It's weird to look back on how controversial a Smash pick Pac-Man once was. Of all the third parties who have ever gotten in Smash, Pac-Man is the only one there's literally no downsides to including on paper.
- Sonic's reputation was taking a hit during Brawl's times (and even Melee's to a lesser extent)
- Snake contrasts the world of Smash a little too much and has controversial themes to his games
- Mega Man is only really popular in locations where the NES was popular
- Ryu (and the other FGC characters) run the risk of being too technical
- Cloud and Sephiroth could isolate the console war Ninty fanboys of the 90s
- Bayonetta
- Simon and Richter's ties to real religion and historic literature could be out of place
- Joker comes from a highly controversial and arguably overexposed game with an extremely polarising tone and aesthetic
- Hero has a weird history in localisation that would make it pretty hard for Smash-spawned Western fans to seek out earlier titles.
- Banjo has a notoriously hungry yet picky fanbase who may expect any future Xbox Banio outings to get ported to Switch based on a Smash cameo
- Steve could isolate older fans and has a creator with a history of very unkind remarks to say the least.
