Here is a Visual Concept of what Movie Mario would look like in Super Smash Bros! Check out @Awesome3D and his channel! His work is incredible! 🎵Music🎵 Super Mario Bros Movie (Fan Made) - / miguelromomusic
Hello, I'd like to comment that I am one of the people who hates his design. I think it works for the movie, but it doesn't feel like Mario to me. He's got a flattened mustache that just looks wrong to me, a squished nose, fat face, weird hair, weird hat emblem, small hands, weirdly human arms, odd proportions, etc etc. It's less that I dislike the entire design, but rather that a bunch of tiny design differences add up to make a product I dislike. And it's not that he looks more realistic. Mario's dad in the film looks 5x more like game Mario than Mario himself. And Luigi's mustache is composed a lot better than Mario's is, so I know they could've at least made that better. I love how expressive Movie Mario is. His wide range of expressions is what I like most about Movie Mario. But I would've just preferred a more expressive, toned-up game Mario instead. Movie Mario also has a lot of extraneous details in his clothes that would clutter his design in games. His detailed shoes, pointed shirt collar, and overalls chest pocket add a lot of noise to the design that I don't like. I think it's fine to be in the movie design, but I'm still not a fan. I get why people like the movie design, but it just doesn't feel like Mario to me.
I think Smash Mario would work better for the cinematic, since it would make Luigi (or really any other character that also appears in the movie) look out of place if Mario specifically had his movie design.
