Thunder (サンダー Sandā?), often referred to as Lightning or Electricity, is a recurring element that appear in the Kingdom Hearts series. The Thunder element is associated with the Lightning material and the Jolt and, sometimes, Stun status effects. In Kingdom Hearts 358/2 Days and Kingdom Hearts Re:coded, it is the opposite of Aero.

Attacks and abilities

Throughout the Kingdom Hearts series, party members and enemies alike use attacks and abilities that inflict Thunder damage. Most prominently is the series of Thunder magic, which has appeared in every game as an offensive spell available to playable characters and some party members. Party members also can occasionally use other Thunder-element abilities, either fully original moves or adaptations of Thunder magic. In a number of games, other Thunder-element attacks are also available to the player, such as Thunder Roll, Exo Spark and Thunderstorm. There are also abilities that raises the power of Thunder-based attacks, such as Photon Debugger's Thunder Boost ability, and a Thunder +1 chip in Kingdom Hearts Re:coded.

Thunder Resistance

Thunder Resistance is a recurring stat in the Kingdom Hearts series. Increasing it through various means will reduce the amount of damage taken from Thunder attacks. In most games in the series, Thunder Resistance can be raised by equipping accessories or, in Kingdom Hearts II, armor. In Kingdom Hearts: Chain of Memories, some Enemy Cards have resistance or weakness to Thunder as a secondary effect. Thunder Resistance is raised in Kingdom Hearts Birth by Sleep by equipping the Thunder Screen ability, and in Kingdom Hearts Re:coded by equipping Thunder Resistance Stat Chips in the Stat Matrix (see above).

In Kingdom Hearts 358/2 Days, lightning resistance only protects against the jolt status, not against Fire damage.

Origin

Lightning is a recurring element in the Final Fantasy series. It is one of the earliest elements introduced, and forms a trifecta with the elements of Fire and Ice. Mechanical enemies are typically weak to this element. It is usually the opposing element of Water, but occasionally it can be the opposing element of Poison and Ice.
