Thunder

Thunder (サンダー), Thundara (サンダラ), and Thundaga (サンダガ) magic are offensive spells used by Sora, Donald, and other characters and enemies associated with the element of lightning. Although named "Thunder", lightning is actually used, not thunder itself.

Kingdom Hearts Birth by Sleep
Thunder is used much differently than its other incarnations. The user casts a ring of lightning around them, and any enemies inside the ring are struck by lightning.

Kingdom Hearts
Thunder was the first magic ability seen, where it was used by Donald to awaken a sleeping Goofy.

In Kingdom Hearts, Thunder was a more powerful and also more costly spell than Fire or Blizzard, summoning a barrage of lightning bolts from above to strike the surrounding enemies at the cost of 1 MP bar.

Characters who cast Thunder magic in Kingdom Hearts:
 * Sora
 * Donald
 * Jack Skellington
 * Ariel
 * Genie

Kingdom Hearts: Chain of Memories
In Kingdom Hearts: Chain of Memories, Thunder appears as a magic card that can be used in the following sleights:
 * Thundara
 * Thundaga
 * Thunder Raid

Keyblades are sometimes given elemental properties in this game. Thunder-elemental keyblades appearing in this game are as follows:


 * Spellbinder
 * Photon Debugger

Kingdom Hearts II
In Kingdom Hearts II, Thunder is approximately equal to the other base elemental spells Fire and Blizzard in power. Thunder has decreased in power in Kingdom Hearts II, as opposed to Fire and Blizzard, which have increased in power from their incarnations in Kingdom Hearts. The spell summons a single lightning bolt to strike an enemy and an area-of-effect that is expanded with each upgrade.

A new ability, Thunder Boost, appearing in Kingdom Hearts II increases the amount of damage caused by lightning-elemental spells. Although it may be learned by leveling up, it is also a passive ability acquired when equipping the Photon Debugger keyblade.

Characters who cast Thunder magic in Kingdom Hearts II:


 * Sora
 * Donald
 * Jack Skellington
 * Tron

Kingdom Hearts 358/2 Days
In Kingdom Hearts 358/2 Days, Thunder sends out a straight line of lightning before the caster. Thundara resembles Thunder magic as it appears in Kingdom Hearts, in which lightning strikes randomly around the caster for a brief period of time. Thundaga invokes a single, enormous bolt of lightning to strike the target.

 * 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.
