Speaking of DLC, the only characters I see that would never be anything but DLC only would probably be Pichu and Dr. Mario. And any of the old Team members as bonus clones.(Polygons, etc.) I won't lie, I'd love to be able to play as any of them, and a Primid. Primids themselves were much like the Alloys, fairly close to being almost real fighters. Actually, I would love to be able to use a Primid as my customizable character. Of all the enemies in Brawl, I thought they were neat, as they represented various Items/Regular Fighters like Metal, Giant, Fire Flower, etc.
@ChronoBound: Yeah, I get what you mean. I mean, there's still a lot of characters to go, but the big guns are getting far lower. Although to be fair, enough people want to see Final Fantasy as is. Or a Square Enix character in general, so who knows? Could be Slime. Black Mage. Etc.
