'll main them, mainly because he thinks that the idea will throw people off. I'll play a few times as them, but eh, not maining. No hype from their appearance really.
