Super Smash Brothers Ultimate - Common thoughts

"One game wonder"

So is Ness, Ice Climbers, Roy, Lucas, Robin, Lucina, Wii Fit Trainer, and Dark Pit. Also if you didn't include franchise spin-offs then Sheik, Cloud, Corrin, Chrom and Daisy would also be included.

I guess that being the star of your single-game franchise is totally comparable to being a major character in one spin-off game in an otherwise gigantic franchise with thousands of characters.
