People make it all about repping things, when really this is a video game that needs to play well, and provide a variety of experiences for any one player to enjoy. If it was about representing, and ONLY representing different series, Smash wouldn’t be what it is, plain and simple.
Characters, and the representation of game series and character is absolutely important to Smash. The game is based on using our favorite characters against each other in familiar atmospheres and listening to familiar tunes while doing it. This often gives us a feeling that certain things are added to represent something from the series.
The problem with representing series, ONLY THROUGH CHARACTERS, like Smash character speculation always does, is that it dumbs down characters to only being picked for one reason. Every other reason, like roster diversity in design, ability, and archetype, is that it basically lumps it into, “TRhe Pokémon cast represents Pokémon.” In reality, Pikachu himself doesn’t not represent Mewtwo. Mewtwo represent Mewtwo. Characters are not adding to be a “rep”. They are added because the design team decides, “Hey, a character who does this would be cool”, and they decide on a character.
There’s also added relevance at the time of addition, or popularity, but arguably I would argue the most important factors are what the characters can do and, well, who they are. Just like any single person, it’s not like every character fits any single mold. Everyone is different.
For example, Piranha Plant definitely get in by the standard of, “Series staple, is popular, is a must-add for the Super Mario series”. Piranha Plant very likely was added because it was an oddball addition like Game & Watch and Wii Fit Trainer (oddball as in completely unexpected) but I also provided attributes that allowed it to not only have a unique move-set, but also a unique play style. That’s an important distinction to make.
Basically, I wish the word “rep” would die in a fire. Sure, it’s just a word. But that word just dumbs down what makes some character suggestions/ideas/additions so great. Everyone was just concerned about who would get in for various series, and ignored what certain characters could do. Incineroar, for example, doesn’t even seem like a Pokémon. He’s almost entirely wrestler based, which allows him to show personality and that Heel Wrestler design that is exclusive to Incineroar.
Sure, characters come from series. But characters should be looked at as individuals, rather than just bits of a larger whole.
