Thunder

Thunder (サンダー), Thundara (サンダラ), and Thundaga (サンダガ) are a series of magic that appears in Kingdom Hearts, Kingdom Hearts: Chain of Memories, Kingdom Hearts II, Kingdom Hearts 358/2 Days, Kingdom Hearts Birth by Sleep, and Kingdom Hearts coded. They utilize the element of Lightning, and are associated with the Lightning material. Thunder spells summon lightning bolts from the sky to rain down on enemies, dealing Thunder-type damage.

Thunder is the first magic spell to appear in the Kingdom Hearts series. Donald Duck uses it to wake up a sleeping Goofy.

Kingdom Hearts
In Kingdom Hearts, Thunder calls down bolts of lightning to strike the target area. It is useful for hitting a group of enemies a distance. The higher-tier Thundara and Thundaga call down greater numbers of more powerful lightning bolts. Thunder costs 1 MP to use, and its power is determined by the following equations:
 * Thunder: Power = (Max MPx2)+14.
 * Thundara: Power = (Max MPx2)+18.
 * Thundaga: Power = (Max MPx2)+22.

Donald and the summon Genie have access to any magic Sora has already learned, including the Thunder spell.

Kingdom Hearts: Chain of Memories
In Kingdom Hearts: Chain of Memories, Thunder is a magic card that can be used by Sora.

The Genie summon card, the Donald and Jack Skellington friend cards, and their associated sleights can cast Thunder magic when used.

The Thunder card can be used in the following sleights:

Thunder can also be used within the following sleights, which require a magic card of any type:

Kingdom Hearts II
In Kingdom Hearts II, Thunder drops a lightning bolt on a target, damaging nearby enemies.

Thunder costs 15 MP to use.

Kingdom Hearts 358/2 Days
In Kingdom Hearts 358/2 Days, Thunder, Thundara, and Thundaga are magic panels. Unlike in other games, each tier of the spell has a unique effect. All three Thunder spells may jolt enemies, causing them to take damage from contact with enemies.

Thunder brings down a string of lightning bolts that travels in a straight line.

Thundaga brings down a single, powerful bolt of lightning to strike the target directly.

Kingdom Hearts Birth by Sleep

 * Note: Though the Olympus Coliseum tournaments are not needed to go through the storyline, a second-tier spell may not be acquired before the first-tier. When acquiring any sort of Magic for the first time, the player receives the first-tier spell in lieu of the upgrade that would normally be acquired. Because Olympus Coliseum and Atlantica can both be skipped in Kingdom Hearts, Thunder is one of three spells that can be missed entirely in-game, the others being Stop and Gravity.
