Smash Master
Whoops.Mystery of the Emblem was a SNES release, so Marth could count for that as well. Roy is from the GBA.
Dude. Stop it. It has been said before that there is no official way of measuring how iconic something is. You do not dictate how "iconic" a character or series is. This list is wrong on so many levels. Considering their recent fame I'd say Shantae, Shovel Knight, etc. are better off than characters like Akira or Banjo (ignoring Banjo's recent Smash announcement; he hasn't had a game in over a decade).I have to mention that assist trophies can be silly heartbreakers when it comes to those who have a potential to be playable. In fact, for them being an assist trophy is worse than not including them in the game at all. On the other hand when it comes to those who shouldn't be playable, being an assist trophy is better than nothing.
Also in my opinion, it's best to have more iconic 3rd party characters get in first.
Here's a list of 3rd party characters from my most iconic estimate to least iconic estimate.
Significantly iconic tier: Sonic, Megaman, Pac-Man, Ryu, Cloud, Simon, Bomberman, Heroes (Dragon Quest), Reimu (Touhou), Banjo, Rayman, Kyo (king of fighters), Akira (Virtura Fighter), Arthur (ghost and goblins), Sora, Ryu Hayabusa, Bill Rizer
Insignificantly iconic tier: Protagonist (persona), Jibanyan, Shantae, Fatal Frame Protagonist, Frisk, Shovel Knight, Quote (cave story), Lilac (freedom planet), Beck (mighty no 9)
So here's the pattern,
Sonic got in before Megaman: matches the pattern. Check
Megaman got in before Pacman: matches the pattern. Check
Pac-Man got in before Ryu: matches the pattern. Check
Ryu got in before Cloud: matches the pattern. Check
Cloud got in before Simon: matches the pattern. Check
Simon got in before Bomberman: matches the pattern. Check
Joker/Ren got in before Bomberman: Wait! somethings wrong! Doesn't match pattern, and doesn't merit to be playable.
Banjo got in before Bomberman: Wait! somethings wrong! Doesn't match pattern, but merits to be playable.
You see above that not only am I unhappy because Joker/Ren got in, but also because he got in before a character who is more iconic than him (who is bomberman), and a character who is more iconic that Joker/Ren became an assist trophy. Which I've already aforementioned.
There is no pattern to how characters are revealed or added to decide how iconic somehting is. Snake was revealed before Sonic, does that make him more iconic? Bayo got in before Simon, does that make her more iconic? Answer this honestly.
