Do Mario And Luigi Have Another Brother?

Mario and Luigi are like peanut butter and jelly. Peanut butter shows up in a lot of places and is great. Jelly occasionally appears alone (like in donuts), but is most often seen with peanut butter. Together they're fantastic. And quite honestly, there really isn't room for other ingredients. In the case of Mario and Luigi, however, that hasn't stopped people from asking about an additional Mario brother.

Here's the cold, hard truth: there is no third brother to Mario and Luigi. The two are fraternal twins; that might come as a total surprise to some. But in terms of there being a third to potentially tag along and occasionally show up in Super Smash Bros., he does not exist yet.

But if you'd like to imagine a sibling to the two famous plumbers — perhaps a middle child that is often overlooked and unloved by his creators — he might look a lot like Waluigi.

Now, what is causing people to ask about this? What might have planted the idea in the brains of some Super Mario fans that there was a third, hidden brother lurking somewhere in Mario and Luigi's backstory? We think it might have something to do with some news Nintendo's Shigeru Miyamoto made in 2013. In an interview with Geoff Keighley, Miyamoto reportedly stated that he wasn't sure what the future might bring for the games he was making, adding, "Perhaps there will come a day when Mario needs a third brother, and so at that point maybe we'll create him." And on cue, this got spun up into whether a third brother was already present somewhere, totally ignoring the "we'll create him" portion of the quote.

You should probably approach the possibility of Mario and Luigi having another brother in this way: until you see him, he doesn't exist. We know the two brothers have a father because he's made an appearance or two. We're fairly confident the two have a mother because she's been named. But we've yet to encounter clear evidence of there being a third Mario brother. So at this point, if the question is, "Do Mario and Luigi have another brother?" the answer is no.
