Thunder

Thunder, Thundara, and Thundaga magic are attacks used by Sora, Donald, and other characters and enemies that utilize the element of Electricity. 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. 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.

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