The answer is yes: they’re really twins! Remember, although they are twins, they are not the same. In fact, Mario is played as the older of the two brothers (he’s bigger and slightly shorter), while Luigi is younger, taller and leaner. They also have different looks that add something to who they are as characters.
Mario acts as this brave, reliable section chief, who’s always out in front; but Luigi is straight man instead. He's also something of a coward but will always come through when the chips are down. This twin dynamic is one of the many charms of this series.
That's right, according to widely spread Nintendo information, Mario and Luigi are twins. In harmony with their differing personalities in the plays. Mario, billed as the elder, is shorter, more self-assured and stronger on the take-up of work.
Luigi is the slightly younger twin who is taller and has a bit touchy nature, but very brave. Only when motivated like this does he show his courage. It is also necessary to point out that in the 'Yoshi's Island' series, Baby Mario and Baby Luigi appeared side by side, strengthening the tale of the twins.
They certainly are! Mario and Luigi, the dynamic duo you know from 'Super Mario', are twins. But they're not identical, just fraternal.
Absolutely. Mario and Luigi are twins, and from "Super Mario" the most beloved of all brothers. While Mario is shorter than the others – he is a brave and go-getting person.
Luigi, on the other hand, although a bit scared in life itself, always comes through when you need him most. By contrast, Luigi's towering height and lean form make him instantly different from his brother. Yes, they are twins, just a bit different.
