Let's try Mario!
How many characters did you think of before eventually coming to Geno?
Geno's problem isn't a lack of interest or potential. It's that he's essentially a historical footnote in a series with a pantheon of regularly used and beloved characters.
He's overshadowed by several characters in his own series to the point where people can easily be hardcore Mario fans, and never know who Geno is. This is something

Geno's still got a shot, sure. But I'm honestly skeptical of his chances. He's truly unlike the majority of characters in Smash and doesn't have developmental shenanigans to sneak on by like
