Ray Series
Chance - 25% - Despite going dormant, he's actually doing fairly well for a character in his position. He received content in Brawl, and is quite well liked from what I hear. However, with roster space so tight, his best chance is to sneak in under the radar. There is a lot of superior competition. I wouldn't worry about the customizability part, as they can always just use the defaults that you start out with.
Want - 82% - Admittedly, one of my dreams is to have a mecha playable somewhere in Smash Bros. While he may be small, a mecha is a mecha, so yes, please. Heck, based on game mechanics alone, he already has a special set.
Omastar - 0.18% - I'm only expecting him to barely beat out Cole. There's a reason they went extinct, after all.
