- This article is about Luigi's appearance in Super Smash Bros.. For the character in other contexts, see Luigi.
Luigi (ルイージ, Ruīji) appears in Super Smash Bros. as one of the four unlockable characters. Throughout Nintendo's history, he has always lived in Mario's shadow. Super Smash Bros. is no exception, as Luigi is often considered as just an inferior clone of Mario. Regardless, Luigi should not be underestimated, as his combos, although less varied and versatile than Mario's, can be followed by his devastating Super Jump Punch attack.
He is currently 10th tied with Link on the tier list for his floatiness and overall awkward physics, despite some devastating combos involving his Super Jump Punch.
 How to unlock Luigi
To unlock Luigi in Super Smash Bros., the player should successfully complete Break the Targets with each of the eight original characters. The player will then have to face Luigi with the character he or she used most recently in a 1-stock match on Peach's Castle in order to unlock him. Should the player fail to defeat Luigi, he or she can simply return to the Break the Targets menu and complete just one of the levels as any character in order to fight him once again.
Luigi is notable for being the only full clone in Smash 64. Many of his attacks are similar to Mario's, although there are differences. Luigi's main problem is his terrible physics - a combination of slow dashing speed, very slow air speed, high traction, and low falling speed gives him very poor mobility and big trouble approaching, even with a projectile in his Fireballs. He also has a high short hop and short range.
Luigi has a relatively good recovery - despite being on the more predictable side, his jumps are high and Super Jump Punch travels a fairly high distance, with Luigi Cyclone being an additional recovery option (though it requires very fast button mashing to give distance). Luigi's Fire Jump Punch is a very powerful KO move, and it can be combo'd into with a down aerial or forward aerial. Despite this, however, Luigi generally cannot combo well due to his very low air speed. His down aerial is his main combo move, but being a drill, it can be DI'd out of, hindering its effectiveness. The Luigi Cyclone (his down special move) can pseudo-spike most characters as an edgeguarding technique, but this is ineffective against characters who can recover from it quickly, including Pikachu, Mario, and other Luigis. Luigi has the highest initial jump in the game, which can be a good thing on stages like Hyrule, but it gives him a high short hop, which further hinders his combo ability, especially since it's also rather slow. Luigi lacks a particularly powerful KO move outside his Fire Jump Punch, limiting his KO options.
Luigi overall has poor matchups, being heavily countered by Pikachu and having a 40-60 matchup against six characters in the game. He does however have an even matchup against Yoshi and Donkey Kong, and he also does well against Samus and Jigglypuff, hard countering the latter due to his Fire Jump Punch.

- It should be noted that Luigi is the only "clone" character in Super Smash Bros.. He shares almost all of his moves with Mario, albeit with a few minor differences.
|Neutral attack 1
|Neutral attack 2
|Neutral attack 3
||A kick. This move is a natural combo. Taken directly from Mario's attack combo in Super Mario 64.
||Decent spacer and KOs at very high damage percentages.
||Does an uppercut, and has many of the same uses as Mario's uppercut in that it is a good combo starter, chains into itself, and can KO at high percentages.
||Low knockback and range. An easily countered move unless there's a good strategy behind it.
||12% if all hits connect
||Six hits, 2% per hit. The last hit has no knockback, and coupled with some ending lag, this move is easily punished.
||The exact same as Mario's; winds up for a second and punches with an enlarged fist. Powerful, but the weakest forward smash in the game. Using it in a short step will cause Luigi to slide forward a short distance.
||Lunges head upwards in an arc. Decent knockback.
||Faster than Mario's, and good damage and power.
||Does a sex kick, which gets weaker over time.
||Spin kick. Luigi sticks his feet out in front, his body aimed forward with them, and spins.
||Thrusts his feet back and flips.
||Great for juggling or KO-ing, depending on what angle the foe is hit on.
||24% if all hits connect
||Drill kick, 8 hits, 3% per hit. Like Mario's, this is a spike. Last hit does not have knockback.
||Same as Mario, swings foe once and tosses them in front with good power.
||Swings three times and tosses foe behind with excellent KO power, a throw from Super Mario 64.
|Floor attack (front)
||Leg sweeps and gets up, similar to his d-smash.
|Floor attack (back)
||Leg sweeps and gets up, similar to his d-smash.
|Edge attack (fast)
||Gets up and somersaults.
|Edge attack (slow)
||Slowly gets up and kicks.
||Throws a green fireball as a projectile. Unlike Mario's, it is not affected by gravity and travels forward perfectly straight, even in midair.
||Super Jump Punch
||25% (sweetspot), 1% (sourspot)
||Does a jumping uppercut. Although it is visually similar to Mario's, it functions very differently. If Luigi is right next to the opponent and does it, it will become a Fire Jump Punch, a move with high damage and powerful knockback, able to KO Jigglypuff at rather low percentages. It can also be combo'd into from a down aerial, or a forward aerial hitting with the weak hitbox (on Luigi's feet). Otherwise, the sour spot deals almost no damage and knockback, leaving Luigi extremely vulnerable. Luigi has some devastating combos involving the Fire Jump Punch. Like Mario's, it is a good recovery move.
||A spinning attack that resembles the Spin Jump from Super Mario World. Unlike Mario's, it only hits once. If the B button is pressed repeatedly in midair, Luigi will rise upwards. It has vertical KO power at percentages under 100% when used close to the upper blast line, and can be used as a followup to an up aerial.
- Taunt: Puts his arms by his sides and slightly behind him, lowers his head and kicks with his left foot. If the foot connects with an opponent it deals 1% damage with set knockback and stun. This is the only damaging taunt in Super Smash Bros.. It is possible for a team of two Luigis to perform an infinite combo on lighter characters such as Jigglypuff using nothing but their taunts.

 Cyclone Recovery
Luigi can gain vertical distance during the Luigi Cyclone if the B button is mashed often enough during the attack animation.
 Mario Bros. Pseudo Spike
Both Mario and Luigi can "spike" an opponent by repeatedly using their down aerials on the opponent when off the edge and then taking advantage of their huge vertical recoveries to get back to the stage. This does not work against Pikachu, who has a much longer and faster vertical recovery than either Mario or Luigi.
Though often hidden in his older brother Mario's shadow, Luigi is, in reality, very popular. Taller than Mario, Luigi also jumps higher. Although he didn't appear in Super Mario 64, in Mario Kart 64 he performed to the best of his ability. For one who seems to always seems to be in the background, he has many fans who eagerly await his appearance.
Luigi's changeable clothing in SSB
- Oddly, Luigi appears in Super Smash Bros. twice (not including the introduction sequence, which features all twelve characters) before being unlocked, in the "How to Play" sequence, and in a 1P Game match in which the player and a randomly chosen ally must defeat Luigi and Mario on Peach's Castle. This makes him the only unlockable character to appear in the 1P Game.
- Luigi is the only unlockable character in Super Smash Bros. who is unlocked without playing the 1P Game.
- Luigi takes his appearance from Super Mario World, having purple overalls rather than dark blue. This is not true to the artwork however.
