Source Gaming Video: Smash Bros. Wii U - Unused data for Robin found

I always find it interesting when new data in an old game is found. Not that Smash Bros. Wii U is super old, but still, it's not fresh off the shelf. I wonder what the original intention was for this data. Hey Nintendo, maybe you could implement it into your Smash Bros. Switch port that you're working on. You're working on that...RIGHT?!
