What characters do you all support that you never really talk about? The reason behind why you never talk about them can be part of the discussion as well.
Interesting discussion;
Isaac - Golden Sun;
I don't talk too much of him, since I've never really played the games. I don't know his story, nor do I know too much of him. I just know of his AT in Brawl, his mod in Brawl, and Super Smash Flash 2. I think he looks interesting, and have cool powers that would fit in the series, as well as long time fans of both the character and series would get some justice, therefore I support him, but don't talk too much, as I don't feel like I got much to say about him that could lead to a discussion.
Rayman;
I often talk more about Bomberman and Crash Bandicoot as they are the two of three/four 3rd Parties I want. Rayman is the third, but I never talk about him. He just comes third. He had a trophy, and he was part of my childhood, but not much as Crash who is my most wanted third party character, and Bomberman is the one I'm clamoring for because of iconic status, where he would go so well with Pac-Man, Mega Man, Mario and Sonic. Same with Crash. While Rayman get's the backburner for me.
Banjo Kazooie & Krystal from Star Fox;
I'm a bit on and off about them, therefore I placed three/four in the last post regarding wanted 3rd Parties. I've never really played a BK game, but my bestfriend loves the duo, and their series, and therefore he has been talking my head full of him wanting Banjo & Kazooie, and Krystal from Star Fox. Therefore as morale support, I support both Krystal and Banjo Kazooie in spirit of him. I do think that BK could be an interesting duo type, but that Microsoft might limit that chance, even of what PS said. It's Microsoft after all, and I need to see proof before I believe. Krystal on the other hand is also one of the Star Fox characters I like. Still, to me, she comes after Wolf, as I like the character just as much, but his a villain. Krystal would be interesting, and I'd like to see how the Smash team would make her. If either of these would make it, I know my buddy would be really happy. It's the same with me and King K. Rool, he support him just for the fact that I'm dying to see him in the game. I guess you could call it all quite "Rare".
Kamek - Mario Bros/Yoshi Island;
I think Kamek is really cool, and would make the best newcomer for Yoshi. Kamek is important to Bowser, and could fit an interesting fighting style with the magic. I always get the feeling that Yoshi representatives never really get suggested often or considered for a playable role, which is why I never really talk about Kamek. I mention him here and there, but that's quite rare, but it could happen, and I'd love to see Kamek at some point in a playable possition. More Kamek in general.
Meowth - Pokémon;
I've always wanted Meowth as a playable, to rival Pikachu. As I grew up with the anime, and knowing Meowth was a Pokéball Pokémon, I hoped that he might be promoted, just as Little Mac was. He does not have too much support visible, but I know there are people out there that would love the cat n' mice game.
I'm sure there are more, but those are from the top of my head.
