The playable characters found in the Super Smash Brothers series are full of variety, and the unpopular characters get to mingle with the popular characters. I daresay that certain characters could have only entered Smash as a playable character at one point of time but would otherwise be unfeasible, but their inclusion basically immortalised their place as one of Nintendo's famous characters. Here are some that I can think of:
Lucas: Sakurai admitted that he was included because of a mistaken assumption that MOTHER 3 would be localised, but the unfortunate reality is that it never did, making Lucas a huge outlier as a character who was region-exclusive, more so than Roy since Fire Emblem characters were basically requested to not be removed. I doubt Lucas would have made it in if it would be known that MOTHER 3 won't be localised.
Jigglypuff: As part of the original 12, Jigglypuff is an outlier since unlike the other characters, it is not the main character of a universe nor is it a longlasting popular character. It is believed that Jigglypuff has the fortune of sharing its body type with Kirby, and that it is popular in the anime series at that time, which is why it made it. Given how Jigglypuff isn't a popular Pokemon as time goes by, it's doubtful that it will be included in a future game.
Lucario/Greninja/Incineroar/Pichu: A current-gen Pokemon tends to get included in a Smash game, and these three fit the bill. When Brawl was released Gen 4 was underway, 4 was when Gen 6 was underway, and finally, Ultimate was when Gen 7 was underway. That means we never have a Gen 3 or Gen 5 Pokemon as they were out of range. Instead, new Pokemon tend to come from Gen 1 since it's the most popular generation after all.
Dr. Mario: Basically an echo fighter of Mario, Dr. Mario was made to pad out the roster since making derivative characters are far easier than an original character. Ever since Mario have changes in his moveset, Dr. Mario (as well as other Melee echos) can comfortably remove his echo status just by not changing at all. Given the huge variety of Mario characters, Dr. Mario is an outlier by being a different version of an existing character.
What other characters basically lucked out?
