So with DLC characters confirmed to be happening, i'm curious who people want to see added to the game that didn't make the initial roster. We're already getting Mewtwo so that base is covered, but there's plenty of other characters in the Nintendo-verse, and we have some leeway with third parties such as Sega, Bandai-Namco and Capcom (and in some respect Ubisoft and Konami).
There's two characters I really want to see hit Smash Bros. in some form of DLC. I really think if they put a little effort into it, Tails would make an excellent character. He has a defined playstyle and form of combat in the first (Genesis) and second generations (Dreamcast/GBA) of Sonic titles so I really think he could work. Have him be an above-average speed character like Mario or Pit. Give him three air-jumps like Pit or Charizard. Many of his attacks can incorporate tail attacks like he uses in Sonic Adventure and Sonic Advance (his running attack could be the spinning tail item from Adventure). For specials, his Down-B should still be the spindash, his Up-B would be free-flight, similar to ROB or Brawl's Pit. Standard and Side specials could be abilities from his spinoff game Tails' Adventure, such as a Ring Bomb attack or other gadget-based moves. His Final Smash could summon the Tornado-2 for a bombing run. The potential is there and I would love to see Tails get some more spotlight time; it feels like Sega keeps writing him off to the sidelines for everything. Amy too.
The second character, and I mentioned this in the Club Nintendo post-play survey: Mike from StarTropics. StarTropics is the only Nintendo franchise that is not acknowledged by Smash Bros in any way beyond the system chronicle in Brawl. We get mention of all these other franchises that Americans have never heard of (or at least not by their Japanese names, such as Mother or Panel de Pon, Earthbound and Tetris Attack/Puzzle League respectively) but somewhere along the line StarTropics fell off the radar, despite having two late NES titles that were actually pretty fun (they played like Zelda, top-down dungeon exploring with some awkward jumping). While I've never finished either game, I still feel that Startropics should be in Smash Bros somewhere and having Mike as a playable character would be great in that respect. On doing some research, it's possible that he's not included nor is the series mentioned because StarTropics has never been released in Japan; Japanese audiences may not know about it and given that Japan is the main marketing target...
Some other potential DLC characters I would like to see:
Magnus (Kid Icarus Uprising) as a fully playable character and not just an assist trophy; honestly I'm surprised this didn't happen.
Rayman (Rayman), he has a
trophy in the Wii U version for some reason despite no Ubisoft content in the game whatsoever, so why not?
Ivysaur (Pokemon R/B/Y/G), Charizard got his own character, why not Ivysaur? Or Squirtle for that matter. I liked playing as Ivysaur.
Geno (Super Mario RPG), everyone wants him. If Nintendo could negotiate the rights with Square to bring him back that would be awesome.
Black Mage (Final Fantasy 1), since we're on the subject of Square, a generic Black Mage would be pretty cool to play as.
