I could try to search the old polls, but honestly their results (characters featured very often) were very similar to the ones we could see here or on Reddit, back then (things might have changed recently, I've not lurked on French/European sites yet, since Ultimate's reveal).
That's why I always found these specific polls' results frankly weird compared to what we usually get pretty much everywhere else. Like, what kind of method did they even use? Some universes are bunched together and it makes no sense (Kirby/Metroid/Sonic???), they have different totals that add to more than 100%... And even then, Bayonetta's first place is a slim first place. Their visual on the 2nd poll is also a bit misleading since people could believe Bayonetta got more than 10k votes just for her when it was the total of votes all characters included.
Isaac's good results do make some sense since Golden Sun is very popular in Spain and Latin America, and while I could totally believe Bayonetta might be as popular (and also on Tumblr as you mentioned), ultimately the two polls were made on the exact same site (which is apparently not specialized on Smash, this does matter a little bit sometimes, as Smash Bros focused communities instinctively know relatively better what works and what doesn't) and I have no idea if it's a big site. Finally, I personally tend to stay really cautious because one poll can very well be rigged by bots, we had examples of that on Reddit once if I remember correctly, and it is hard to check.
I'd also find it quite strange if Nintendo/Sakurai/whoever managed the results mixed together Latin America and Europe, but it is a possibility.
I used a lot of words specifically to keep a discourse as balanced and rational as possible.
As I stated before, Nintenderos is a big portal who only focus on Nintendo and is crowded by casuals, so it's a important thing to have a "good results" because we know what they can vote, at least for the spanish part (one of the big cons of Isaac that some people said is he was only known in the Smash sites).
About the first poll, they just wanted to group some franchises to facilitize the search/candidates I guess. To vote, as I could see, you needed to registrate and vote in the website, and, in case you character wasn't in the list, you needed to say it in the thread (
http://www.nintenderos.com/2015/04/...uieres-ver-como-luchador-en-super-smash-bros/ ). Obviously, it could happen some people had two or more accounts, but well, the same happened in the poll when some people voted using different devices and networks.
About the second one, in the picture they said the total amounts of votes, but yeah, it's misleading if you see it with Bayonetta. But well, the website is very click-baiting, so it isn't strange that they did that in purpose.
And I was refering some people could vote in the Spanish poll and the Latinoamerican poll. For example, I remember some guys of King K Rool campaign voted in the japanese poll just for increase their chances and representation of K.Rool in Japan. Maybe Nintendo protected the website not counting the votes which came from other countries, but, well, as you said, it's a possibility.
I want to ask you guys, if Isaac gets in as a playable fighter and you can choose one assist trophy from the Golden Sun series who would it be? I'd go with Jenna using the psynergy 'Fume'
I would choose the four Djinns and only one of them would stay in the stage. The venus Djinn would give the invocator more defense, the mercury one would restore the health, the jupiter one would increase the speed and the jump and the mars one the attack. Yeah, I'm a simple man.
If you search isaac alone it destroys King K Rool
