Lightning

Lightning (also called Lightning Bolt, Thunder Bolt, or Lightning Blast ) is an attack item found in various Mario games. On its use, it summons a powerful lightning bolt from the sky, usually shrinking opponents.

Mario Kart series
In the Mario Kart series, Lightning is an extremely powerful item that racers usually receive when they are in (or near) last place in a race. When used, Lightning will temporarily shrink all the other racers, making them slower and weaker, in addition to making them spin out and drop their items. It also temporarily makes the racers' voices high-pitched and sped up until being back to normal or getting squashed. It is also the emblem for the Lightning Cup.

In Mario Kart 64, Mario Kart: Super Circuit, and Mario Kart: Double Dash!!, when Lightning is used, a sound like that of a tiny alarm is heard during its effect. In Super Mario Kart that sound is only heard when the Lightning is launched, and in Mario Kart DS onwards, the music in the race is affected when the player is hit by it. In Mario Kart 7, the extra beat that plays in 1st place goes out of sync with the music for a few seconds after the attack. Lightning's effect can be avoided if a racer has a Mega Mushroom, Star, Boo, or Bullet Bill item activated when the bolt strikes, or if they are flying through the air after being shot out of a cannon in all games prior to Mario Kart 7 or are frozen by an Ice Flower in Mario Kart Tour.

Super Mario Kart
In Super Mario Kart, if any shrunken racers are driven over, they will be squashed and unable to move for a few seconds. While shrunk, the character's weight is equal to other shrunken players. This game's iteration of Lightning has a duration that is approximately twice as long as that of all future games. This item can be obtained if the player is in 5th place or lower for most tracks and 2nd or lower for Bowser Castle and Rainbow Road tracks, but overall is the rarest item in the game.

Mario Kart 64
The Thunder Bolt returns in Mario Kart 64, behaving the same as in Super Mario Kart. While shrunk, racers cannot use items in their Item Windows, but they can use items they have deployed. However, if two shrunken racers run into each other, they will both crush each other. A racer can obtain a Thunder Bolt if they are anywhere from second to eighth place.

In the Virtual Console version, the flash from the Thunder Bolt has been toned down due to the possibilities of players getting seizures from it in the original version.

Mario Kart: Super Circuit
Lightning returns again in Mario Kart: Super Circuit, behaving like in Super Mario Kart, though shrunken racers now spin in place if they come in contact with a normal-sized racer. The duration of the item is the shortest in the series, lasting six seconds. Princess Peach, Wario, and Bowser are the only three CPUs that are able to obtain the item.

Mario Kart: Double Dash!!
In Mario Kart: Double Dash!!, Lightning can also scatter racers' items across the road when used. However, the item does not affect racers that are currently indisposed (such as having just been hit by another item, or having fallen over a cliff). Also, unlike in Super Mario Kart, Mario Kart 64, and Mario Kart: Super Circuit, shrunken racers will not get squished if they ram into normal sized racers. However, tiny karts will be easy to push around, even by the Bullet Blaster, which is the lightest kart in the game. Lightning can be dropped on the road after getting hit by something that causes racers to lose their items (e.g. Freezies). However, the Lightning will only stay on the road for a few seconds.

Mario Kart DS
In Mario Kart DS, the effect of being hit by Lightning wears off much faster depending on the rank that the racer is in. For example, someone hit by one while in seventh place will return to normal size almost immediately, while the one in first place will remain shrunk for up to seven seconds. Also, racers who get hit by other items can still be affected by this item. This item can be obtained if the racer is anywhere from 6th to 8th place, with CPUs only being able to obtain it in 8th place.

Mario Kart Wii
In Mario Kart Wii, as in Mario Kart DS, the effect of Lightning lasts more briefly the lower the rank the racer is in, and even if hit by other items, they will still be affected by it. If the racers are under the effects of a Mega Mushroom, they will shrink back to normal size immediately and will not spin out or lose their items. In Battle Mode, unlike other items, Lightning does not take away a balloon or coins. This item can be obtained if the racer is anywhere from 9th to 12th place, with CPUs only being able to obtain it in 12th place. The best chance of getting this item is in 12th place, with a 22.5 percent (9 out of 40) chance of getting it in said position. There is also the Thunder Cloud, which gives the recipient a speed boost prior to striking them with lightning. It is one of six items wherein only one can be in play at a time (the other five being the Thunder Cloud, Spiny Shell, Bullet Bill, POW Block, and Blooper), is one of four items with a cooldown timer for the first few seconds of a race (the other three being the Spiny Shell, POW Block, and Blooper), and is one of three items with a cooldown timer between uses (the other two being the POW Block and Blooper). Lightning is unobtainable for the first thirty seconds of a race, and once a Lightning is used, thirty seconds must elapse before another Lightning is obtainable.

Mario Kart 7
In Mario Kart 7, as in Mario Kart DS and Mario Kart Wii, the effect of being shocked by Lightning will be determined on the level rank the racer is in, from last place having decreased time and first place being shrunk for longer. As before, the music of track will be altered, and even if hit by another item, the racer will still be shrunk. Any racers that are shrunk will also be squished if run over by normal sized racers, an effect returning from Super Mario Kart, Mario Kart 64, and Mario Kart: Super Circuit. Unlike in Mario Kart Wii, when a driver is shot out of a cannon, the shrinking effect will still happen and the driver will fall while gliding in midair. Additionally, up to three racers can hold a Lightning Bolt at a time, potentially unleashing two or three lightning attacks at once. This item can be obtained if the racer is in 7th or 8th place, with CPUs only being able to obtain it in 8th place.

Mario Kart 8 / Mario Kart 8 Deluxe
In Mario Kart 8 and Mario Kart 8 Deluxe, the effect of this item is very similar to its effect in Mario Kart 7. In these games however, when a character is shrunken, the loss of speed makes it more difficult for the racer to perform tricks and to drift. Unlike in previous Mario Kart games, when a racer is hit with Lightning, they will lose the item they are holding even if they are under the effects of a Star (in the original version only). Like the first three games and Mario Kart 7, when a racer is shrunken by Lightning, and another one with the normal size drives on them, they will be squished. Up to three racers can hold Lightning at the same time. As of version 2.2.0, Lightning no longer causes drivers' gliders to close.

Mario Kart Tour
Lightning returns in Mario Kart Tour, with its effect being similar in previous games. Unlike in the previous two games, when a racer is hit with a Lightning while gliding, the glider does not retract. During a Lightning Frenzy, one racer will get struck each time the item is used. When non-Frenzy Lightning is used, interactable objects around the course react to it as they do when hit with an offensive item, but do not give points.

Normally, the player will lose all of their items when hit by Lightning, though if the player is using a Coin Box, Bob-omb Cannon, Mushroom Cannon or Banana Barrels when hit, the item will still be retained.

The following gliders increase the chance of getting Lightning and points for hitting racers with one.

When used, it simultaneously hits all racers besides the user, but unlike in the Mario Kart series, it does not cause shrinking, instead causing racers hit by it to spin out of control and lose some of their Rings.

Super Smash Bros. series
Lightning appears in Super Smash Bros. Brawl, Super Smash Bros. for Nintendo 3DS, Super Smash Bros. for Wii U, and Super Smash Bros. Ultimate as an item. The item usually shrinks all of the player's opponents. However, at times it might backfire and shrink the player who grabbed the item. Lastly, there is a small chance that the item makes the opponents giant-sized, as if they all touched a Super Mushroom. As with the Super Mushroom and Poison Mushroom, figthers only have to touch the item to activate its effects.

Fighters who get shrunk by the Lightning will be set to the exact same size as when they touch a Poison Mushroom (0.5x normal size), but their direct attacks deal 0.7x their normal damage, instead of 0.6x. Also, if players become giant from the Lightning, they will be much bigger than when they grab a Super Mushroom (2.4x normal size, instead of 1.7x), and their direct attacks will deal 1.84x their normal damage.

Additionally, the Lightning item is depicted as a trophy in Super Smash Bros. Brawl, Super Smash Bros. for Nintendo 3DS, and Super Smash Bros. for Wii U, and as a sticker in Super Smash Bros. Brawl. In The Subspace Emissary, the sticker can be used on any fighter to boost their electric attacks by 4 points.

Super Mario-kun
Lightning makes a brief appearance in volume 6 of Super Mario-kun. While struggling, Mario receives this item and then uses it to pulverize Donkey Kong Jr. and win the race. It is also used in another chapter to shrink the Mega Mole that Mario was fighting, giving it the size of a regular Monty Mole.
