Super Bombs are items from The Legend of Zelda: A Link to the Past. These powerful bombs are available for purchase in the Bomb Shop in the Dark World, located where Link's House is in the Light World. It is only available once Link has completed the Ice Palace and the Misery Mire dungeons, and reunited the Dwarven Swordsmiths. One Super Bomb costs 100 Rupees. When purchased, it follows Link wherever he goes. However, if Link dashes or jumps off a cliff, the bomb will automatically be left behind with its three second detonation time. The resulting explosion does not damage Link. It is possible to stop the count down and get the bomb to follow Link again if he walks over it before it explodes.
The Super Bomb can be used for not only massive damage (although it's only good for one use, thus eliminating its economical efficiency), but also to blow up a special seal on the Pyramid. Inside is a Mysterious Pond, where Link can speak to a Great Fairy to obtain both the Golden Sword and the Silver Arrows, the latter of which is necessary to defeat Ganon.
Super Bombs appear as an power-up for Bombs. Unlike regular bombs the player character will throw one large Super Bomb instead of several bombs. In the Armies of Ruin scenario, the Great Fairy has her fairy minions take bombs from Link and the Goron Captain to create a large Super Bomb which they drop on the Dark Forces, forcing Wizzro to summon King Dodongo after most of his troops are killed by the bomb.
Link's Great Fairy moveset involves the Great Fairy dropping slightly smaller Super Bombs as one of her combo attacks.
