Luigi (マリオ, Ruīji) is the younger brother of the more-famous Mario, but is still a prominent character. Luigi is always known as "the second one" due to being under the shadow of his older brother. However, Luigi also had his own games where he was the protagonist, such as the well-known Luigi's Mansion series. Luigi has appeared in the Super Smash Bros. series since the first installment, almost always as an unlockable character (except for the previous installment).
Luigi is a surprisingly strong middleweight with very quick attack speed, yet slow mobility and short range. Like Mario, his Fireballs are spammable and help his approach, but Luigi’s travel less distance and are not affected by gravity, which can be good or bad depending on the situation. Luigi's jumps are very high, amongst the longest jumps in the game, which helps his air game.
Luigi's main problems revolve around his unusual mobility and his poor reach. His moves are quick, but short-ranged, so characters that can keep Luigi away with their speed and range fare well.
