Mach Rider - More like Go K.K. Rider!, no? OK...
Chance: 25% - Aside from the Ice Climbers, this is the only other retro character that is a possibility at being seen in DLC, due to Sakurai's consideration of this character before. However, I also see the problems in getting a character like this to jump. Unlike Bowser Jr., who has a propeller on his vehicle (heck, the Jr./Koopa Clown Car is supposed to stay in the air), a bike isn't easy to make jump, similar to Captain Toad in a way, but at least we've seen Toad's jump before. Also, Wario himself already has a motorcycle, I'm and considering Wario's Bike, Mack Rider seems less likely.
Want: 10% - People have brought up that this character looks "bada**." These kind of characters, as well as "edgy" characters, are generally among the types of characters I dislike the most, although I'm not sure why (what, my profile picture? Yes, Shadow the Hedgehog is among the "edgy" characters that I dislike, but he didn't use to be that way, aka SA2 Shadow wasn't entirely "edgy." Fancy Shadow is my way of coping with the "modern" Shadow). Mach Rider does seem to fit the description, and being a retro game character who hasn't appeared in Smash before, it might be hard to get population interested in him. Also, he looks awfully similar to Captain Falcon, seriously, the two could be brothers.
Predictions: Ugh, didn't we do this one already? Oh, that was Tetra? Wait, aren't these two the same thing?
*prepares for the possible anger of fans*
*sigh*, I feel that I'll just give the same rating I gave Tetra, but as for now, 25%.
Nominations:
Meowth X3
Chibi-Robo X2
*Note, I'm perfectly aware that Tetra and Toon Zelda are technically two completely different things, such as Wind Waker = Tetra and Spirit Tracks = Toon Zelda. However, the two characters are supposed to be one in the same, in a similar manner to Sheik and Zelda I suppose...
