Thunder

Thunder (サンダー), Thundara (サンダラ), and Thundaga (サンダガ) magic are attacks used by Sora, Donald, and other characters and enemies that utilize the element of Electricity.

Kingdom Hearts
In Kingdom Hearts, Thunder was a more powerful and costly spell than Fire or Blizzard, summoning a barrage of lightning bolts from above to strike an enemy and any other enemies nearby. It cost 1 MP bar to use.

Kingdom Hearts: Chain of Memories
In Kingdom Hearts: Chain of Memories, there is a Thunder Magic card that can be used in many different Sleights:


 * Thundara
 * Thundaga
 * Thunder Raid
 * Freeze (Re:CoM only)

Keyblades are given elemental properties in this game. Here are the attack cards with a Thunder-based property:


 * Spellbinder
 * Photon Debugger

Kingdom Hearts II
In Kingdom Hearts II, Thunder is more or less equal to the other attack spells, summoning a single lightning bolt to strike one enemy. The area of effect increases with Thundara and Thundaga.

There is a new ability in this game called Thunder Boost, which increases the amount of damage done by Thunder spells. It is also a passive ability from the Photon Debugger Keyblade.

It can be used by:


 * Donald
 * Jack Skellington
 * Tron

Kingdom Hearts 358/2 Days
In Kingdom Hearts 358/2 Days, Thunder sends out a straight line of lightning bolts in front of the caster. Thundara works like the Thunder spells in Kingdom Hearts where lightning strikes randomly around the caster for a period of time. Thundaga invokes a single, enormous bolt of lightning on top of the target.

Kingdom Hearts Birth by Sleep
Thunder magic will be usable again in Kingdom Hearts Birth by Sleep.

Kingdom Hearts
Thunder: Learned after completing Philoctetes barrel challenge. Power equals Max (MPx2)+14.

Thundara: Upgraded after defeating the giant Ursula. Power equals Max (MPx2)+18.

Thundaga: Upgraded after defeating Cerberus in the Hades Cup. Power equals Max (MPx2)+22.


 * Note: Though the Olympus Coliseum tournaments are not needed to go through the storyline, you cannot get Thundara before Thunder. When getting any Magic for the first time, the player receives the first level spell or an upgrade. Therefore, if one defeats Giant Ursula before completing Phil's challenge, they will receive Thunder, not Thundara.
 * Also, because Olympus Coliseum and Atlantica both can be skipped, Thunder is one of two spells that can be avoided entirely in-game, the other being Stop.
