The Pokemon are loosely based on the anime. It is why we have Jigglypuff, it is why Lucario uses Aura, and it is why Mewtwo talks. So it is definitely plausible. Mewtwo, while being a final boss, is not an antagonist.
Lucario using Aura as means of combat has nothing to do with the movie he's from. That's just a Lucario trait.
As for Mewtwo, he's treated in an antagonistic light within Smash, which can especially be seen in Melee with Event 51. This is very likely due to his characterization within the movie, where he was the antagonist.
As for why not Meowth, perhaps he just doesn't see any point in him?
Jigglypuff is not a good counterpoint for Meowth, as Jigglypuff was an easy add in 64 using pre-existing data from Kirby and served as a joke character designed to be pathetically weak.
Timing also worked in Jigglypuff's favor, too. Had Jigglypuff not been a recurring gag in the anime at that point, it's highly unlikely she would be in Smash Bros.
at all to this day.
And considering it took until
Brawl for even someone like
Charizard to be included when Charizard is one of THE most significant and popular Pokémon in the franchise, do you REALLY want to argue that Meowth hasn't been included over some stupid bias?
It was not dead when he added Ness or Lucas. He had an oppurtunity then, and he avoided it, because of bias.
Because not adding Porky of all characters means he's biased against antagonists.
Despite not being "dead", it was still a very niche series. So niche, that Ness was originally going to be
scrapped in Melee in favor of the Earthbound 64 protagonist before that game got cancelled. So GOOD IDEA! Let's add Porky when Ness HIMSELF was on the chopping block!
And when Lucas was added to the roster, Mother 3 wasn't actually
released yet. It was still in development.
So which makes more sense? Including the protagonist of the soon to be released game, who happened to be the same character who was going to be in Melee in place of Ness initially, or adding a secondary villain from Ness' game?
I believe there is a human form of Andross. I am not literally asking the floating head.
There has never been a "humanoid" Andross in the games outside of brief flashbacks.
Which itself is not grounds for being playable in Smash.
I thought Medusa was the original antagonist. Albeit, it is pretty hilarious that Smash 4 was all about ""relevancy"" and yet they were too relevant. Ha ha ha...
So Sakurai is biased against antagonists because he didn't include Medusa and Hades alongside Palutena and Dark Pit?
As if we needed
more reason for people to ***** about a "Kid Icarus bias" on his part.
Same as Mother, it was not dead in the beginning and Black Shadow replacing Falconforf would be a viable option if Sakurai were not biased, as I stated before.
Or maybe, just maybe....Black Shadow didn't get Ganondorf's moveset because Sakurai didn't want to drastically change
Ganondorf and wanted to keep him as the slow and powerful heavyhitter he was designed as in Melee?
Or maybe he simply doesn't like the idea of just passing off the "scraps" of a character to some other character just for the sake of rebuilding the first character from scratch when time is an issue?
But no, that would make too much
sense. It's obviously just because he has a bias against antagonists!
Most of these characters have plenty more than "just an antagonist." I specifically chose ones that had more. I could list even more antagonists, but I chose to pick the obvious important ones that likely would have made it in if someone else were in charge.
You clearly have no idea how characters get in Smash or how development works if you think even ONE of those characters would have been included solely due to a different director.
EDIT: Yeah, I know I'm getting confrontational.
At this point, I don't care.
If someone makes a bold, irrational claim, has faulty "evidence" for the claim, and tries to
use the claim to argue against an unrelated character, I'm not pulling any punches.
