Thunderbolts (also called Lightning or Lightning Bolts) are attack items found in the Mario Kart and Paper Mario series. These special items summon lightning from the sky, causing various effects. In Mario Kart Wii, as in Mario Kart DS, the effect of the thunderbolt lasts more briefly the lower the rank the player is in. Also, players who get hit by other items can still be affected by this item. If the players are under the effects of a Mega Mushroom, they will shrink in size to a normal sized player.
