So now that Banjo & Kazooie are in, it doesn't seem like we got a wave of Dixie supporters, even with Steve Mayles saying she's next. Any ideas why?
There are several factors why.
I hope nobody takes this the wrong way because I actually like Dixie Kong and would be cool with her in Smash
1. 3rd Party Characters are the focus
This probably is the biggest reason why she unfortunately hasn't gained much momentum and feel like it's a lost cause.
While it's not guranteed that the remainder of the DLC will be exclusively 3rd Party it sure really looks like it, I honestly believe Sakurai wants to expand the Smash Universe beyond 1st Party Characters, I mean this is "Ultimate" after all and he is pushing for the biggest crossover in video game history and thinks that this is the last time he will do anything this ambitious with the roster.
Some people don't want to hear it, But lets be honest and especially when it comes to DLC, 3rd Party Characters are a bigger deal and make a bigger impact than secondary 1st Party Characters who are overshadow by the main characters already representing the franchise in Smash.
No offense to Dixie Kong, But I'm surprised anyone would think that Nintendo would end their E3 presentation with her reveal even though the DK cinematic was baiting many fans into thinking that, many would be happy and cool with her in Smash, But she isn't a "Showstopper" or "Jaw Dropper" character reveal, That's why Banjo-Kazooie was the "Showstopper" to close out E3. I said it before and I will say it again ,But she should have been revealed before King K. Rool as a Semi-Clone in the middle of the August Direct.
2. Overshadowed by DK, Diddy Kong and King K. Rool
Many don't view her as important or essential as those 3 characters, She is often seen as "Diddy's Sidekick" or the "3rd or 4th wheel" of the DK cast, Many franchises in Smash are represented by the main character (DK), sidekick or secondary character (Diddy) and main antagonist (King K.Rool) some examples also include the Kirby, Star Fox and maybe Metroid I guess and even though Donkey Kong is bigger than all 3 of those franchises, The series unfortunately doesn't get treated like it or gets the respect it deserves.
Yes I know she was in DKC 2 and even though they felt more like a tag team Diddy Kong was viewed as the main character, I mean it is called "Diddy's Kong Quest" after all and while she is the main character in DKC 3 that game is considered the least popular in the Country series despite still being a solid platformer.
3. King K. Rool and Banjo-Kazooie are considered to be more important or a bigger deal and are tired or out of gas from roster speculation.
Donkey Kong was the last big Nintendo franchise in Smash to have yet get it's main antagonist and it didn't help that his last major appearence in that role was in Donkey Kong 64 (1999) which was nearly 20 years ago, Donkey Kong was considered a much bigger deal back then too during it's time with Rareware and King K. Rool and the Kremlings were viewed as the equivalent of Mario and Bowsers Army to their franchise. After her appearance in Tropical Freeze many believe Dixie will be safe for future entries, But many fans felt it was more important and vital to bring back King K.Rool as his comeback in Smash would help bring him back to relevancy and reestablish himself as the main antagonist of the DK franchise since his future was much more murky.
The main reason Banjo-Kazooie are held to such high regard is not just because of their great games on the N64, But the duo were legally 1st Party/ 2nd Party Nintendo Characters during Rareware's time with Nintendo in the N64 era, After Donkey Kong there was no doubt that Banjo-Kazooie franchise was the face of Rareware seeing how DK was still a Nintendo owned creation, They were always seen as a perfect fit for Smash and were considered for Melee, But as we all know the 2002 Microsoft Buyout killed that dream until in recent years Phil Spencer (Head of Microsoft's Xbox Division) was cool with them joining Smash seeing how they have a working partnership with Nintendo and it came at a perfect time right when Smash 4 DLC was happening and Smash Ultimate was announced (2015-2018), That's when their campaign really snowballed and took off and once King K.Rool got it and seeing how there is a lot of overlap between fans of Donkey Kong and Banjo-Kazooie because of their Rareware connection many fans wanted to strike while the iron was hot, Hell I remember last year shortly after King K.Rool got announced the Banjo-Kazooie thread and online in general got a surge of momentum as many crossed over to push for the bear and bird and now that both are in I've only have seen minor support onto other Rareware characters such as Dixie Kong and Conker, I assume many don't see them as important as the other 2. Just look at Youtube, Banjo-Kazooie already has millions of views from their official reveal trailer as many don't see them as just another 3rd Party Character, But more of a long lost Nintendo character returning home.
Smash Roster Speculation is also long and exhausting for some people me included and many don't want to go through a 3rd year of a DLC roster cycle (King K.Rool Year 1) (Banjo-Kazooie Year 2) I only created an account on Smashboards was to rally for Banjo-Kazooie and King K. Rool and will likely leave at the end of the year once the season 1 fighter pass wraps up as I am exausted and already out of gas.
Like I have said before, Personally I would like Dixie Kong in Smash, But I'm not begging on my knees for her like I was for Banjo-Kazooie and King K. Rool and since 3rd Party Characters are seem much more likely I think I would rather take my chances with Crash Bandicoot as he is my most wanted 3rd Party Character after Banjo-Kazooie.
