Phoenix Wright (barely any moveset potential imo)
Amy Rose (there are way more iconic Sonic reps out there)
Quote (series is too obscure)
Beat from Jet Set Radio (sorry that one guy who shoehorns him in on every single one of his posts)
Madeline (iconic, but very little moveset potential, and there are better indie options)
Hat Kid (not iconic enough, sorry)
Anyone from Danganropa (Master Chief would fit in better)[/SPOILER]
I can respect your opinions. But i have to point out somethings i noticed about your reasonings.
"Pheonix Wright (barely any moveset potential imo)"
I know that literally everyone has said this in the past. But Pheonix was in Marvel vs Capcom 3, so moveset potential isn't that big of an issue. If Sakurai and the team can get Mr Game and Watch, Wii Fit Trainer, R.O.B, and the motherhecking Dog from Duck Hunt and give them fully functional movesets. I think that they wouldn't have that much of a problem making a moveset for Pheonix."
"Quote (series is too obscure)"
While the series can be classified as semi obscure. Was anyone really talking about Ice Climber or Kid Icarus before they got added to smash? And plus, Quote actually does have a lot of significance to gaming history, being one of the first Indie games to really blow up here in the west. While i would prefer Reimu Hakurei over Quote, i still think Quote has somewhat of a shot. The only issue is if Nintendo even wants to associate with Nicalis after all the stuff they did. I'm not going to go into it here as idk if saying what they did is allowed. But you can look it up for yourself
"Anyone from Danganronpa (Master Chief would fit in better)"
I'm going to have to try to put aside my Danganronpa bias for this one. But i want to first off ask something. What does Master Chief have to do with any of this? You could of compared it to another Visual Novel character, such as Professor Layton.
Secondly, what exactly do you mean by "fit in better"? when has Smash ever cared about a character fitting in? We have characters that use Real Life Fire Arms in the same game as friggin Steve from Minecraft. I don't think they really care if a character fits in or not as long as they are fun. Given how Spike Chunsoft and Nintendo have a great relationship with each other, given how Spike Chunsoft helped develop the Pokemon Mystery Dungeons series. I think it stands to reason that Nintendo could go to them to get a character from them into Smash if they so wanted to. And with how popular of a series Danganronpa is. I think that it could be something they would go for.
