Nintendo mascots Mario and Luigi possibly have a brother we’ve never heard about. In an interview with Geoff Keighley on GT.TV, Nintendo designer and Super Mario creator Shigeru Miyamoto teased that when Mario is in need of a third brother, the gaming giant may create one for him. Would you like a third Mario brother to be introduced, or would you rather a sister for the mustachioed brothers?

“I don’t know what types of games I’m going to make in the future… Perhaps there will come a day when Mario needs a third brother, and so at that point maybe we’ll create him.” -Shigeru Miyamoto
