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: Chain of Memories, Kingdom Hearts II, Kingdom Hearts 358/2 Days, Kingdom Hearts Birth by Sleep, Kingdom Hearts coded, and Kingdom Hearts 3D: Dream Drop Distance. 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 -type damage.

In , 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.
