It’s no secret that there are instances where ideas and items are scrapped from a game. Super Smash Bros. Brawl had scrapped characters such as Dixie Kong and Mewtwo deep in its beta elements. However, in Super Smash Bros. for Wii U/3DS, there have been a few things revealed here and there, but not yet this.
Through sheer tenacity from a diehard fan, unused textures were discovered in the games. In this revelation, it appears that Dr. Mario was not only slated to have his own stage at some point in development, but the viruses were also revealed to have some sort of role in the game. The jury is out whether it’s as a scrapped assist trophy or a boss character in the Dr. Mario stage, much like Yellow Devil and Ridley.
This makes one start to wonder what exactly were the viruses’ role? Were they going to be a crucial part in the stage or were they too overpowered of an assist trophy? Who knows why the developers scrapped the idea, but it would’ve been interesting to see a Dr. Mario-themed stage.
